Of course, we know that the oil companies bought up all - or most - of the patents for anything that looked promising, therefore we will still be under the same masters. The Patenting laws must be modified (or abolished) before any real progress can be made. Until power production is made public domain, the BIG BOYS will still hold the power. The rest does not need to be said, we are already experiencing it now. It is a lesson to all - if you have a good idea (particularly in the energy field), TELL NO-ONE, ESPECIALLY THE OIL COMPANIES, just make it, copyright it, mass produce it and make millions. But for the planet's sake DON'T Patent it, let others add their bits and make it PUBLIC DOMAIN!
