Tesla's 'Tiny House' roadshow demystifies its energy tech
Renewable energy is good for the planet, but it can be great for consumers -- depending on your location, you can actually make a profit using solar panels and backup battery storage. Those benefits can be hard for consumers to grok, however, so Tesla has launched the "Tiny House" tour in Australia with all of its latest technology in tow (literally).
IKEA’s selling home storage batteries for its solar panels
A rooftop of solar panels generating clean energy is great and all, but having somewhere to squirrel away that free juice is even better. After stepping into the shade for a good few months, IKEA began selling solar panels again last year with new teammate Solarcentury (a company that specialises in solar stuff). Today, the meatball-mad retailer is adding another piece of the off-grid puzzle to its shelves: A home storage battery.
Strong winds and clear skies help set UK renewable energy record
This week saw more milestones for renewable energy after the National Grid confirmed that power from green sources supplied more than half of UK energy for the first time. On Wednesday lunchtime, power from solar, wind, hydro and biomass accounted for 50.7 percent of energy production. In another UK first, nuclear, wind and solar each generated more electricity than coal and gas combined.
Mercedes-Benz and Vivint want to power your solar home
Tesla has been dominating home energy headlines in recent months, what with the release of its solar roof panels and residential batteries, but Elon Musk's company isn't the only one getting into the home energy game. Mercedez-Benz announced on Thursday that it is teaming with solar-energy company Vivint to develop an all-in-one solar/battery setup of its own.
Tesla ends SolarCity's door-to-door sales pitches
Tesla is used to selling cars online, but that's not how the recently acquired SolarCity liked to roll -- it preferred door-to-door sales pitches to get panels on your roof. Thankfully, you won't have anyone interrupting dinner going forward. Tesla has revealed that its solar energy division will stop those door-to-door sales in favor of internet and retail operations. It's what "most of our prospective customers prefer," the company says, and the other sales channels should more than make up for the loss. That will shake up jobs, but the roughly 1,000 people affected will either be moved to other sales methods or get a chance to interview for other positions at Tesla.
Tesla's app now reflects the company's move beyond cars
By merging Tesla and Solarcity, Elon Musk has sought about creating an "end-to-end clean energy" solution that starts in the home and extends onto the road. The idea is simple: harness solar energy via photovoltaic cell-embedded rooftop panels, store it in giant batteries and then pipe it into the home or an electric vehicle. As it stands, Musk's goal is on its way to being realized, but Tesla first needs to combine those individual components into one, and it's starting with software.
Coal company plans Kentucky's biggest solar farm for old mine site
Amid the decline of coal power, one fossil fuel company is refurbishing one of its old strip mining sites as a solar farm. Berkeley Energy Group is setting up two sites in eastern Kentucky as test locations to see if the concept is feasible. Early estimates peg the farm's production at 50 to 100 megawatts, which would yield five to ten times more electricity than the largest existing solar facility in the state.
Tesla's sleek solar panels are easier to install on your roof
Tesla's home energy efforts might be centered around its solar roofs, but it knows that not everyone can (or wants to) rip up their roof just to bring renewable energy to their home. To that end, the company is offering a first glimpse at Panasonic-made solar panels that would go on top of your existing roof. Unlike many aftermarket options, this would be relatively slick and unintrusive -- the panels have "integrated front skirts and no visible mounting hardware." While it'll be patently obvious that you have solar energy on your roof, it shouldn't be the eyesore you sometimes get with conventional designs.
Tesla starts taking solar roof orders next month
Compared to successfully launching a private rocketry business and an electric vehicle brand, Elon Musk's quest to line your roof with solar cells is a less flashy endeavor. He pitched it last August as Tesla's preamble in its eventually successful attempt to acquire SolarCity, a part of his greater goal to wean society off fossil fuel dependence. We haven't heard much else about it since. But in typical fashion for his announcements -- that is, in a tweet responding to a random question -- Musk told the world that folks can start placing orders for solar roofs in April.
German researchers built a molecule-splitting artificial sun
Scientists from the German Aerospace Center (DLR) are testing a novel way to generate hydrogen, a potential green energy source, by using a massive array of lights normally found in movie theaters.
