In the sci-fi novel 'Friday', Robert Heinlein writes about a physicist named Daniel Shipstone who realised that 'the problem was not a shortage of energy but lay in the transporting of energy. Energy is everywhere—in sunlight, in wind, in mountain streams, in temperature gradients of all sorts wherever found, in coal, in fossil oil, in radioactive ores, in green growing things. Especially in ocean depths and in outer space energy is free for the taking in amounts lavish beyond all human comprehension.'
In the story, Shipstone quits his job, retreats to his basement and invents a technology that packs 'more kilowatt-hours into a smaller space and a smaller mass than any other engineer had ever dreamed of. To call it an "improved storage battery" (as some early accounts did) is like calling an H-bomb an "improved firecracker."'
Like Ward and Musk [1], Shipstone eschews patenting his new technology in order to deny others the opportunity to steal it (or tie him up in court cases) and instead begins manufacturing the devices (eponymously named "Shipstones") which end up becoming ubiquitous, powering everything from flashlights and automobiles, to households and ocean-going ships. The company he founds becomes the largest and most powerful industrial conglomerate in the galaxy and the method of manufacturing Shipstones remains a closely-held secret.
