Thought this might be of interest to cavers. Gives "POI" a whole new meaning...

That's really cool, Lynn. It sure does give a whole new meaning to the term "pee bottle". ;D

I wounder if the amount of power output has to do with what you eat and drink?

[L Roebuck]

It seems like standard power output levels because the prototype battery produced about 1.5 volts and runs for about 90 minutes. It states other bodily fluids tears, salvia, blood, and semen would also activate the battery but also lunch-box fruit-juice would be sufficient to activate it as well. So it seems that what you eat or drink would have no effect on the power output.
