Toward a low-cost 'artificial leaf' that produces clean hydrogen fuel

Toward a low-cost 'artificial leaf' that produces clean hydrogen fuel

For years, scientists have been pursuing "artificial leaf" technology, a green approach to making hydrogen fuel that copies plants' ability to convert sunlight into a form of energy they can use. Now, one team reports progress toward a stand-alone system that lends itself to large-scale, low-cost production. They describe their nanowire mesh design in the journal  ... Read more »

Thermoelectric power plants could offer economically competitive renewable energy-

thermoelectric power plants

A thermoelectric power plant might use energy harvested from ocean waves to pump cold water up through a heat exchanger/generator near the surface. The heat exchanger is made of thermoelectric materials which can use the temperature gradient between the warm and cold water to generate electricity.
