Definitely not. I would, however, agree to become a quadrapalegic for 10 years, if complete recovery was only 50% assured, if these conditions were met:
1) all oil and coal were removed from the planet immediately
2) every house on the planet would get 3,000 watts of solar panels
3) the U.S. government would spend half of the money they're spending daily in Iraq and Afghanistan on erecting 2-5 megawatt wind generators (that would buy ~100 MW/day)
4) every country on earth could have 1 fusion-powered nuclear power plant, for the days/parts of the country when/where it wasn't sunny, and the wind wasn't blowing
5) every automotive manufacturer on earth decided to make good, lightweight solar/electric automobiles
