Yep,... they are just stabbing in the dark, the world is a lot more complex than the Boffins give credit for.

That should be do-able, when push comes to shove, short term. I believe is a project to be USA led, driven and put into place.

This certainly is doable unfortunately it seems as if the U.S. is not in any hurry or has any real motivation to pursue it at max speed. It's sad but I think only a major conflict/war would force the U.S. (and maybe the world altogether) to pursue research into seriously feasible oil alternatives. If you take a look at the major advances in technology in the U.S., most of them have come out of war. For example, the current War on Terror has driven technological advances in robotics to a whole new level in the U.S. The Cold War drew advances in avionics.

Yes, you are right. Necessity is the mother of invention. And that is where we are now.
