Michael Bublé leaves Project panel speechless

<p dir="ltr">Michael Bublé has shared a fan's unique way of dedicating their love, which left <em>The Project</em> panel speechless.</p> <p dir="ltr">The award-winning singer revealed that a fan of his had gotten a tattoo of him which was inspired by an unfortunate photo of him eating a corn on the cob “the wrong way”.</p> <p dir="ltr">“Apparently most people don’t eat it from the top,” he said, urging the program to show the hilarious image which looked quite phallic.</p> <p dir="ltr">“That was the closest thing to a real love note that I’ve ever had and it was sexy and phallic,” he joked.</p> <p dir="ltr">The Canadian superstar was boasting with confidence despite the potentially embarrassing situation.</p> <p dir="ltr">“I feel like people made fun of me, but I think part of it was jealousy because I just think they wish they could take it as deep as I did.”</p> <p dir="ltr">The <em>Feeling Good </em>singer who is currently touring Australia, and promoting his new fragrance, still had his mind in the gutter when <em>Project</em> host Sarah Harris asked him what he “likes to smell on a lady”.</p> <p dir="ltr">Bublé was stunned for a split second before he burst into laughter and replied that there were “so many things” he wanted to say.</p> <p dir="ltr">The segment took another hilarious turn when comedian and panellist Sam Taunton brought out a Michael Bublé cardboard cutout he had borrowed from a chicken shop.</p> <p dir="ltr">“I found this cut out and I saw a lady hugging it actually as well,” he said.</p> <p dir="ltr">“Do you mind if we do some stuff to this?”</p> <p dir="ltr">The audience was left in stitches and Bublé himself was laughing as he said that they could “absolutely” do whatever they wanted.</p> <p dir="ltr"><em>Images: The Project</em></p>

Microwaving solar panels makes them easier to recycle

<div> <p><a href="https://cosmosmagazine.com/news/solar-cells-essential-for-brighter-future/" target="_blank" rel="noreferrer noopener">Solar cell</a> manufacturing and recycling should be easier with a surprising new discovery by Macquarie University scientists – that uses a commercial microwave.</p> <p>While they’re being made, the silicon in solar panels goes through a process called “annealing”, which involves heating the materials to temperatures well above 500°C.</p> <p>Annealing is usually done with ovens. But a study <a href="https://doi.org/10.1063/5.0127896" target="_blank" rel="noreferrer noopener">published</a> in Applied Physics Letters shows that microwaves are not only faster and more energy efficient for the job, but make the panels much easier to disassemble, and thus recycle, at the end of life.</p> <p>This is because microwave radiation heats individual substances – like the water in food, or silicon.</p> <p>“It just heats the very thin layer of silicon rather than heating the bulk of the materials around, and it’s really fast,” says lead author Dr Binesh Puthen Veettil, a researcher at Macquarie University’s School of Engineering.</p> <p>This also makes the process easier, because the microwave doesn’t have to be as carefully cleaned.</p> <p>“In most of the high temperature processes, lots of contaminants come out of the walls of the oven. But in this case, the heat is flowing from the silicon outwards, while everything else is at room temperature, it’s kind of a pseudo room temperature process where the contaminants don’t get diffused from outside,” says Veettil.</p> <p>“But the thing we are most excited about is the benefit to recycling.”</p> <p>Currently, solar cell recycling is a very <a href="https://cosmosmagazine.com/earth/sustainability/solar-panel-recycling/" target="_blank" rel="noreferrer noopener">energy intense process</a> which involves crushing up the panels and heating them to temperatures of at least 1000°C, so that all of the expensive elements can be extracted.</p> <p>This method destroys some of the reusable solar cell components: particularly, the toughened glass on the top of the panel.</p> <p>“This glass contains most of the weight of the solar panel,” explains Veettil.</p> <p>That glass is stuck to a layer of plastic, usually ethylene vinyl acetate, which keeps the silicon plate underneath dry. This plastic is too hard to remove, so the whole thing is smashed up, with the glass sold as scrap.</p> <p>But microwaving the silicon specifically softens the plastic, making it easy to peel.</p> <p>“You can just peel off the silicon cell, without destroying the glass, and you can reuse that expensive glass,” says Veettil.</p> <p>“If you can reuse the glass, the recycling will pay for itself.”</p> <p>Plus, it doesn’t need the same high temperatures, or extra chemicals needed to wash and dissolve the plastic.</p> <p>For now, the process is lab-based – and only for solar panels that fit in a commercial microwave.</p> <p>“Initially, when we started the research, we used a laboratory microwave that we purchased from a US company,” says Veettil.</p> <p>“And we after that, we purchased some kitchen microwaves locally, and modified it to suit our purposes.”</p> <p>This modification involved heat-proofing the microwave so that it could handle the annealing temperatures.</p> <p>“It goes from room temperature to 500° Celsius in just two seconds,” says Veettil. (Depending on the size of the sample: bigger things take longer.)</p> <p>But the researchers have a patent pending for the recycling process, and are now investigating how to improve and commercialise it.</p> <p>“We are hoping that with some industry collaboration and funding, we can scale it up,” says Veettil.</p> <p>“Recycling needs to be meet two conditions: it should be environmentally friendly, and second, it should pay for itself.</p> <p>“I’m pretty sure, with the numbers I have in mind, it will it will be profitable and then the market will take care of itself and it organically grow recycling centres. That’s my hope.”</p> </div> <div id="contributors"> <p><em>This article was originally published on <a href="https://cosmosmagazine.com/technology/microwaving-solar-panels-recycling/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Ellen Phiddian.</em></p> <p><em>Images: Getty</em></p> </div>

