THE FRUIT AND VEGETABLE BATTERY BOARD
_________________________________________________________________________________________


I WAS SEARCHING THE FARM FOR RECYCLABLE OBJECTS TO BUILD A BATTERY BOARD THAT WOULD BE POWERED BY FRUITS AND VEGETABLES. I MUST ADMIT IT WAS RATHER HARD TO PRY HOLLY'S CUTTING BOARD FROM HER AS I EXPLAINED HOW I ABSOLUTELY HAD TO DRILL SEVERAL HOLES IN IT. THE OLD SCHOOL SCIENCE PROJECT WAS ONCE AGAIN CREEPING OUT FROM THE BASEMENT. BY PLACING A ZINC AND COPPER NAIL INTO AN ORANGE OR OTHER FRUIT, YOU CAN TAKE VOLTAGE READINGS TO SEE HOW MUCH ACTUAL POWER IT CAN PRODUCE. YES, FRESH FRUITS AND VEGETABLES CAN CREATE POWER, NOT ONLY WHEN YOU EAT THEM, BUT TO POWER OUR EVERYDAY ELECTRONIC GADGETS. SO I FIGURED I COULD LINK THE VEGGIES TOGETHER WITH A BOARD APPROPRIATELY WIRED, TO OBTAIN HIGHER VOLTAGE. SOME FRUITS AND VEGETABLES HAVE PRODUCED AROUND 3 VOLTS FOR WELL PAST A MONTH.



ABOVE YOU CAN SEE I HAVE HAMMERED PAIRS OF COPPER AND ZINC NAILS IN THE BATTERY BOARD. FRUITS CONNECT THE TWO DIFFERENT NAILS MUCH LIKE A WIRE, AND COPPER WIRES UNDER THE BOARD CONNECT ONE SET OF NAILS WITH FRUIT TO THE OTHER. EACH FRUIT CAN PRODUCE APPROXIMATELY .20 VOLTS, OR 1/5th OF A VOLT. I HOOKED UP A 12 VOLT CONNECTOR THAT WILL ACCEPT A CELL PHONE CHARGER PLUG THAT YOU WOULD NORMALLY PUT IN YOUR CAR'S LIGHTER SOCKET. THERE IS ENOUGH SPACE ON THE BOARD TO HOLD 15 FRUITS, AND OR VEGETABLES. (potatoes last longer!)



IN THIS EXPERIMENT I USED SEVERAL DIFFERENT TYPES OF VEGETABLES AND FRUITS. EACH FRUIT SHOULD USUALLY GO ON ONLY ONE SET OF NAILS BEING, ONE COPPER, AND ONE ZINC. I ALSO WANTED TO SHOW HOW YOU CAN PUT LONG VEGGIES ON SEVERAL NAILS, AS THE CELERY IN THE PICTURE SHOWS (as long as you use two nails at a time). I TOOK AN OPEN VOLTAGE READING OF THE BOARD AND IT FLUCTUATED BETWEEN 10 AND 14 VOLTS. THE MULTI-METER I HOOKED UP TO THIS BOARD WAS READING BETWEEN 2.5 TO 3 VOLTS, WHILE THE FLASHING L.E.D. LIGHTS WERE PLUGGED IN. SO BASICALLY, THIS BOARD CAN ONLY PRODUCE UP TO 3 VOLTS FOR AS LONG AS THE FRUITS AND VEGETABLES LAST. HOWEVER, SEVERAL OF THESE BOARDS CAN BE LINKED TOGETHER TO CREATE MORE POWER IF NEEDED, AND IF YOU HAVE A FRUIT TREE THAT DROPS A LOT OF FRUITS, THIS IS A GREAT WAY TO RECYCLE THEM AND GET FREE ENERGY!

BELOW YOU CAN VIEW VIDEO SHOWING THE POWER
PRODUCED BY THE VEGETABLES IN THE PICTURES ABOVE.
