What is the source of energy when water is added to alunimum and gallium alloys? We also do this with carbon rods in water. But that also does not make hydrogen energy.

Hydrogen could be manufactured and stored in large low pressure tanks. Energy stored for short term use that is useless for transportation - in essence a battery. Hydrogen is not a fuel. No viable technology exists even in theory to make it useful. So what technology with promise is GM working on? Notice how its top management - business school graduates - have thrown most all their eggs into one hydrogen basket. How many other technologies are therefore sitting stifled?

But again, its about doing more with less. Where are the programs to increase thermodynamic efficiencies in their piston engines. Or where are their programs to replace piston engines with something that is even more thermodynamically efficient? Government gives them millions of dollars in 1994 to build a hybrid? Eleven years later they still don't have a hybrid? What genius did that R&D?
