i am less optimistic about hot fusion. just last year they delayed the decision in which country (france or japan) to build the testreactor. ofcourse the america bashers immediately accused the usa of trying to punish france for being against the iraqwar by arguing for japan. the testreactor will need more power than it produces, cost all nations on the project billions of dollars and it is not yet clear how the plasmachamber is effected by radiation. even if they succeed in building fusion powerplants, we are still a long way from using it in cars.
but who knows, maybe this weekend someone will discover a catalyst for cold fusion. the future is promising.
