Hydrogen: Alternative Energy Breakthrough
Sounds good. I wonder if it could also be developed to produce fresh water, or get fresh water from salt water? - Since we seem to not only be on a path to run out of oil and other fossil fuels, but run out of water as well.

Scientists: Alloy will Revolutionize Energy by Generating Hydrogen on the Cheap
The finding shows that an alloy formed by a 2 percent substitution of antimony (Sb) in gallium nitride (GaN) has the right electrical properties to enable solar energy to split water molecules into hydrogen and oxygen. "When the alloy is immersed in water and exposed to sunlight, the chemical bond between the hydrogen and oxygen molecules in water is broken. The hydrogen can then be collected," reported the Science Daily.
Hydrogen's potential utility in green tech initiatives is immense. It can be used to generate electricity, produce heat and run vehicles. It also has wide-ranging applications in science and industry. "When combusted, hydrogen combines with oxygen to form water vapor as its only waste product," the report points out.
"Hydrogen production now involves a large amount of CO2 emissions ... Once this alloy material is widely available, it could conceivably be used to make zero-emissions fuel for powering homes and cars and to heat homes," said Sunkara.
