First, build that star wars...although I would not limit it to space based just yet, I think some ground based (especially theater level) components are still worth further exploring.
Second, regardless of Caruba's credentials or lack thereof, he is raising a legitimate issue, that Hydrogen is not a cure all for dependence on oil. There are not vast underground reserves of hydrogen waiting to be discovered and exploited. It will take energy to make the H2. And that energy will have to come from somewhere. And we ain't been building nuke plants and hydro dams.

that Hydrogen is not a cure all for dependence on oil

Probably not. But Anything that gets us out of NutLand is worth looking into. Even the current Energy Secretary is on board with that one. And even if it CAN'T be done effectively....shhhh. Don't tell the Arabs. They'll think we can do it, and maybe start to clean up their act.

In the 1970's, when OPEC was roaring, Luis Echeverria, the President of Mexico, warned OPEC that "the Americans will create a technological solution" to get off of oil if they (OPEC) raised the price too high. It doesn't matter if he was right, wrong, or just scared. If it influenced their cartel's behavior positively...mission accomplished.

I guess we can't tell them about our Zero-Point Energy Motorcycles yet...