Travelling around the globe might not have to cost the Earth

<p>The last time you booked a flight online, you may have been offered the chance to ‘offset’ the carbon produced by your travel. This is due in part to recognition that the aviation industry is responsible for around 5% of human-made emissions resulting in climate change.</p> <p>The efforts by this sector to respond to its environmental impact can range from switching fuels (from coal to biomass, for instance), more efficient combustion processes (by improving aircraft engines, for example), protecting forests or promoting sustainable development in local communities.</p> <p>Now, in a potentially ground-breaking innovation for long-haul flights, a team of researchers at the Swiss Federal Institute of Technology, Zürisch (ETH Zurich) have developed an all-in-one solar-powered tower that’s able to use energy from the Sun’s rays to convert water and carbon dioxide into synthetic fuels.</p> <p>Think: water + carbon dioxide = energy. Sound familiar? Well, it should. It’s what many plants do to make energy for themselves.</p> <p>The ETH Zurich process has a lot in common, really, explains Dr Jessica Allen, a chemical engineer and renewable energy technologies expert at the University of Newcastle. Although in this case, “industrial photosynthesis might be a better term as this particular process doesn’t involve any physiological mechanisms like plants and living material”, says Allen.</p> <p>The proof-of-concept solar tower consists of 169 Sun-tracking panels that reflect and concentrate sunlight into a tower-top solar reactor. Here, energy from the Sun’s rays meets a combination of water, carbon dioxide and a special structure made of ceria (cerium oxide), which is porous and “acts like a filter network, undergoing many reduction-oxidation (also known as redox) reactions”, says Allen.</p> <p>These reaction cycles produce syngas (synthesis gas), which is then converted to liquid fuels such as diesel and kerosene (which is used as jet fuel for long-haul flights) via a well-established process known as the Fischer-Tropsch reaction, which typically occurs in the presence of metal catalysts, temperatures of 150–300°C and pressures of several tens of atmospheres.</p> <p>Much work remains to translate the process to industrial scale. Currently, the energy efficiency of the process is only at 4%, meaning that out of 100 parts of energy available, only four parts are captured in the process. This is something the researchers are keen to push up towards around 15%.</p> <p>According to Allen, that’s still at the low end of the energy efficiency of current solar-to-electricity and solar-to-thermal energy generation. She says that efficiency is crucial when it comes to systems that use land area for solar collection (such as solar panels and the ETH Zurich tower’s reflectors): “A low efficiency will mean a large land area to generate the required fuel.”</p> <p>Where the CO2 comes from is also very important. At present, it’s injected into the system, but the next obvious step is to start capturing it directly from the air. At that point the fuel production process might be considered carbon neutral, as the amount of CO2 captured from the air is the same as the amount released during fuel combustion.</p> <p>Direct-from-air carbon dioxide capture comes at a cost, though. “There is a fairly major energy penalty for doing direct air capture, because it’s quite hard to filter out carbon dioxide from the rest of the gasses,” says Allen.</p> <p>Then there’s the carbon footprint related to the manufacture and production of equipment and materials, but Allen urges a long-term outlook: “In the system that we’re in at the moment there will be an emission penalty for the materials, however, in the long term, we’ll eventually be manufacturing these things using zero emission approaches.” This will make the whole process – and not just the fuel itself – carbon neutral.</p> <p>The average fuel consumption of a Boeing 747 (which are still used as long-haul cargo transport today) is around 4L per second. For a flight of 10 hours, this equates to 144,000L of fuel.</p> <p>In the future, EHT Zurich researchers will work to increase the system’s energy efficiency to 15%, capture more heat in the process and improve the ceria structures in the reactor in addition to capturing CO2 directly from the air. Their long-term aim is to scale the process to an industrial size – in which enough fuel can be produced to truly fly us into a carbon-neutral aviation future.</p> <p><em><strong>This article originally appeared on <a href="https://cosmosmagazine.com/science/carbon-neutral-travel-wont-cost-earth/" target="_blank" rel="noopener">cosmosmagazine.com</a> and was written by Clare Kenyon.</strong></em></p> <p><em>Image: Shutterstock</em></p>

How to choose the best solar panels for your home

<p dir="ltr">The solar industry has seen a rapid growth over the past decade and become the cleanest, greenest and cheapest source of electricity.</p> <p dir="ltr">As electricity bills continue to rise at an exponential level, switching to solar makes sense. </p> <p dir="ltr">With many solar providers out there offering different services for widely differing costs, it's easy to get lost in the semantics of switching to solar. </p> <p dir="ltr">Luckily, Beau Savage, Co-Founder of <a href="https://smartenergy.co/au/">Smart Energy</a>, has shared his top tips to consider when finding the right solar provider for your home.</p> <p dir="ltr"><strong>Evaluate your home</strong></p> <p dir="ltr">The first step is to figure out if solar power is right for you. </p> <p dir="ltr">There are a few reasons why solar might not suit, including renters, apartment-dwellers, and anyone who lives in a shady spot might not be the ideal candidate for solar power.</p> <p dir="ltr">Luckily there are other ways to reduce your carbon footprint.</p> <p dir="ltr">“If conditions don’t suit, it might be better to invest in a 100 per cent carbon neutral energy plan,” says Beau.</p> <p dir="ltr"><strong>Do your research</strong></p> <p dir="ltr">Shopping for solar is no different to buying new furniture. </p> <p dir="ltr">It’s important to shop around for the best deal by looking at user reviews, comparing prices and services, and talking to experts before locking down a provider. </p> <p dir="ltr">Beau says, “The only negative reviews you want to see appearing on a good company should be from those who delayed getting and wished they’d done it sooner.”</p> <p dir="ltr"><strong>Find the right company</strong></p> <p dir="ltr">While there’s nothing wrong with prioritising affordability and cost comparison, be aware that low costs can occasionally translate to poor customer service and unreliable installers.</p> <p dir="ltr">According to Beau, “For the best long term results, choose a solar company who uses local installers so that if there is a problem, there will always be someone ready to immediately fix the issue.”</p> <p dir="ltr"><strong>Find the right spot</strong></p> <p dir="ltr">When it comes to solar power, location is key. </p> <p dir="ltr">The last thing you want is to discover that your installer has placed the panels in a bad spot, which only leads to more costs to correct the error. </p> <p dir="ltr">“When having an initial consultation it is essential to ask whether or not the company you are talking to sends trained engineers who can look at your roof, its shading and sunlight levels. This will ensure that you will get the most out of your solar system.”</p> <p dir="ltr">In order to get the most of your solar power, make sure there are no obstructions to your panels, and be sure to monitor the system’s performance to make sure you’re getting the very best green energy. </p> <p dir="ltr"><em>Image credits: Getty Images</em></p>

