The idea of an “artificial leaf” sounds simple enough: Take a small, cheap, light-collecting device the size of a typical leaf, dunk it in a quart of water, and use solar energy to generate enough hydrogen gas for powering a small fuel cell.[read more]

military microgrid?

Never-fail military microgrids are breaking new ground in distributed energy management. Now one of them is getting connected to the grid at large.[read more]
