Potato-Powered MP3 Player (Video)

Totally bogus. How do the electrons get across the air gap between the potatoes? Maybe he thought we wouldn't notice or maybe he is so clueless that he doesn't realize the gross error in his little illusion. Also, though dissimilar metals are mentioned, it certainly appears that the nails stuck in the potatoes are both just common nails.

I agree with rcapper, this is total and complete garbage. I tried to expand the image to check if there was power supplied down the speaker cable but the image quality is too poor.

He may have two dissimilar metals but they aren't in an electrolyte as well as, as rcapper pointed out, no path for electrons to flow between the potatoes. He may be fooling himself and his MP3 player has a super cap in it that keeps the power up for some time when the batteries are removed. If that isn't the case then I would suggest that there are some hidden cables somewhere that are supplying the power.

In any case it's a total load of bovine excrement and this is probably the worst place on the internet to try and pull off a scam like this.

To further beat a dead horse, I am not aware that sweet potatoes contain any appreciable phosphoric acid (could be wrong here).

Also, would 1 volt at .4 milliamps be enough to power the MP3 player? The 2 batteries he removed equal 3 volts.

Tad

Even if it did, I seriously doubt the potatoes have that kind of power to drive those speakers. The speakers are huge!
