Lemon battery...

One of my wildest dreams was to build lemon or potato battery to power Raspberry Pi...

I always thought that it should be easy.

~14 years ago on some industrial fair one of companies was showing some small device powered by potato battery, so I thought that this should work with Rasbperry Pi too.

Problem is that according to science (or at least Wikipedia ;-)) lemon battery build from 1 lemon gives up to 1 mA of current...
And according to this site minimal current needed for RPi vary from 80 mA up to 1250 mA...

So it seems that I would need at least 80 lemons only to power RPi....

It doesn't look as viable plan ;-)

And it also seems that this company I remember wasn't showing working device ;-)
They would much more energy to power device, especially that this was some device connected to GSM modem ;-)
