Description Stellarators, twisty machines that house fusion reactions, rely on complex magnetic coils that are challenging to design and build. Now, a physicist at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has developed a mathematical technique to help simplify the design of the coils, making stellarators a potentially more cost-effective facility for producing fusion energy. “Our main result is that we came up with a new method of identifying the irregular magnetic fields produced by stellarator coils,” said physicist Caoxiang Zhu, lead author of a paper reporting the results in Nuclear Fusion. “This technique can let you know in advance which coil shapes and placements could harm the plasma’s magnetic confinement, promising a shorter construction time and reduced costs.” Fusion, the power that drives the sun and stars, is the fusing of light elements in the form of plasma — the hot, charged state of matter composed of free electrons and atomic nuclei — that generates massive amounts of energy. Twisty, cruller-shaped stellarators are an alternative to doughnut-shaped tokamaks that are more commonly used by scientists seeking to replicate fusion on Earth for a virtually inexhaustible supply of power to generate electricity. A key benefit of stellarators is their production of highly stable plasmas that are less liable to the damaging disruptions that tokamaks can incur. But the complexity of stellarator coils has been a factor holding back development of such facilities. The coils of a stellarator must be constructed and arranged around the vacuum chamber very precisely, since deviations from the best coil arrangement create bumps and wiggles in the magnetic field that degrade the magnetic confinement and allow the plasma to escape. These problematic magnetic fields can easily be caused by misplacement of the magnetic coils, so engineers stipulate strict tolerances for these components.

Description Walmart is suing Tesla over claims that the company’s solar panels caused fires at around seven of its stores. The blazes destroyed merchandise and caused other damage worth hundreds of thousands of dollars, Walmart claimed in a lawsuit filed in a New York court on Tuesday, August 20. Targeting Tesla Energy Operations — part of the larger company led by billionaire entrepreneur Elon Musk — Walmart’s lawsuit alleges a breach of contract “arising from years of gross negligence,” as well as “a failure to live up to industry standards” regarding the design, installation, and maintenance of the solar panels on the roofs of around 240 Walmart stores. The retail giant claimed that many of the issues “stemmed from a rushed, negligent approach to the systems’ installation” carried out from 2010 by SolarCity, the solar panel company founded by two cousins of Musk, and which Tesla acquired in 2016 for $2.6 billion. According to the filing, SolarCity’s business model meant that the solar panel systems were installed “haphazardly and as quickly as possible in order to turn a profit, and the contractors and subcontractors who performed the original installation work had not been properly hired, trained, and supervised.” Walmart claims that the personnel deployed by Tesla to maintain the solar systems “lacked basic solar training and knowledge,” and that some of the installed solar panels contained defects that were “visible to the naked eye or readily identifiable with the proper use of standard equipment.” The lawsuit says that the existence of the apparent defects suggested Tesla “had not been inspecting the sites or that its inspection protocols were woefully deficient.” The filing also describes “dangerous wire connection practices” and says Tesla failed to keep proper documentation regarding its work at Walmart sites. Walmart wants Tesla to remove its solar panels from all of its stores, and to pay for damage caused by the fires as well as other related costs. The lawsuit landed in the same week that Tesla launched a new solar-rental plan for homeowners in six states. We’ve reached out to Walmart and Tesla for comment on the case and will update this piece if we hear back.

Description Remember solar roads? Five years ago, the idea of building insanely expensive solar panels on the ground and driving pollution-spewing vehicles over them was all the rage. Scientists pointed out the obvious flaws. A flat surface that can’t tilt or move to capture sunlight doesn’t hit very high-efficiency targets. Driving pollution-spewing vehicles over the solar panels in question would inevitably hurt their ability to gather sunlight as pollution built up on the surface. Putting solar panels on the ground and then driving over them is an excellent way to smash said solar panels to flinders. In short, the grand push for solar roadways left a lot of very smart people wondering why we didn’t just put the same amount of money into building conventional solar panels and wiring them up in the normal fashion. Naysayers, all of them. The campaigns to build various solar-powered roads took off. The Dutch, at least, saw reason in one regard and deployed them as part of a bike path rather than attempting to craft a workable system from running pollution-spewing vehicles over a surface that gathers energy from sunlight. Now, some years after the first solar roads opened for business, they’re… well, an abysmal failure. According to French newspaper Le Monde, the roadway-building effort failed in part because the builders didn’t consider how robust the construction would actually need to be. The “Wattway,” as the French solar road installation is known, is disintegrating much more quickly than its builders anticipated. This is a fairly common issue. One reason the US highway system requires so much more maintenance than its builders ever anticipated is that the weight of the vehicles we’ve allowed to travel on the highways has increased so much. Roadway damage rises as the fourth power of axle weight, which means an 18,000-pound truck does 3,000 times more damage to the pavement than a 2,000-pound car. French vehicle weights are going to be different and farm tractors aren’t going to weigh as much as a semi. But the point stands: These roads weren’t built to the required standard, even though the manufacturer, Colas, promised that the resin would withstand the weight of 18-wheeler trucks.

Description If you’ve been trying to decide whether or not to purchase solar panels for your home, Tesla has a new way to entice you: Renting them. With solar rentals, Tesla says “customers get the best from solar power — clean, cheap energy to power homes and vehicles — without upfront costs or decades-long agreements. In fact, customers can get solar power with one click, instead of lengthy consultations and piles of paperwork.” The company is offering the option to rent solar panels in six states: Arizona, California, Connecticut, Massachusetts, New Jersey, and New Mexico. In order to participate, you need to be the homeowner and be a ratepayer with one of the specific utility companies Telsa is working with in your state. Rentals include the panels, as well as any other necessary hardware, installation, support, and maintenance costs. The company is offering the service in small, medium, and large sizes. A small system is 3.8 kilowatts, a medium system is 7.6 kW, and a large one is 11.4 kW. Monthly rental costs for a small system vary by state and range from $50 to $65 a month. Tesla also has some estimates on how much power those panels are expected to generate each year. Like all good deals, there is a catch: If you decide you don’t want to rent solar from Tesla anymore, you’ll be forced to pay a $1,500 removal fee to the company to take down the equipment. That fee can’t be waived. However, if you decide to sell your home you can transfer the monthly subscription to your home’s new owners, so you don’t have to remove the panels from your roof prior to the sale. Panels can be upgraded once you install them, but can not be downgraded unless you want to pay that $1,500 fee. Last year, Tesla started working with Panasonic on a new catalog of solar panels that blend into a customer’s roof, with no visible hardware. The panels were first announced in 2017, but were installed on their first roof in early 2018. Tesla’s solar panel rental program comes days after the company lowered the price of its solar panels, in some cases dropping the price per watt to as low was $1.75, 16% lower than the national average of $2.09.
