Joule Thief for the advanced student who
demands the most from the least.

Wow!  Thanks, that is a great resource of a lot of experimentation.

Interesting that boiling the potato helps the power output.  Excellent research.  I saw no mention of any JT circuit so, if they make enough juice to light that one led, then the addition of a JT circuit could enable them to light hundreds from the same power input.  Maybe they will figure this out?

Thanks,

Bill

These guys may be at a university, but they don't know science. The energy comes from the copper and zinc, not from the potato. The potato could be replaced with salt water. It is the copper and zinc that need to be replaced, so having cheap potatoes does not make for a cheap battery.

Now if they could make a battery without the metal electrodes... :)