Solar curtailment is emerging as a new challenge to overcome as Australia dashes for rooftop solar

<p>Almost <a href="https://www.smh.com.au/environment/climate-change/australia-reaches-3-million-households-with-rooftop-solar-20211108-p59721.html">a third</a> of Australia’s estimated <a href="https://www.ibisworld.com/au/bed/number-of-households/31/">ten million households</a> now have solar on the roof. But as the nation moving fastest to produce energy on our homes, we are also encountering teething problems, such as “curtailment” of output.</p> <p>This issue will be one we have to overcome as ever more Australians install solar. Our grids were designed primarily for large fossil fuel power stations transmitting electricity in one direction, while solar households both consume and export power.</p> <p>That means in some conditions, household solar may contribute to spikes in voltage levels outside of the acceptable range, especially as voltage levels are typically already high.</p> <p>To counter this, your solar system can stop exporting to the grid or even shut down temporarily if voltage levels are too high. This is called “curtailment”.</p> <p><a href="https://images.theconversation.com/files/436513/original/file-20211209-21-qfm0ve.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/436513/original/file-20211209-21-qfm0ve.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Solar technicians installing panels" /></a> <span class="caption">The rush for solar shows no signs of slowing – but curtailment could be a stumbling block.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>So what’s the issue?</h2> <p>The average solar household lose less than 1% of its power production to curtailment – and even less for those with home batteries. While that sounds minor, an unlucky few households are losing as much as 20%.</p> <p>Why the drastic difference? It depends on factors like the house’s location, the local electricity network equipment, home wiring, the number of solar systems in the area, and the size of a solar system and inverter settings, which can vary depending on the date of installation.</p> <p>These findings are from <a href="https://www.racefor2030.com.au/wp-content/uploads/2021/11/CANVAS-Succinct-Final-Report_11.11.21.pdf">our scoping study</a> in South Australia, conducted in partnership with AGL, SA Power Networks and Solar Analytics as part of the <a href="https://www.racefor2030.com.au/">RACE for 2030</a> research centre.</p> <p>We analysed two out of three modes of automatic curtailment, with further research underway to assess the third mode, which may account for greater overall curtailment.</p> <p>This issue is set to get bigger, as more and more solar systems are installed and export to the grid at the same time.</p> <p>Given the different ways solar households experience curtailment, this research also raises issues of fairness.</p> <p>Our research interviewed and ran focus groups with South Australians who have solar. We found most participants didn’t know about curtailment and hadn’t experienced it or noticed it.</p> <p>But when we described curtailment, most people found it off-putting and questioned whether rooftop solar owners should be made to absorb any losses, given the contribution of rooftop solar to the renewable energy transition.</p> <p>Not only that, our participants told us they believed the issue could slow down the adoption of solar and potentially undermine faith in the system.</p> <p><a href="https://images.theconversation.com/files/436514/original/file-20211209-19-azcfvo.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/436514/original/file-20211209-19-azcfvo.jpg?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt="Power pylons" /></a> <span class="caption">Australia’s rapid renewable transition means challenges to overcome for the grid.</span> <span class="attribution"><span class="source">Shutterstock</span></span></p> <h2>Is this a problem for solar uptake?</h2> <p>The issue of curtailment means people may not get everything they expect out of their solar system. But this may not be a deal breaker, given <a href="https://ecss.energyconsumersaustralia.com.au/behaviour-survey-oct-2021/purchase-intentions/">earlier research</a> and our study both show that people hope to benefit in many different ways from installing a solar system.</p> <p>For instance, some want to reduce their reliance on fossil fuels and contribute to a cleaner grid. Others want to be less reliant on electricity providers and enjoy producing and using their own energy. And some just want cheaper electricity, and don’t mind whether they get these savings through selling their power or just buying less of what they need from the grid.</p> <p>The good news is that as the solar sector matures, new ways are emerging of maximising value from our solar, including:</p> <ul> <li>home energy management systems letting us time the use of appliances such as <a href="https://www.pv-magazine-australia.com/2021/09/06/unsw-study-channelling-rooftop-pv-into-water-heating-is-a-residential-super-saver/">hot water tanks</a> for daytime periods, when solar generates most power</li> <li>batteries letting us store power for use in the home when it is needed, such as in the evening</li> <li><a href="https://www.solarpowerworldonline.com/2017/09/virtual-power-plant/">virtual power plants</a> enabling households to be paid for allowing their solar and battery systems to help stabilise the electricity grid.</li> </ul> <p>While attractive in their own right, these options can also reduce how much your solar system is curtailed, and have the potential to help tackle challenges at a grid scale.</p> <p>Other changes to electricity and grid access and pricing could also help us better manage curtailment.</p> <p><a href="https://www.abc.net.au/news/2021-04-15/sa-power-networks-to-control-solar-exports-in-adelaide-trial/100070068">Flexible export limits</a> being trialled in South Australia and elsewhere would mean households could export electricity to the grid when it is needed, while occasionally being prevented from doing so when the network does not have capacity.</p> <p>Flexible export limits also mean households can install larger solar systems regardless of their location within the network. They could stop curtailment affecting solar households in unexpected and uneven ways.</p> <p>Other responses include <a href="https://discover.agl.com.au/solar/helping-to-maximise-your-solar-savings/">programs to reward households</a> for having their export curtailed, recognising it as a service to the market and the network.</p> <p>There is no single solution to the issue of curtailment. But the different solutions described above may contribute to the successful integration of more rooftop solar energy and pave the way for a more renewable grid.</p> <p>Now is the time to talk about the future of solar in Australia, and the ways we can value it, use it and manage it when abundant.<!-- Below is The Conversation's page counter tag.

