Storing clean energy to use later poses a challenge in regions that have long stretches with low wind and sunlight, stressing power grids fed by renewable sources. Augwind Energy believes it's found a solution thousands of feet below the ground.

Around this time last year, Yaber launched two portable 1080p projectors designed to provide entertainment on outdoor adventures. They both required a dongle to access Google TV, but the company has now rectified that with the T2 Plus GTV edition.

In an effort to reduce the use of precious land to build renewable energy storage facilities, the Fraunhofer Institute has been cooking up a wild but plausible idea: dropping concrete storage spheres down to the depths of our oceans.

Adding new meaning to the term "fusion cuisine," robot science and gastronomy united to create an elaborate cake that features edible components and the world's first edible rechargeable battery. (Well, it's rechargeable until you eat it.)

As it starts to get a little warmer in the Northern Hemisphere, you might be looking to the yard for movie nights. Many portable projectors still need to be plugged in, but Dangbei's Freedo caters for cable-free watching for up to 2.5 hours.

Researchers at Korea's Daegu Gyeongbuk Institute of Science & Technology have created a nuclear battery that could turn radiation directly into electricity for decades – but without all the scary stuff associated with nuclear radiation.

Elecom has launched the world's first power bank to feature a sodium-ion battery inside. It promises significantly longer cycle life than traditional lithium-ion batteries, as well as the ability to operate in extremely hot and cold climes.

Just because a mine has been exhausted of its ore, that doesn't necessarily mean it has no value. A 2023 study suggests that the shafts of such abandoned mines could serve as energy-storing gravity batteries.

BMW has been slowly dropping breadcrumbs about its upcoming Neue Klasse range of EVs over the last several weeks, and the latest teaser reveals nifty range-extending battery tech. Expect 30% longer range, quicker charging, and bidirectional charging.

Flint believes it has the formula for the most sustainable battery the world has ever seen, capable of seamlessly replacing lithium for many applications. The chemistry of plant cellulose and other renewables promises a density over 220 Wh/kg.

Chinese energy giant BYD has just inked a deal to build the largest battery storage projects on the planet for Saudi Arabia. The company will put together facilities at five sites totaling a massive 12.5 GWh of energy storage.

The electrification expansion continues as Suzuki takes its first steps toward its very own electric future with the e-Address electric scooter. With a 54-mile range, it comes with most of the bells and whistles you'd expect on an urban commuter.
