A man with the genius of a great scientist, who chose to be a commercial inventor? I find it outrageous. He wanted a motor, and he quietly performed a major revolution in the science of energy, just as a means to an end, and he didn’t bother to publish his findings, but went right on making his motor. Why did he want to waste his mind on practical appliances?” “Perhaps because he liked living on this earth,” she said involuntarily.