Australia's pork panel officially reveal the best value Christmas ham in Australia

<p>The Christmas ham is the glistening centrepiece of every table come this time of the year.</p> <p>With the big day fast approaching, the question on the minds of many is: Where do I get the “perfect” ham? There is where Australian Pork steps in. To help narrow It down, CEO Margo Andrae has stepped in to let shoppers know what to choose and what to look for when buying their Christmas ham.</p> <p>“We know from our research that over 78% of shoppers will purchase their ham from their local supermarket. With our Supermarket Ham Taste Test, we want to take the work out of choosing a ham for Australians, and provide a cheat sheet for any budget and any celebration size this year,” Ms Andrae says.</p> <p>Ms Andrea, together with celebrity chef Adrian Richardson and award-winning free range pig producer Judy Croagh, blind taste-tested 20 hams from all the major retailers on best taste and value.</p> <p>All making their way through the pork, it was Woolworth’s Double Smoked Half Leg Ham at $12.50/kg that has taken the crown for best pork in 2021.</p> <p>Judges described it as having a sweet and light aroma, clean robust appearance and deliciously delicate taste.</p> <p>The overall Value Ham also came from Woolworths, with the Half Leg Ham available at $8.50/kg.</p> <p>“This ham had a beautiful balance smoky aroma, flavour with a good bite,” said one of the judges.</p> <p>Woolworth’s commercial director Jason McQuaid said they’re thrilled both hams have been recognised with these awards.</p> <p>“With customers starting to plan their Christmas celebrations, we’re expecting more than 1.75 million kilos of our Woolworths Half Leg Ham, a 20% increase from last year, to fly off the shelves in the lead up to Christmas,” Mr McQuiad said.</p> <p>Coles, Costco and IGA’s top hams cost just $8.50 a kilo, with Aldi’s best-selling ham just a few dollars more at $11.99.</p> <p>The judges were blown away by the free-range Berkshire full leg ham on the bone from</p> <p>Costco, awarding it the Premium Buy at $19.99 per kilogram.</p> <p>Ham sales have gone up 20 per cent from 2020, as families prepare for a much-needed celebration after another tough year.</p> <p><strong>GLAZING YOUR HAM</strong></p> <p>This comes down to four steps, as recommended by Australian Pork.</p> <ol> <li>Prepare your favourite glaze recipe</li> <li>Remove rind and use a sharp knife to score ham in a diamond pattern</li> <li>Place ham scored side up in a large baking pan and brush over glaze</li> <li>Place into a preheated oven or hooded barbecue at 180°C for 20 minutes per kg, basting occasionally, until ham is brown and warmed through</li> </ol> <p><strong>STORING YOUR HAM</strong></p> <ol> <li>Soak a Ham Bag, pillowcase or tea towel in 4 cups of water and 2 tbsp vinegar</li> <li>Wring out excess liquid and place or wrap ham inside</li> <li>Store in coolest part of fridge</li> <li>Re-soak bag in solution every few days or when Ham Bag dries out</li> </ol>

Beware the lure of unethical solar power

<div> <div class="copy"> <p>Solar energy may be the future. But only if it lets go of the past.</p> <p>International NGO the <a rel="noreferrer noopener" href="https://www.weforum.org/agenda/2021/09/to-lead-the-green-energy-future-solar-must-clean-up-its-supply-chains/" target="_blank">World Economic Forum</a> has issued a damning report card on the state of the world’s solar panel manufacturing. It may be experiencing rapid growth. It may be one of the cheapest sources of power. But its climate credentials face intense scrutiny.</p> <p>Forced labour, coal-fuelled production processes and a lack of transparency around the source of crucial components combine, the WEF says, into a cause for concern.</p> <p>“The solar industry is currently grappling with supply chain issues that could significantly impact its future,” the authors, professors Morgan Bazilian and Dustin Mulvaney, write.</p> <p>Much of their concern is concentrated on the production of polysilicon and the drive to make it cheap.</p> <p>Some 45% of global production of this component is sourced from Xinjiang province in China. And much of the labour force used to produce it is supplied by “re-education camps” detaining ethnic Kazakhs and Kyrgyz. </p> <p>On top of that, the remote desert region relies heavily on locally sourced coal for its power supply. “This attracted polysilicon manufacturers to this region of China in the first place because electricity is a major cost in the production process,” the report reads.</p> <p class="has-text-align-center"><strong><em>Read more: <a rel="noreferrer noopener" href="https://cosmosmagazine.com/technology/solar-and-wind-cheapest-energy-source-in-australia/" target="_blank">Solar and wind cheapest energy source in Australia</a></em></strong></p> <p>This, they say, undermines any climate and environmental benefits offered by solar panels further down the supply chain.</p> <p>“Solar panels are cheaper to build and install today in many places than alternative sources of electricity like coal and natural gas, translating to lower levels of greenhouse gases and air pollution,” they write.</p> <p>But Professor Alistair Sproul of the ANU’s School of Photovoltaic &amp; Renewable Energy Engineering says photovoltaic power has more than enough wiggle room in its pricing to clean up its act. Much of the price drop in photovoltaic (PV) production in recent years has been driven by advances in technology, particularly crystalline silicon, he says. “Even if the price stayed where it is now or went up a little – PV is very cost-competitive.”</p> <p>Under current life-cycle <a rel="noreferrer noopener" href="https://www.nrel.gov/analysis/life-cycle-assessment.html" target="_blank">calculations</a>, crystalline silicon PV cells produce about 50g of <span>CO<sub>2 </sub></span>for every kilowatt-hour of electricity. Black coal, in comparison, comes in at 1000g of <span>CO<sub>2</sub></span> per kWh. </p> <p>“The PV industry is growing each decade or so by a factor of 10 – this next decade is crucial – but as scale increases, costs will come down anyway – and the industry is not reliant on forced labour,” says Sproul.</p> <p>“Low-cost energy is really key here – so that there is a virtuous cycle – that as PV itself becomes cheaper it should be possible to lower the cost of producing PV further by utilising increasing amounts of PV electricity in manufacturing.”</p> <p>Sproul says materials that need coal for processing – especially steel – are all seeking alternatives.  “Hydrogen is definitely an avenue worth exploring as an alternative to coal to reduce iron oxide (for steel)  and silicon dioxide ( for silicon). [And] all supply chains need to be clear, transparent and free from forced labour.”</p> <em>Image credit: Shutterstock                         <!-- Start of tracking content syndication.

