Purdue professor on the "aluminum enabling hydrogen economy"
There is a 26-minute online presentation of the gallium-aluminum technology available here. Woodall says that the reaction of aluminum with water has the same energy content per unit weight of oil, about 20,000 BTUs or about 6 kWh per pound. And, since aluminum is safe and plentiful, it has high potential to create "aluminum enabling hydrogen economy" (click forward to slide 10 of 20 for Woodall's explanations about using gallium to disrupt the passivating oxide process).
