As has been mentioned in other threads-
A flywheel based power supply would be nice. As would a large vacuum chamber, some surplus MRI superconducting magnets, perhaps a super computer, or clever host (and programers)for a distributed computing enviornment. All sorts of diagnostic equipment, some skilled transformer/ magnet wire wrappers, machinists, engeeners, well managed and disiplined think tanks (avoid NASA type -one step forward, ten steps backwards type programs), computer illistraters, spin docters, managers with checkbooks for farming out various sub projects and confirming/ confidence building/evangelical studies. And of course several individuals like myself who would be very well paid for very little competence.
