Generating the power is one thing. Getting that power to the consumer is a different kettle of eels (electric of course). Those big asses power lines didn't put themselves up or maintain themselves. The grid's owners are going to want enough of a cut of the sales to probably make the project unprofitable, for the near future. I'm not telling Apple anything they don't already know but remember Enron. This was their business plan.

Private space programs are fine and dandy, but who did all the research and design that made those free enterprise spacecraft possible? I believe a lot of the X Prize entrants relied on surplus military hardware to get off the ground. Go to the stars, businessmen, but don't forget who paid the upfront costs and buys your product. Ingrates.
