Need Light? Boiled Potatoes Can Supply Enough Power To Light A Room For 40 Days

Woah – now this is some cool science!

If you ever find yourself without power (ya know, like poor Texans did last month) you might be wondering what you can do for light aside from traditional battery operated flashlights and lanterns.

Well, this might just be the coolest way to light up the dark… boiled potatoes!

Yes, I said potatoes as-in the food everyone loves!

Potatoes are used for so many delicious foods such as mashed potatoes, fries, tater tots and the list goes on.

But aside from being delicious, potatoes can actually be used as an energy source much like a battery.

Cool, right?

A professor named Haim Rabinowitch at the Hebrew University Of Jerusalem found that by putting two metal rods into a potato, it created a chemical reaction allowing it to supply power.

What’s even cooler, they found that if you boiled the potatoes for 8 minutes, it gave a ton more energy.

In fact, boiled potatoes are about 6 times more inexpensive than a regular 1.5 v AA battery.

And a boiled potato can provide enough power to light a room for up to 40 hours! Isn’t that amazing?

So, sounds like we all need to learn how to create potato batteries in case we are even in a bind and need some electricity! I say, keep these items handy in your emergency kit at all times!

You can see how these Potato Batteries are made below.

I really can not believe that some of the people commenting are adults? it’s like reading comments from middle school students or watching a presidential debate?

Did you NOT see Professor Proton on TBBT? HE told how to make a potato CLOCK.

Hi everyone out there.... I cooked my potato in the microwave. And guess what... the lightbulbs didn’t work... CLF or LED... was that because of the microwave.

Wow. How useless is this to the people in Texas that don't have power in the first place. Ll

@Anthony, that's why you build a fire I know you're not that dumb

@Anthony, haven't you ever gone camping and cooked stuff over the fire? People lived for tens of thousands of years without electricity. If you don't have a fireplace, build a fire in the back yard and once you get a good bed of coals going, you can cook a whole lot of different ways. On a spit to roast, on a metal you can cook by frying and boiling while you can bake by wrapping in foil and bury it in the coals. The people without power can still cook if they are willing and have at least half a brain

@Kj, tell him wow think man. Think.

@Anthony, they could start a fire as if they were camping. Sometimes we need to think outside the box.?

@Anthony, if you are prepared you have alternative cooking sources. Sterno, charcoal, wood and camp stoves. You can use them to heat up bricks to help with warmth and to cook and boil water for clean water. And now light.
