Potato-Powered Batteries Debut

kdawson posted more than 4 years ago | from the energizer-tuber dept.

Earth 284

MojoKid writes "Yissum Research Development Company Ltd., the technology transfer arm of the Hebrew University of Jerusalem, has just introduced what it's calling 'solid organic electric battery based upon treated potatoes.' In short, it's a potato-powered battery, and it's as real as you're hoping it is. The simple, sustainable, robust device can potentially provide an immediate inexpensive solution to electricity needs in parts of the world lacking electrical infrastructure. Researchers at the Hebrew University discovered that the enhanced salt bridge capability of treated potato tubers can generate electricity through means readily available in developing nations."

+1 Insightful. If I am a 3rd world citizen, lacking food or means to purchase it, and I have some potatoes, and I am hungry and I have a flashlight or radio or whatever that needs juice, well, they are going to remain without power as I gobble down. Now if it was something like a person with an iPad, even if they are starving and impoverished, I think they would choose differently due to reality distortion fields. How they got the iPad I don't know, that is an exercise for the reader, and that reality distortion field is strong enough these days that there should be some sort of energy harvester for it in the works anyways.

I'm currently seeking a grant to build a reactor based around Steve Jobs.

Harvesting the power of the distortion field is paramount to ending the world's oil addiction. Unfortunately, as he grows old we will find a new source to power the reactor. The boys in the lab have cooked up a cocktail of pheromones, viagra, ginseng and amphetamines to ensure we have a healthy stock of potential reactor rods.

bingo, I'm thinking of the farmers in remote villages in Africa that use cellphones to check market prices to determine when and where to bring their crops to market to optimize their income. Theoretically that's a win-win as well since the prices are higher because there is more demand for his foodstuffs than there is supply.

Yes, because they grow potatoes in the remote parts of Africa...I wish you were right afidel, but honestly most produce that "goes to market" comes from what one could dub superfarms it seems, at least those distribution companies that are publicly listed.

THANK YOU. That sort of mentality disgusts me. I stayed at a place in Belize near the Guatemalan border once, and that place is third world by anyone's definition. And walking down the streets you had to dodge the chickens and keep an eye out for falling mangoes. I'm sure that if they had a way to power their cell phone towers with mangoes and chickens (and other plentiful items, they'd be thrilled to do so.

Re:Puff piece (5, Informative)

LambdaWolf (1561517) | more than 4 years ago | (#32629656)

I believe the news here is that the technology is pragmatically usable (a potato battery used outside of an elementary school classroom? That's news) and in a way that's more economical than equivalent sources. From TFA:

Cost analyses showed that the treated potato battery generates energy, which is five to 50 folds cheaper than commercially available 1.5 Volt D cells and Energizer E91 cells, respectively. The clean light powered by this green battery is also at least 6 times more economical than kerosene lamps often used in the developing world.

Re:Puff piece (0)

Anonymous Coward | more than 4 years ago | (#32629750)

They're probably comparing the cost of the potatoes with the cost of regular batteries, thinking that the energy comes from the potatos. In reality the battery is metal-powered as it's the zinc and copper that provide power when they dissolve.

Re:Puff piece (1)

afidel (530433) | more than 4 years ago | (#32629810)

So? If the current solution has you purchase cathode, anode, and electrolyte and the new solution just anode and cathode it's probably going to be cheaper.

Re:Puff piece (1)

zill (1690130) | more than 4 years ago | (#32629882)

This cheap, easy to use green power source could substantially improve the quality of life of 1.6 billion people, comprising 32% of the developing non-OECD populations, currently lacking access to electrical infrastructure. Such a source can provide important needs, such as lighting, telecommunication, and information transfer.

But they're not marketing it as cheaper battery alternatives. They're proposing to use it to light light-bulbs and run computers. They're claiming this technology can compete with solar, wind, and geothermal power generation on the basis that it's "five to 50 folds cheaper than commercially available 1.5 Volt D cells and Energizer E91 cells, respectively".

