Much has been made about "peak oil", which is the moment when the production of crude oil stops increasing and starts its inevitable decline. Most people don't concern themselves with this event, but those of us who do often speculate on what the future holds in terms of energy production.

Remember those novelty solar cigarette lighters? Well, I'm thinking this article shows us which direction solar energy is really headed.
