I think that the problems throughout Ca. and the rest of the world reguarding energy could be conquered by cold fusion. It has already been proven to work in electrolysis experamentation, and I think that particle exelerators could be a way to go. It may work in a similar way, as the positive and negetive particles collide they explode realesing energy. If the same acceloration was attempted on a smaller sized machine I believe that the particles could fuse and cause a similar type of energy. I know that it has never been proven that cold fusion exists, but on the other hand there is little evidence that says there isn't either. Many scientists of high accord have attempted to duplicate the experament, some were successful, others failed. Still there should be attempts to further research to find a definate answer.
