WhoTom Posted January 29, 2020 Share Posted January 29, 2020 LEDs don't use much power, and when you consider the energy required to boil the potato, it's a pretty inefficient way to power a light. 1 1 Link to comment Share on other sites More sharing options...

Can the user be able to boil their own potato battery? Spread that inefficiency around??? Link to comment Share on other sites More sharing options...

I dunno....apparently it's the cooking, not the boiling per se and it's just a slice of potato....you can steam 4 potatoes in 10 minutes in a medium pot, so presumably you could either light the entire house for a month or just cook dinner and take out a slice. Sounds efficient enough to me! Link to comment Share on other sites More sharing options...

apuszczalowski Posted February 3, 2020 Share Posted February 3, 2020 Who wouldn't want a bunch of rotting potato's sitting around their house with wires and LEDs attached to them to save a few bucks lighting their house. But what if there another potato famine? Link to comment Share on other sites More sharing options...
Saxum Posted February 3, 2020 Share Posted February 3, 2020 Quote The potato battery kit, which includes two metal electrodes and alligator clips, is easy to assemble and, some parts, such as the zinc cathode, can be inexpensively replaced This is probably part of limiting factor plus factor that outside lab controls will not be as precise, electrodes not cleaned, etc. which affect power output. We did this kind experiment in high school in 70's. The energy to boil the potato is not issue. The places this device is intended on going to can burn dung as fuel to cook a potato.

Gotta be better than those do nothing wind turbines. Did the NY Thruway ever get their turbines running? Link to comment Share on other sites More sharing options...

Did the NY Thruway ever get their turbines running? I used to always wonder driving by farms why I never saw the small wind turbines in the fields spinning in them, even when it was windy. Then just recently I found out they aren't wind turbines but fans that are used to circulate and move warm air around and prevent frost from damaging the crops.......
