Power

Deep Fission has come up with a new solution to the economic and safety problems of nuclear power that is, to say the least, novel. The idea is to build a reactor that's under 30 inches (76 cm) wide and stick it down a mile-deep (1.6-km) drill shaft.

E Ink screens are not only kinder to your eyes, but offer great battery life due to their low power draw. But a new display from Digital View doesn't have a battery at all, and gets the juice it needs from an overhead Wi-Charge wireless power module.

Supercritical geothermal power holds the promise of meeting humanity's energy needs for millions of years, but how practical is it? A new analysis by Karthik Subramanian of Lux Research suggests that it may lie somewhere between improbable and impossible.

Wind Catching Systems has received an important tick of approval for its enormous 40-megawatt Windcatcher offshore floating wind turbine array, as it prepares to build a full size demonstrator project off the Norwegian coast.

Two 650-foot-tall towers have risen in China's Gansu Province. Combined with an array of 30,000 mirrors arranged in concentric circles, the new facility is expected to generate over 1.8 billion kilowatt-hours of electricity every year.

Just a year ago, Fervo Energy successfully demonstrated the effectiveness of its horizontally oriented geothermal system. Now the company has landed a massive contract for providing its clean, virtually endless power to the California grid.

Bill Gates has helped break ground to mark the construction of the first next-generation nuclear reactor in the United States. The joint project by TerraPower and the Department of Energy plans to build a sodium test reactor in Kemmerer, Wyoming by 2030.

Battery life wouldn't be an issue for drones if they could just recharge on power lines as needed. That's exactly what an experimental new quadcopter can now do, allowing it to stay aloft pretty much indefinitely.

China claims to have brought the world's first Gen IV commercial nuclear reactor online. The Shidao Bay Nuclear Power Plant HTR-PM high-temperature gas-cooled pebble-bed reactor in Shidao Bay, Shandong Province, reportedly went into service this month.

The world's largest and most advanced tokamak fusion reactor has gone online as the EU/Japanese 370-tonne JT-60SA reactor was fired up for the first time during an inauguration ceremony in Ibaraki Prefecture, Japan.

In a move that sounds like the wildest of science fiction, DARPA has announced its new Persistent Optical Wireless Energy Relay (POWER) program that plans to use lasers relayed by airborne platforms to power machines thousands of miles away.

Weaning the world off fossil fuels will take time, so finding ways to make energy generation more efficient is still important. A new coating for steam condenser pipes could, if rolled out widely, add more than a Russia’s worth of extra power per year.
