I was totally with him as to the power source thing, thinking "okay, wow, never knew that, interesting." And then he's suddenly BOILING the potatoes, which is gonna make them go bad WAY FASTER than if they're raw. And I dunno why he didn't leave the potatoes WHOLE, he never explained THAT (he DID get a reading from the whole potato). This guy was onto something interesting, but then his experiment took way too long because he had some pretty bad logic. The whole Raspberry Pi over to the Texas Instruments thing ... maybe he shoulda hooked up his potatoes to a pregnancy test.
