ElectricSteve writes: FUKAI Environmental Research Institute has announced a new technology for obtaining hydrogen that it claims is less expensive and more efficient than anything that's been tried so far. FUKAI's process involves adding aluminum or magnesium to boiling "oefunctional water," a proprietary substance that can be produced simply by running regular tap water through a natural mineral-containing "functional water generation unit." The bonds that join hydrogen and oxygen molecules in regular water, which ordinarily require some energy to break, are weakened in functional water. The liquid yields 2 liters (122 cubic inches) of hydrogen gas per gram of aluminum, or 3.3 liters (201 cubic inches) per gram of magnesium. FUKAI claims that the cost of producing enough hydrogen to generate 1kWh of electricity is about 18 cents US. That cost could be lowered through the use of recycled aluminum.
