Tealights can be used to create a mood in a room and for emergency lighting when the power inevitably goes out in the windstorm, but never had I considered using them to generate power. The latest in a long line of Kickstarter successes (or about-to-be successes), the tPOD1 (yes, they went there) can generate a small amount of power – suitable for a USB light, for example – for quite a while. Off the heat of one tealight. There’s a video through the link, well worth a watch.
