If many of the existing fixtures in a particular home or institution still happen to require the use of fluorescent light bars, the significant energy loss that escapes as heat waste could at least be put to good use. This would be possible through the installation of the Heat-Electricity Conversion Storage Device. It's a concept now, but what a brilliant product it would be!
The snap-on contraption would be easily fixed to the light source so that it can begin absorbing the heat lost and transfer it to useable electricity with thermoelectric conversion material. This energy is stored in the other half of Xiaoping Chen and Shuguang Li's gadget, which supplies a USB port for charging your smartphones, cameras and tablets in an eco-friendly way.
