QuoteIn a milestone toward sustainable energy, scientists devise a way to mimic the way leaves convert sunlight into fuel.
The leaf's ability to convert sunlight and water into storable fuel makes it the ultimate in solar energy. Now researchers say they have found a way to mimic this seemingly simple feat.
Interesting. If they can solve the gas separation issue at a reasonable cost this is another tick for a hydrogen economy.
