Actually, they should be antimatter-powered... and probably will be. We are not that far from practical (although costly) antimatter rockets. The technology won't be very useful for power plants, since antimatter production is horrendously inefficient. But for applications where the energy/mass ratio is critical, i.e. starships, fusion isn't even close. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