Researchers break efficiency record for consumer-friendly solar panels
Turning sunlight into power is a surprisingly tricky thing. Experiments in academia have created solar arrays that can capture up to 40-percent of the sun's energy and convert it to electricity, but consumer cells are notably less efficient. At best, silicon-based technology has a theoretical 29-percent efficiency ceiling -- meaning any consumer panel in the low 20s is doing pretty well. Still, we're inching ever closer to the technology's limit. Researchers at Kaneko corp recently announced that they've developed a silicon solar cell with a record-breaking 26.3 percent efficiency rating.
SolSol's baseball hat can charge your phone using solar power
Solar technology is still far from becoming ordinary, but we're seeing more and more of it make its way to consumer products. And now that includes hats. SolSol, a startup from Los Angeles, made a baseball cap that has a small solar panel built into its brim. You can use it to charge your smartphone, tablet or any other device that needs to be plugged in via USB. It looks kind of odd to have a cable hanging down from your head, but the hat could come in handy if your gadget's battery is running low and there are no other outlets nearby.
After Math: Keep pace in the space race
It's been a productive week for those of us trying to get the hell off this crazy planet. NASA showed off a radiation-proof flight vest for interplanetary astronauts while Blue Origin debuted its latest rocket engine and previewed its upcoming New Glenn spacecraft. We also take a look at a solar farm visible from the ISS and examine just how badly the Trump regime is gutting NASA's Earth Science programs. Numbers, because how else will we know when it's time to blast off?
Solar-powered drone switches from helicopter to plane mode
Ever since the wobbly autogyro went out of fashion, engineers have tried designing a craft that gets the vertical lift of a helicopter's blades with the horizontal thrust of a plane is difficult to pull off. Popular successes, like the AV-8 Harrier series and V-22 Osprey, angle thrust down for takeoff and behind during flight. Researchers at the University of Minnesota in Minneapolis are building a drone that similarly transforms and is stocked with solar panels to prolong its deployment.
China is now the biggest producer of solar power
You probably don't think of China as a clean energy champion given its frequent problems with smog and continued dependence on coal power, but you may have to rethink your views after today. The country's National Energy Administration has revealed that its solar power production more than doubled in 2016, hitting 77.42 gigawatts by the end of the year. The country is now the world's biggest generator of solar-based electricity in terms of capacity -- it doesn't compare as well relative to population (Germany, Japan and the US could easily beat it), but that's no mean feat for any nation.
Europe's space agency plans to launch a space-weather satellite
A few years from now, we might have the power to make more accurate space weather forecasts thanks to an ESA satellite. The European Space Agency plans to launch a solar-monitoring space weather probe in 2023 to keep an eye out for Coronal Mass Ejections (CME), and it's hoping to send it to a stable orbit called the Lagrange point 5. That location will give the satellite a unique side-on view of the surface of the sun that's bound to face Earth in four to five days.
Alphabet dropped its plan for solar-powered internet drones
Wondering what happened to Google's solar internet drone project? Unfortunately, we don't have good news. An Alphabet spokesperson has confirmed to 9to5Google that its X division quietly dropped the Titan project shortly after it folded into X in late 2015. It won't surprise you as to why: Project Loon's high-altitude balloons are a "much more promising" way of getting people online in remote locations, the company says. Staffers who were working on Titan have found their way into other "high flying" initiatives, such as Project Loon and Project Wing. You can read the full statement below.
Half of UK electricity now comes from nuclear and renewables
A record 50 percent of the UK's electricity was generated from renewables and other low carbon energy sources in the third quarter of 2016. That's up from 45.3 percent the year prior, a milestone fuelled by a sizeable increase in wind, solar and nuclear energy. A neat quarter came from renewables, including hydroelectric, while the other 25 percent was sourced from nuclear reactors. According to the UK government, the growth in green energy can be attributed, at least in part, to "improved weather conditions" across the UK, including higher wind speeds, increased rainfall and longer stretches of sunlight (though I don't remember that last one happening).
A French town just installed the world's first 'solar road'
The tiny town of Tourouvre-au-Perche in Normandy, France no longer has to worry about how it will power its street lights. The Sun will handle that.
Tesla's master plan was realized in 2016
Tesla started in 2006 as a niche electric sports car manufacturer. Its 2008 Roadster had an insane range of 244 miles and an equally bonkers price of more than $100,000. It was the first step in CEO Elon Musk's 2006 master plan to eventually bring a high-range, reasonably priced EV to the masses. Ten years later, that strategy is finally about to pay off.
