Technology + Ethics Behind Turning Trees into Power Generators

In its earliest stages, and developed by graduate students from Keio University in Tokyo, the “biological microgrid” Raiki will aim to harvest electricity from trees by drawing from the “triboelectric” effect in foliage. This is a phenomenon of movement, much like static electricity, generated when positively charged leaves come into contact with negatively charged materials (like a tree trunk). Industrial designer Catalina Lotero explained this …

Putting excess London Underground heat to use, an app for analog photography, a 2,000-year-old sarcophagus and more

NASA’s Highest-Resolution Photo of Mars NASA’s new image of the surface of Mars—the space agency’s highest-resolution photograph of the Red Planet ever—comprises 1,200 total images. The wide-pan photograph features what researchers hypothesize are former sites of lakes and streams that dried up over the course of several billion years. The 1.8-billion-pixel shot was taken by the Curiosity Rover during November and December of 2019 and …

A Nuclear Reactor For The Future

As current nuclear plants grow outdated, researchers, founders, and developers eye the energy source’s inevitable evolution. Most notably, the next generation of nuclear reactors will be smaller—almost 1/100th the size of current models. One specific advancement, named the NuScale reactor, could be grouped in clusters and sealed within some sort of protective container to prevent the spread of nuclear waste should an accident occur. Perhaps …
