2020-11-11 Redox Flow W/O Vanadium; Chinese Anti-Capitalism Economics

Researchers have come up with a redox flow battery that uses organic chemicals in place of toxic and expensive vanadium. They cost less than half as much, too. We need to have millions of these made and deployed over the whole world to solve the intermittent renewables problem. Chinese Anti-capitalist economics The capitalist way
