Los Angeles Power and Water officials have struck a deal on the largest and cheapest solar + battery-storage project in the world, at prices that leave fossil fuels in the dust and may relegate nuclear power to the dustbin.

Later this month the LA Board of Water and Power Commissioners is expected to approve a 25-year contract that will serve 7 percent of the city’s electricity demand at 1.997¢/kwh for solar energy and 1.3¢ for power from batteries.

“This is the lowest solar-photovoltaic price in the United States,” said James Barner, the agency’s manager for strategic initiatives, “and it is the largest and lowest-cost solar and high-capacity battery-storage project in the U.S. and we believe in the world today. So this is, I believe, truly revolutionary in the industry.”

Nanosized robots capable of crawling around on a person’s brain or underneath the skin may sound like a nightmare to some, but researchers suggest the mini machines could serve medical purposes such as gathering data on the brain or the spinal column.

Researchers at the University of Pennsylvania and Cornell University recently announced they have built nanosized, solar-powered robots made from silicon. One million such robots can fit on a 4-inch silicon wafer. “These robots are built massively in parallel, so I don’t build just one robot, I build a million robots, which is awesome,” declares Marc Miskin, an assistant professor of electrical and systems engineering at the University of Pennsylvania.

The microscopic machines can carry up to 30 times their own weight, travel at about the speed of biological cells, survive temperatures up to 400 degrees, live unscathed in battery acid or other harsh chemicals, and can be injected with a hypodermic needle.

Oil spill cleanup technology is a surprisingly innovative field—we learned as much in the wake of the BP Gulf disaster, when everyone from conservation biologists to barbers to Kevin Costner rushed to sell the government on their wild, sometimes literally hairy oil-sucking solutions. We had rubber goop that turned oil solid, massive bags of hair, and MIT’s previous entry into the cleanup fray, robotic oil-eating submarines.

But now the renowned science lab has a better idea: nano-magnets.

MIT researchers have developed a new technique for magnetically separating oil and water that could be used to clean up oil spills. They believe that, with their technique, the oil could be recovered for use, offsetting much of the cost of cleanup.

One of the coolest electric conversions we have ever seen, an old-school VW Bug powered by Tesla batteries, is being given away for a good cause.

Zelectric, a California-based company specializing in electric conversion, has equipped a 1958 VW Bug with their conversion kit, including an electric motor and Tesla battery modules.

Condensation might ruin a wood coffee table or fog up glasses when entering a warm building on a winter day, but it’s not all inconveniences; the condensation and evaporation cycle has important applications.

Water can be harvested from “thin air,” or separated from salt in desalination plants by way of condensation. Due to the fact condensing droplets take heat with them when they evaporate, it’s also part of the cooling process in the industrial and high-powered computing arenas. Yet when researchers took a look at the newest method of condensation, they saw something strange: When a special type of surface is covered in a thin layer of oil, condensed water droplets seemed to be randomly flying across the surface at high velocities, merging with larger droplets, in patterns not caused by gravity.

“They’re so far apart, in terms of their own, relative dimensions”—the droplets have a diameter smaller than 50 micrometers—” and yet they’re getting pulled, and moving at really high velocities,” said Patricia Weisensee, assistant professor of mechanical engineering & materials science in the McKelvey School of Engineering at Washington University in St. Louis.

Fish are an important part of the ecosystem and the human diet. Unfortunately, overfishing has depleted many fish stocks, and the proposed solution — fish farming — is creating far more problems than it solves. Not only are fish farms polluting the aquatic environment and spreading disease to wild fish, farmed fish are also an inferior food source, in part by providing fewer healthy nutrients; and in part by containing more toxins, which readily accumulate in fat.

Farmed Salmon = Most Toxic Food in the World

Salmon is perhaps the most prominent example of how fish farming has led us astray. Food testing reveals farmed salmon is one of the most toxic foods in the world, having more in common with junk food than health food. Studies highlighting the seriousness of the problem include:
