Carbon nano tubes may make a good platform for launching EVs. An EV accelerated by a chemical differential voltage of up to 3 volts could accelerate a deuteron up to an energy of 3 * 2 * 1836 = 11 keV. Enough to bring about a fusion reaction. Regards, Robin van Spaandonk http://users.bigpond.net.au/rvanspaa/ Competition provides the motivation, Cooperation provides the means.