Mum's urgent warning against exploding Christmas lights

<p>A mum has raised concerns after a set of solar-powered lights from Kmart exploded in the sun and severely burnt a wall outside her home.</p> <p>The woman from Queensland recently took to Facebook to warn others in case the same thing happens to them, as she shared multiple photos revealing the damage caused by the explosion.</p> <p>She reassured that no one was hurt and thanks to quick-thinking neighbours, embers were extinguished before dry glass was set alight.</p> <p>“Thank God for neighbours or things could have been a lot worse,” she captioned her post.</p> <p>“Solar panel on Xmas lights exploded. Bought them from Kmart approx. (sic) 3 weeks ago.</p> <p>“Will be notifying the store I brought them from tomorrow.”</p> <p>Kmart is currently selling Anko branded solar-powered LED multi-coloured string lights for $34 for a pack of 500.</p> <p style="text-align: center;"><img style="width: 480px; height: 480px;" src="https://oversixtydev.blob.core.windows.net/media/7833577/1.jpg" alt="" data-udi="umb://media/b920f6ca3e2c41d0a3cd1f2f79a337ee" /></p> <p>According to information on the store’s website, the lights are suitable for outdoor use.</p> <p>“Set the mood for the Christmas season with our festive LED string lights that will look stunning in your backyard!” reads the product description.</p> <p>Since sharing her warning, the post has received over 1800 reactions and hundreds of comments from concerned people.</p> <p>“My husband’s just gone to take ours down,” wrote one person. “I don’t know if it’s the same type but they are from Kmart so not risking it.”</p> <p>While another added: “This is so concerning! Glad I don’t have any of them, but not so good for the thousands of people that do!”</p> <p>A spokesperson from Kmart said the retailer had reached out to the customer to offer support as part of a commitment to ensuring all products are “fully compliant with regulations and safety standards”.</p> <p>“At Kmart Australia safety is our number one priority and we are committed to ensuring the products we sell are fully compliant with regulations and safety standards,” said the spokesperson.</p> <p>“We have reached out to the customer to offer support and conduct a review of their case.”</p>

Are you a frequent flyer? Solar storm radiation can be harmful

<p>Space weather <a href="https://theconversation.com/solar-eruption-could-help-earth-prepare-for-technology-melt-down-18747">impacts</a> many modern-day technologies. But one of the most concerning – and least reported – space weather effects is the increased radiation exposure to passengers on commercial long-distance flights during so-called “<a href="http://www.spaceweather.com/glossary/srs.html">solar radiation storms</a>”.</p> <p>The NASA-funded Nowcast of Atmospheric Ionizing Radiation System (<a href="http://sol.spacenvironment.net/~nairas/">NAIRAS</a>) is the computer system tasked with providing a real-time data-driven climatology of the aviation radiation environment.</p> <p>Recently, a series of papers published in the journal [Space Weather] estimate that when NAIRAS was turned off during the US government shutdown last year – which went into effect just as a solar radiation storm began – <a href="http://onlinelibrary.wiley.com/doi/10.1002/2013SW001015/abstract">500,000 people</a> received increased radiation doses.</p> <p>It has also been estimated that this event is likely to eventually result in four cancer-related deaths.</p> <p><strong>What is a solar radiation storm?</strong></p> <p>Disturbances on the surface of the sun are commonly the cause of geomagnetic disturbances here on Earth; such as power grid faults/failures and increased errors in GPS navigation and positioning.</p> <p>Associated with some of these solar disturbances is the ejection of extremely fast plasma into the solar wind that, when aimed directly towards the Earth, causes the onset of increased geomagnetic and ionospheric activity.</p> <p>The Earth-bound solar energetic particles ejected into the solar wind eventually penetrate into the Earth’s magnetosphere.</p> <p>When inside the magnetosphere, they orbit the planet across the Earth’s magnetic field lines until they are scattered by various complicated magnetospheric processes and interactions.</p> <p>Once scattered, these solar particles then travel down the magnetic field lines until they impact the Earth’s upper atmosphere, where they are effectively absorbed.</p> <p>The penetration depth of these particles primarily depends on their kinetic energy, which is governed by their mass and velocity.</p> <p>The less energetic particles are stopped by the Earth’s atmosphere typically between 100 and 400km altitude, causing the well-known <a href="http://spaceweathergallery.com/aurora_gallery.html">aurora</a> in the northern and southern high-latitude regions.</p> <p>The atmosphere increases in density exponentially as the particle falls. This normally prevents particles penetrating to lower altitudes where they are harmful to living organisms.</p> <p>The more energetic particles, called “solar energetic particles”, caused by these solar disturbances can <a href="http://www.dartmouth.edu/~barrel/index.html">penetrate</a> to below 10km, near of commercial flights.</p> <p>During such events, the danger posed by the increased radiation levels is easily averted by decreasing the cruising altitudes of the aircraft. Pilots can also divert their flight paths to areas less affected by the increased radiation levels (more equatorward latitudes).</p> <p><strong>Several chest X-rays worth of radiation</strong></p> <p>The aviation radiation monitoring performed in real-time by computer systems such as NAIRAS can effectively be used to issue such warnings to aircraft.</p> <p>This will help remove the threat posed to hundreds of thousands of people across the globe during such space weather events.</p> <p>The geomagnetic activity levels associated with the solar radiation storm that occurred during the US government shutdown were only minor (a minimum <a href="https://theconversation.com/solar-eruption-could-help-earth-prepare-for-technology-melt-down-18747">Dst</a> of -54nT).</p> <p>This means the technologies normally classified as being <a href="https://theconversation.com/divert-power-to-shields-the-solar-maximum-is-coming-11228">vulnerable</a> to extreme space weather events are not likely to have been significantly affected.</p> <p>The solar energetic particle levels observed by <a href="http://www.ngdc.noaa.gov/stp/satellite/goes/index.html">geostationary satellites</a> classifies this as an <a href="http://www.spaceweather.com/glossary/srs.html">S2</a>solar radiation storm. It lasted more than 24 hours, and took about four days to fully subside (see video below).</p> <p>Some controversy exists around the exact method used by the scientists of the first <a href="http://onlinelibrary.wiley.com/doi/10.1002/2013SW001015/abstract">study</a>into this event. There has been doubt around the estimation of the number of eventual cancer fatalities related to this solar radiation storm.</p> <p>Even though the radiation levels air travellers were exposed to during this event are much higher than they might have been had an appropriate warning been issued, they were still comparatively low – on par with the dose that one would receive from a number of chest X-rays.</p> <p>Arguments put forward by some <a href="http://onlinelibrary.wiley.com/doi/10.1002/2014SW001074/abstract">researchers</a> err on the side of caution.

