Can't wait to strap some of these to the side of my desktop or the bottom of my laptop and make use of that waste heat. I'm sure I can do something or other with the approximately 2 mW I'll generate.
2mW would require about 1.5m² of area. I could maybe see this being used to pull a little bit of energy out of a room to charge batteries or capacitors to run sensors or other low power devices in short bursts. But you could harvest more power just by turning a hand crank generator for a few minutes. An average solar panel is like 10k times more efficient. I could still see some sort of use for it, maybe for being embedded into floors and ceilings of buildings to passively run sensors. There would be a small cooling effect on a room with enough of it.
Oh, if only it were that powerful! Their best result produced 94 nanowatts per square centimeter, or 0.94 milliwatts per square meter.
2 mW would work better than Sony's generator in some cases.
