The most difficult aspect of hydrogen fusion is overcoming the electrostatic forces that cause the hydrogen nuclei to repel each other. Would it be possible to place one of the nuclei inside some conducting sphere like a Buckminsterfullerene so that the fullerene acts as a Faraday cage? The fullerene would have an induced negative charge on the inner surface, and an induced positive charge on the outer surface. When the second nucleus is brought nearby, the positive charge on the outer surface will accumulate on the side of the cage further away, and some negative charge would accumulate on the side closer to the outside positive charge. Would this setup effectively weaken the strength of the electric field that either one of the nuclei encounters?
