Solar Paint Could Be a Big Step in the Race to Replace Carbon-Based Fuels

Researchers in Australia have developed a paint for roofs and other surfaces that turns moisture in the air into hydrogen, a sustainable form of energy.

H H ydrogen cars emit water vapor as exhaust rather than pollutants that warm the planet and compromise human health. But the cost and energy to make hydrogen has long undercut efforts to include it among solar, wind, and other green power sources.