How solar panels can help you cut the cost on your electricity bill

<p><span style="font-weight: 400;">New research from the University of South Australia has shown that battery power storage has reached a tipping point where it’s worth the money and can help save families money.</span></p> <p><span style="font-weight: 400;">Samantha Corns’ family of five uses batteries to power their home. The battery stores energy generated by her rooftop solar panels and costs her $9,000 after subsidies.</span></p> <p><span style="font-weight: 400;">It has dramatically decreased her power bills.</span></p> <p><span style="font-weight: 400;">“We should be absolutely zero, in credits actually,” Ms Corns told  </span><a href="https://www.9news.com.au/national/new-research-finds-battery-storage-can-save-families-money/c09411f6-4dfe-4127-a7a2-ddc7dcf62a6f"><span style="font-weight: 400;">9News</span></a><span style="font-weight: 400;">.</span></p> <p><span style="font-weight: 400;">“It just made financial sense then.”</span></p> <p><span style="font-weight: 400;">Researcher Vanika Sharma agrees.</span></p> <p><span style="font-weight: 400;">“They can actually save money now, if they get the right battery at the right size, at the right price,” researcher Vanika Sharma said.</span></p> <p><span style="font-weight: 400;">However, it’s important to do your research before jumping into the world of solar panels. This includes knowing the size of current solar panels, how much energy your household consumes per day, the price of power currently and how much you’d get for feeding the power generated from the battery back.</span></p> <p><span style="font-weight: 400;">“Definitely we need something to become reliable... and the battery storage is that. It will make that solar energy reliable,” Ms Sharma said.</span></p>

Family's despair after power bills increase by 400% due to law change

<p>When Lee and Warren Mullaly purchased their new home in Forster, NSW they were thrilled. Having pre-installed solar panelling would ensure that their electricity bill would remain low, and while that was the case for a period of time, this year, the semi-retired couple are paying over $400 each quarter.</p> <p>“The government incentive finished and even though we were aware this was going to happen, we still thought our bills were going to be significantly lower,” Lee Mullaly told <em><a rel="noopener" href="https://www.news.com.au/finance/money/costs/changes-to-solar-feedin-tariffs-have-caused-huge-increases-to-power-bills/news-story/a5bafadf063bcb2f99b0d739feac0296" target="_blank">News.com.au</a></em>.</p> <p>Without a battery, the Mullaly's only find their solar panels beneficial during the day as the power produced must be used immediately.</p> <p>And in the evenings when the panels are not generating electricity, any power they use during that period comes from the grid. With their bill previously coming in at $95 a quarter, they are now facing an increase of $1400 more than what they paid the year before.</p> <p>This is the consequence of the Solar Bonus Scheme that was initiated by the NSW Government, ending on 31 December 2016. With the scheme paying households 60c or 20c per kilowatt an hour for the electricity they provided to the grid, many families benefited greatly.</p> <p>Now, as the scheme has shut down, households have taken a hit, and with a battery costing $15,000 to install for the semi-retired couple, the Mullaly's believe that the outlay wouldn’t be worth it.</p> <p>“We’ve got to watch what we spend, we haven’t got a lot of money coming in and we’ve got to weigh up the benefits,” said Lee Mullally.</p> <p>The Independent Pricing and Regulatory Tribunal (IPART) sets a recommended price for retailers, but it is not mandatory for retailers to follow. This year, the suggested benchmark dropped by 44 per cent due to below average wholesale electricity prices.</p> <p>Solar expert and ShineHub co-founder Alex Georgiou said this year’s changes to feed-in tariff rates could see families losing around $300 a year on a 5-kilowatt system.</p> <p>“If a person is not home to use solar power during the day, around 75 per cent of this is sent back to the grid,” he said.</p> <p>While an average household could have earned $657 a year selling power to the grid at a price of 12 cents, this year, that price would drop to $355 if they get 6.5 cents.</p> <p>When asked if she would consider a solar panelling system now, Mrs Mullaly said she would never do it without installing a battery first.</p> <p>“If you are thinking about getting panels you need to get a battery because ultimately it will be a huge saving and will take the worry away.”</p> <p>Do you have solar panelling on your home? Tell us in the comments below. </p>

