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.

Rolls-Royce gave us a glimpse of the nuclear future of next-generation spacecraft and Moon bases when it unveiled a mock-up of its Space Micro-Reactor Concept Model at the UK Space Conference in Belfast, which ran between November 21 to 31, 2023.

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.
-
Adoption of wireless charging has been fairly slow, but it could pick up if it worked over longer distances. Now Aalto University engineers have developed a new system that can allow more efficient wireless power transmission over longer distances.
-
As anyone who's ever seen a bolt of lightning knows, the air around us can be filled with an astonishing amount of energy. A new study shows a way to harvest this power using a perforated nanofilm that can be made from a vast variety of materials.

Sleeping on a cliff face is one way to soak up the great outdoors, but most of us like a little comfort at the campsite. That's why portable power stations are such a great piece of kit. We've been putting Bluetti's latest offering to the test.
-
Researchers have developed a tiny battery that could be stored up to 100 years before being activated. The secret lies in sealing up dormant bacteria until it's time for them to be called into power-generating service.
-
Korean engineers have demonstrated a new system that uses infrared lasers to beam power over distances as far as 100 ft (30 m), which could eventually lead to technology that automatically charges your phone as soon as you walk into a room.
-
The first generation-IV nuclear reactor design has been approved for certification by the US Nuclear Regulatory Commission. NuScale's small modular reactor design promises safe, clean energy at radically reduced cost, land use and installation time.
