The World’s First Sand Battery Debuts in Finland

As fossil-fuel-derived energy systems facilitate the degradation of the planet, researchers have been innovating alternative and sustainable solutions—including the world’s first sand battery from Finnish startup Polar Night Energy. Currently operating in Finland’s Kankaanpää district, the battery relies on a large steel tank full of regular, dry sand with a heat exchanger buried in the middle. When the sand is heated, the tank can store …

Experimental Nuclear Fusion Reactor Proves Limitless, Clean Power Is Possible

Curbing climate change means finding a near-limitless, zero-carbon power source. To do that scientists have often turned to nuclear fusion—the process of fusing two or more atoms together, which releases massive amounts of energy (and is also the process that makes the sun and stars shine). But while scientists have been able to generate this energy before, they haven’t been able to sustain it for …

Tasmanian Island to Harness Energy From Waves

The waters around King Island (in the Bass Strait off of Tasmania, Australia) will host a new technological unit that features an artificial “blowhole” to capture energy from the movement of waves. Funded by federal grants and private investors, this Wave Swell Energy renewable resource experiment will provide data about the system’s potential for expansion to nearby areas with adequate swells. Current research estimates that …
