Okay, we’ve been getting some strange sources of power lately including the lemon power and candle power, here’s potato powered MP3 Player!
We are working on our touchscreen MP3 player by the way, we are trying to locate a
CSS CCS PIC compiler this week so hopefully by next week we will have it made.
This appliance is, of course, closely related to the lemon battery (or more formally lemon cell) familiar to anyone who’s searched for a high school science project. Two different metallic objects dipped into a conduction solution (an electrolyte) will produce an electrochemical reaction the byproduct of which is electricity. A single lemon is usually enough to illuminate a flashlight bulb, but two sweet potatoes are apparently required for an mp3 player. Yes, it reduces the portability of your player, but just think…no more buying batteries! Of course, things might get a bit smelly as those sweet potatoes (Ipomoea batatas) start to go off.
