The 21st century can and must be marked by the world's transition to nuclear fusion energy. It is, contrary to prevailing "wisdom," the only currently available solution. Specifically: a complete energy solution that uses existing (or doable) particle accelerator technology to ignite, contain and harvest the energy from clean and safe nuclear fusion explosions, and produces vast amounts of low cost energy and energy products.
I'm not asking anyone to believe any of this; not right away. The scientific evidence is there, as strong as ever (though a bit faded and dusty from 34 years of neglect) and it will come out eventually -- starting now, if I can help it. Though it may seem too radical or too big (given the size of our problems, how can any solution be too big?), the science clearly points to this technological approach as "the best bet" for near-term fusion energy.
Note: I believe that the scientific evidence also makes a strong case that this technology will produce highly economical energy, and will quickly establish itself --globally -- as the new baseload source of electricity and liquid fuels. If I didn't believe this, then I wouldn't bother with it in the first place; for I reject the notion that a combination of expensive energy technologies can somehow solve our problems -- no matter how "green" they appear on the surface. A true energy solution must be environmentally sustainable, but it must also create real wealth -- tangible, material, renewing, rejuvenating wealth -- on a scale that raises living standards throughout the world, allowing all of us to benefit from what modern technology and "civilization" have to offer.
Paraphrasing Churchill, I believe we Americans will finally do the right thing -- having tried everything else.
