perhaps you could offer some specific rebuttals to the argument. no new business is going to invest in a sector where they cannot determine the price point for their new product, based on what established technology in that sector charge. its not going to happen, it isn't happening now in the energy sector (for oil alternatives) - the only energy initiatives are small scale, or are already government funded trial projects.
anyone who thinks that there is going to be huge private investment to develop oil alternatives, based on the current price of oil, is dreaming. its not going to happen, the price is too volatile and the market is being whipsawed by speculative excesses.
