better hydrogen production through nanotechnology
The BBC reports on a solar-powered fuel cell that uses a special nanocrystalline metal oxide film to convert sunlight from across the entire spectrum into electricity, which is then used to crack Hydrogen from water. The current efficiency of the system is 8%; at 10% it becomes commercially viable.
"Using a 10% cell, we say that a seven-metre squared array will power a Mercedes A class car for 11,000 miles a year [in LA sunlight conditions] without going to power station."
