I just did the calculations, and apparently it's spent about 20,000 VA so far, at 1 nanoamp per ring, 10 billion rings, and 2000 volts.<br><br>Once it stops, it'd be beneficial for humanity to figure out what it's made of. That power density is amazing.,(reply>), Leo Curious Wow, that is about the size of a typical cell phone battery, coincidentatlly.<br><br>Til this point, I did not know if this battery was being recharged (false) or if it was running on the original charge like a disposable battery (true).,(reply>), Well you did the calculation wrong then.<br>1nA = 0.000000001A<br>2000V<br>176 years are ~ 1.5 million h<br>Now multiply current by voltage to get the VA / watt = 2µW<br>Now multiply by the time to give the energy of 3Wh.<br>Current 16850 Li-Ion batterys hold about 10Wh in a much smaller package.
