Non-toxic and scalable water-based flow batteries would be a good solution for storing renewable energy in urban areas - if it weren't for their very low energy density. Researchers want to remedy the situation with clever materials design.
Researchers have designed micromotors that move around on their own to purify wastewater. The process creates ammonia, which can serve as a green energy source. With a new AI method they plan to tune the motors to achieve the best possible results.
