A hundred and fifty years before, when the parochial disagreements between Earth and Mars had been on the verge of war, the Belt had been a far horizon of tremendous mineral wealth beyond viable economic reach, and the outer planets had been beyond even the most unrealistic corporate dream. Then Solomon Epstein had built his little modified fusion drive, popped it on the back of his three-man yacht, and turned it on. With a good scope, you could still see his ship going at a marginal percentage of the speed of light, heading out into the big empty. The best, longest funeral in the history of mankind. Fortunately, he'd left the plans on his home computer. The Epstein Drive hadn't given humanity the stars, but it had delivered the planets.
