A company called AlumiFuel Power claims that it has created a more efficient means of generating hydrogen for fuel.
Michael Kanellos writes, "AlumiFuel says it can generate 1,000 liters of hydrogen in 20 minutes by mixing water with two 32-ounce cans of aluminum powder and other additives. The reaction between the water and the aluminum and chemical powders creates the hydrogen. (Aluminum has a strong urge to react with oxygen, which is why aluminum powder gets used as an accelerant in rocket fuel.) Carbon dioxide does not get produced in the reaction."