Studio 10 panel faces off against Senator David Leyonhjelm over “bitch” slur

<p>This morning, Senator David Leyonhjelm faced off against the <em>Studio 10</em> panel in a heated appearance where he refused to apologise for calling co-host Angela Bishop a “bitch”.</p> <p>On the weekend, Leyonhjelm called Bishop a “bigoted bitch” on Twitter, following a segment where the host described his sexist remarks against Greens senator Sarah Hanson-Young as “pathetic”.</p> <p>Leyonhjelm appeared on the show today to discuss his remarks and share his views on “free speech”.</p> <p>"You think it's proper to call women bitches?" fill-in panellist Hugh Riminton asked the senator.</p> <p>"When they are bitches," Leyonhjelm replied.</p> <p>After refusing to apologise for calling Hanson-Young a “serious misandrist”, Bishop asked the Senator to explain the remarks he made about her on his social media account.</p> <p>"I'm not a misandrist. Why did you call me a bitch?" she asked.</p> <p>"Because you were being bigoted," he replied, highlighting the moment when Bishop’s co-host, Joe Hildebrand, had been “trying to explain the context” of the senator’s controversial remark.</p> <p>"Why not call her a bigot, why do you call her a bitch? Real men don't call women bitches," Riminton said.</p> <p>"Oh, you've had a very sheltered life, Hugh," Leyonhjelm replied. "You're entitled to your opinion... I mix with normal Australians and they use that language all the time."</p> <p>Halfway through the segment, Leyonhjelm toned down his defence and said to Bishop: “I'm sorry you took offence."</p> <p>"So do you admit that calling her a bitch was wrong?" host Harris asked.</p> <p>"Oh no," Leyonhjelm replied, causing gasps in the audience.</p> <p>Riminton later tweeted a behind-the-scenes photo of Leyonhjelm and Bishop, saying that the senator admitted “he probably shouldn’t have said it in public”.</p> <blockquote class="twitter-tweet"> <p dir="ltr"><a href="https://twitter.com/hashtag/DavidLeyonhjelm?src=hash&amp;ref_src=twsrc%5Etfw">#DavidLeyonhjelm</a>’s off-camera concession after calling ⁦<a href="https://twitter.com/AngelaBishop?ref_src=twsrc%5Etfw">@AngelaBishop</a>⁩ a “bigoted bitch” - “I probably shouldn’t have said it in public.” ⁦<a href="https://twitter.com/tendailyau?ref_src=twsrc%5Etfw">@tendailyau</a>⁩ ⁦<a href="https://twitter.com/channeltennews?ref_src=twsrc%5Etfw">@channeltennews</a>⁩ <a href="https://twitter.com/hashtag/auspol?src=hash&amp;ref_src=twsrc%5Etfw">#auspol</a> <a href="https://t.co/5kRiX60NvN">pic.twitter.com/5kRiX60NvN</a></p> — Hugh Riminton (@hughriminton) <a href="https://twitter.com/hughriminton/status/1014297298921091072?ref_src=twsrc%5Etfw">July 3, 2018</a></blockquote> <p>During the interview, Bishop questioned Leyonhjelm’s intentions with his recent controversial remarks, suggesting he was using the publicity for his re-election campaign.</p> <p>"That might be an outcome of it, but I didn't set out to achieve that... I didn't try to stop the ball but I also didn't start it," Leyonhjelm said.</p> <p>"You guys keep ringing me up to come and do interviews," he told the panel. "Free speech is important but so is sexism and calling out misandry."</p> <p>Leyonhjelm said he would only apologise for his comment about Hanson-Young if the Greens senator made three public announcements rejecting “men’s collective responsibility” in violence against women – a condition she has since rejected.</p> <p>What are your thoughts?

Q&A panel to Barnaby Joyce: “Staying quiet would be a good idea now”

