There seems to be issues with whether the windfall profits of oil companies should be taxed, the concern is that the market is better suited to fund R&D and that it would raise prices on gas as companies passed the tax, to the second I say good, we should be promoting higher prices to force conservation and to the first I say no, I think the problem is that the market will always fund what is marketable and profitable, not always what will net future benefits, in this case the government is best to start the research, and once it seems like the market can make profits on it let them take over or join the research.
