I'm not pushing for the implementation of unproven technology. 26 years is the best number with the current data, making guesses about future demand or future supply is simply speculation. It does NOT matter whether or not the law or any other factor will allow you to confirm or deny your speculation it is still ONLY speculation.
Now we agree on the major point that the US needs to develop new forms of energy, however I don't think you understand the massive task that involves. The entire global economy is structured around energy and oil makes up a massive part of that, 26 years in my opinion is NOT a safe net to simply ASSUME and SPECULATE that new technologies will emerge in that time which will remove our need for oil.
What I'm saying is that those US reserves need to be used sparingly over time so as to give us the greatest amount of time possible to develop those new technologies. Thats the reasonable course of action.
