His original paper stated that it would require impossible amounts of negative energy, but that problem can be circumvented. It is experimentally proven that spinning niobium supraconductors cooled by liquid helium affects gravity (ESA: Towardsa new test of general relativity, 2005). Several scientific theories, including string theory, also predict that gravity and electromagnetism unify in higher dimensions. It is possible to make the gravitational effect much stronger by placing many spinning supraconductors close to each other. A continuous warp metric would have the advantage of creating no event horizon and thus no Hawking radiation, thanks to many slower than light warp generators combining to a faster than light total effect. Another way to make the effect much stronger than in the ESA experiment is to conduct electricity through the supraconductors instead of relying on induction. Other, purely conjectural, possibilities include cooling high temperature supraconductors with liquid helium to make the effect extra strong, for who knows if it is the niobium itself that is crucial, or just the low temperature? It is worth an experiment anyway. But even without the third possibility, the first two, more well-founded possibilities can make the gravity-manipulating effect strong enough for practical use in space travel, make cheap launches possible, eliminate the need to carry propellant, and possibly even make Alcubierre drives and wormholes realistic. All well within our lifetime!
