If you've ever had a packing peanut stick to your clothes as you unbox your Amazon delivery, then you know that Styrofoam is pretty good at generating static electricity. A new invention turns that quality into a workable energy-saving solution.

Scientists in Japan have developed a new organic device that can harvest energy from heat. Unlike other thermoelectric generators, this one works at room temperature without a heat gradient.

Honeybee Robotics has outlined a plan to build a kind of power grid on the Moon, with a network of Statue of Liberty-sized towers containing solar panels and batteries that provide power and communications, and even act as streetlights.

MIT scientists have discovered an intriguing new way to produce hydrogen fuel, using just soda cans, seawater and coffee grounds. The team says the chemical reaction could power engines or fuel cells in marine vehicles that suck in seawater.

Deep-tech startup Sinonus is working to commercialize a groundbreaking new breed of multifunctional carbon fiber. In its vision, the wonder-composite will serve as a structural battery for everything from electric aircraft to windmills.

Water can hold a huge amount of thermal energy, and a new system to tap into this is being trialed in Scotland. A startup called SeaWarm uses heat stored in bodies of water for buildings, pulling four times more heat out than electricity used.

The Princeton Plasma Physics Laboratory (PPPL) hits a new fusion reactor endurance record that could open the door to practical fusion power on a commercial scale. Using a tungsten lining, the WEST reactor held a reaction for six minutes.

Natron Energy fell a little behind schedule on production plans for its sodium batteries but officially commenced production of the rapid-charging, long-life lithium-free batteries this week, bringing to market an intriguing new storage alternative.

A new industrial-scale “sand battery” has been announced for Finland, packing 1 MW of power and a capacity of up to 100 MWh of thermal energy for use during those cold polar winters. The new battery will be 10 times bigger than a prior pilot plant.

A revolutionary alternative to conventional rockets that uses controlled explosions has completed its first long-duration engine test as part of Venus Aerospace's partnership with DARPA to develop a Rotating Detonation Rocket Engine.

There's enough natural hydrogen trapped underground to meet all projected demands for hundreds of years. An unpublished report by the US Geological Survey identifies it as a new primary resource, and fires the starter pistol on a new gold rush.

A potentially game-changing and largely unexplored energy jackpot lies beneath the ocean floor, according to a whitepaper from geoscience tech consultancy CGG. Unique conditions under the sea bed promise cheaper and more accessible geothermal power.