<p>They tried to talk about anything else but in the end, the ABC’s Q&amp;A was always going to have to tackle the Barnaby Joyce affair that has beset Australian politics for the past two weeks.</p> <p>It did take 20 minutes to get to the subject but when they did, the feeling was unanimous.</p> <p>Barnaby: Just stop talking, mate.</p> <p>The Q&amp;A panel consisting of Deputy Opposition leader Tanya Plibersek, Greens leader Richard Di Natale, Minister for Law Enforcement and Cybersecurity Angus Taylor, British author Kamila Shamsie and the Daily Telegraph journalist who broke the Barnaby Joyce story Sharri Markson all were stunned with Joyce’s comments made on the weekend.</p> <p>Despite resigning a week ago and asking for privacy, the former deputy PM had on the weekend given an interview claiming there was a “grey area” over whether he is the biological father of partner Vikki Campion’s baby.</p> <p>Both sides of politics on the panel were agreement that Joyce should just stop talking.  </p> <p>“I have to say, having read his comments over the weekend, I was lost for words,” said Di Natale.</p> <p>“I thought it was a particularly low thing to do, to accuse somebody of that.</p> <p>“And at this point I think there’s the welfare of former staffer, family with four kids, a child and I think we should just let them get on and sort out what is a very difficult situation.”</p> <p><img width="437" height="246" src="http://cdn.newsapi.com.au/image/v1/70880088f590fa191ab3b4a3eec9efef" alt="“I think staying quiet would be good idea,” Ms Plibersek said. Picture: ABC" style="display: block; margin-left: auto; margin-right: auto;"/></p> <p>Plibersek concurred, saying, “I think if I were advising Barnaby Joyce, I would think staying quiet would be good idea.”</p> <p>“He’s feeding the hand that bites him at the moment,” she added.</p> <p>When an audience member challenged Markson on why Joyce didn’t deserve the same level of privacy “surrounding his private life and offered the same courtesy you believe the targets of Michaelia Cash’s rant does”, Markson said they were two completely different topics.</p> <p>“In the one instance with Michaelia Cash, she threatened to name young women who are the subject of rumour when nothing had been proven at all and they are not public figures. And it’s not even true as far as I’m aware,” Markson said.</p> <p><img width="466" height="262" src="http://cdn.newsapi.com.au/image/v1/edb2671b1a8fbc952a07b8274fc355bc" alt="The Michaelia Cash topic was rumour. Barnaby Joyce was fact, Sharri Markson said. Picture: ABC" style="display: block; margin-left: auto; margin-right: auto;"/></p> <p>“In the other instance, you had the Deputy PM of the country ... who has conservative family values, has campaigned against same-sex marriage, has campaigned against a vaccine because it might make women more promiscuous, a Deputy PM who has left his wife and four daughters for a media adviser who is now pregnant.</p> <p>“Not only that, but then authorised, so he signed off on the creation of new jobs for her with two politicians within his own party. While living for six months in a free rental from a National Party donor. The two things couldn’t be more different.”</p> <p>Markson said added, “when he was Deputy PM, deserved every ounce of scrutiny that we in the media apply to him. His family didn’t and we were very respectful to his wife and his four daughters. We never once hassled them”.</p> <p>“In that role he deserved every ounce of scrutiny and politicians, when they go into this job, they know they need to be accountable to voters,” she said.</p> <blockquote class="twitter-tweet"> <p dir="ltr">Why did Mr Joyce not deserve a level of privacy? <a href="https://twitter.com/SharriMarkson?ref_src=twsrc%5Etfw">@SharriMarkson</a> &amp; <a href="https://twitter.com/kamilashamsie?ref_src=twsrc%5Etfw">@kamilashamsie</a> respond <a href="https://twitter.com/hashtag/QandA?src=hash&amp;ref_src=twsrc%5Etfw">#QandA</a> <a href="https://t.co/hpryFT6hOP">pic.twitter.com/hpryFT6hOP</a></p> — ABC Q&amp;A (@QandA) <a href="https://twitter.com/QandA/status/970615143204704257?ref_src=twsrc%5Etfw">March 5, 2018</a></blockquote> <p>Shamsie observed the scrutiny was fair game “if you’re going to make a big deal about being all ‘family values’, then you’re setting yourself up for someone to come at you”.</p> <p>“It’s very striking to me that in Britain Jeremy Corbyn’s wife is never seen with him. They made a conscious effort that he’s not going to do that. He’s not going to use his marriage or wife, she will not hold his hand or make tea for interviewers or do anything of that sort.</p> <p>“So if someone is doing that, if they’re putting themselves forward in that way, then I’m afraid they are opening themselves up and their private life to scrutiny.”</p> <p>Host Tony Jones asked now that Joyce has stepped down, is it time to leave him alone.</p> <p>Plibersek said while people have a right to their private lives, “they don’t have a right to spend taxpayers’ money in any way they choose without accounting for it. They don’t have a right to fail to disclose gifts from donors, That’s our [the Labor Party’s] only interest.</p> <p>“The Labor Party has not been interested in his personal life. I feel sorry for everybody involved,” she added, suggesting that Joyce might want to stop giving interviews.</p>

How this Aussie couple reduced their electricity bill to $3.79

<p>As families across Australia <a href="http://www.oversixty.com.au/finance/retirement-income/2017/09/aussies-set-to-receive-another-power-bill-shock/" target="_blank"><span style="text-decoration: underline;"><strong>brace themselves for another hefty power bill</strong></span></a>, one Aussie couple has revealed how they reduced their electricity costs to less than $5 a month.</p> <p>David Kidd and his wife Jenny paid just $3.79 for electricity in the month of September. For less than a cup of coffee in some major cities, they were able to <a href="http://www.oversixty.com.au/finance/retirement-income/2017/10/energy-bills-drop-under-new-plan/" target="_blank"><span style="text-decoration: underline;"><strong>meet their daily power needs</strong></span></a>. But how did the Northern NSW couple manage this feat?</p> <p>Well, it all comes down to the solar panels on the roof of their two-storey home.</p> <p><a href="http://www.news.com.au" target="_blank"><strong><span style="text-decoration: underline;"><em>News.com.au</em> </span></strong></a>reports the Kidds fitted the panels to the east side of their home in August with a goal to get their bills as close to zero as possible. And it’s working.</p> <p>“It feels great to be able to provide the bulk of our electricity needs from our own installation with the grid only as a backup for longer periods of cloudy weather,” Mr Kidd, 64, said.</p> <p>“We are finding that, even on days of long cloudy periods, we can largely supply our needs.”</p> <p>The Kidds already has a small existing solar system, and recently added extra panels and a battery, at a cost of $12,500. But the shift saw an immediate drop in their bills.</p> <p>“Without any solar, my bills were up over $200 per month,” he said.</p> <p>“With my small system, the bills were $120 a month, but when the new solar and battery system was installed in late August, my September bill immediately dropped to $3.79.</p> <p>“The benefits were instantaneous."</p> <p>While it will take a few years for the Kidds to recoup the cost of their investment, they feel as though they’ve made the right choice, especially as power bills continue to spike.</p> <p>“Solar is easy to install and integrate, provides whatever degree of energy independence you wish to achieve and can afford — it takes away the worry of what your energy bill will look like each quarter and provides insurance against future electricity price rises,” Kidd says.</p> <p>“For me, solar is a no brainer. It’s clean, cheap and sustainable.”</p> <p>Have you considered solar panel as an option? What do you think is the right approach to tackle the rising power costs?
