It would be a dull month if a new rechargeable battery project didn’t make headlines amid all the excitement surrounding electric cars. This month’s indisputable winner is the lithium-ion battery that replaces cobalt with iron, and-rather surprisingly-works, at least according to the people who came up with the idea.
Fisker has launched its Emotion electric luxury saloon at the Consumer Electronics Show in Las Vegas – and there’s a vegan option. The long-awaited Tesla rival, with eye-catching looks and dramatic ‘butterfly’ doors, has a non-animal interior available for those who don’t want the premium leather interior of the show car.
“When faced with Magnic Light for the first time, many believe that this is either a fake or a perpetual motion generator,” inventor Dirk Strothmann told Digital Trends. “Both aren’t true, but the underlying eddy current technology is so fascinating because the magnetic fields only appear when there is motion
Electric eels generate voltage through long stacks of thin cells that run end-on-end through their bodies. Called electrocytes, these cells create electricity by allowing sodium ions to rush into one end and potassium ions out the other, all at the same time.
Graphene. You know may know it as that wonder material that promises to change the way we build roads, craft smartphone screens, kill bacteria or even keep our feet cool. Composed of a one-atom thick sheet of carbon, graphene is thin and highly flexibility, strength and chemical stability. It also conducts electricity 100 times more effectively than copper and moves electrons 140 times faster than silicon (good for fast-charging).
“Magnesium is such a new technology, it doesn’t have any good liquid electrolytes,” says Gerbrand Ceder, co-author of a paper describing the new device. “We thought, why not leapfrog and make a solid-state electrolyte?”
