Cheap Hydrogen

NextJoule appears to have bright and gaseous future. www.nextjoule.com The company has invented a method for creating hydrogen that uses a silicon nanocrystal to capture sunlight and split water into hydrogen and oxygen. The cost of production is approximately the same as petroleum. Using photocatalytic decomposition of water

I believe that if we take the society cost of petroleum into account, the cost of NextJoule's solution is a fraction of the cost of petroleum. Hydrogen is renewable, safe, and produces only water vapor as a by product of combustion.
