"If a concept can't stand on its own without a subsidy from someone elses pocket, it isn't worthy of consideration."

Absolutely! I was jokingly trying to make that point. I was saying, the only way I would consider one of these is if someone else paid for the electricity.

of course, If some solar solution can be worked out, or, if you live in Chicago, you can plug it into your windmill.

I've noticed a ridge covered with large commercial windmills on a ridge southeast of Idaho Falls on some recent visits. Idaho is reliably windy. The solar approach really wouldn't be all that great at my latitude (averaged over the year).