Re:Puff piece (1)

sumdumass (711423) | more than 4 years ago | (#32629912)

Wouldn't solar, wind, or geothermal constitute an electrical infrastructure? I think the idea is to use these instead of batteries that are in use already because the solar wind or geothermal isn't set up yet. It doesn't seem like it's meant to replace existing infrastructure, just fill an expensive gap where funds may be tight.

Re:Puff piece (1)

billcopc (196330) | more than 4 years ago | (#32630076)

Sure it's cheaper, until they run out of zinc and copper and prices skyrocket.

Then they're fucked.

Re:Puff piece (1)

sumdumass (711423) | more than 4 years ago | (#32629888)

Actually, I think the simple process that "nets/gets" more energy is the news. It seems that if you boil the potato before making the fifth grade science experiment, it alters some salt bridge inside the potato getting a 10 fold energy output potential. Now boiling potatoes probably isn't the really insightful portion, it's that this same salt bridge area is supposedly hampering more efficient battery development so the process changes could also lead to other developments.

Of course the article doesn't go into what the salt bridge is and being a typical /.er, I am commenting without looking it up first so I could sound as clueless as I really am here.

The scientists discovered that the simple action of boiling the potato prior to use in electrolysis, increases electric power up to 10 fold over the untreated potato and enables the battery to work for days and even weeks.

Thanks, that made me chortle :) At first I agreed completely - it seems silly to waste energy boiling potatoes just to increase battery efficiency. Now that I think about it, though, you could boil them easily enough using a solar-cooker type device. I'm not sure what the availability of those is in the third-world, though. If they're not in wide use, I'd say teaching people how to make them would be a lot more useful than showing them how to make potato batteries.

A fire is easy to come by. And chances are they already do some regular cooking, so adding potatoes is no big deal.

Re:Puff piece (1)

mysidia (191772) | more than 4 years ago | (#32630196)

I would assume they do normal cooking, but to boil potatos in sufficient quantities to actually have a useful source of electrical power, will require more fuel to burn for their fire.

Otherwise, they might as well stick with sediment batteries...

Re:Israel and batteries (4, Insightful)

ChromeAeonium (1026952) | more than 4 years ago | (#32629902)

Possibly because solar power is pretty big in Israel, so high tech batteries are in their best interest. And, just some baseless postulating here, but when you're surrounded by neighbors who don't much care for you whose biggest asset is oil, improving those alternative energy techniques might be a good idea. If Israel perfected solar power & storage, that could conceivably go a ways towards helping the world kick it's oil habit (solar powered batteries for your house and car), which would cut into the cashflow of said neighbors. So, batteries are good for them, and there is a chance that maybe possibly we're seeing some sort of scientific-economic-political strategy at work here.

What you say would be true only if potato production were limited to current levels and if there were no surplus. In fact, potato production could be increased to accommodate use for batteries, and in any case th ere is actually a surplus. Total world food production is adequate - the reason that some people starve is poor distribution of the available food, in considerable part due to political reasons. (Starvation in North Korea, for example, is the result of the incompetence of the country's government.)

Re:Really? (2, Informative)

sumdumass (711423) | more than 4 years ago | (#32629980)

You didn't either.

What they did was manipulate the salt bridge in the potato in a way that increased the output by ten fold. They found this was as simple to do as boiling the potato. Basically, they took something already known, and known to be limited, and raised those limits until it became somewhat practical for use in some situations.

In case you do not know what a salt bridge is, it's a conduit that allows ions to pass from one side of the battery's reaction to the other so the electrons do not create an imbalance and halt the flow when it gets saturated. In a traditional potato, this is limited, in a boiled potato, it is ten times (or up to) more efficient/effective as the article claims.

If you want energy, you could ferment them tatties, distill good 'ol CH3CH2OH and burn it. You might get more watt-hours/spud this way and there'd be no electrodes to replace.

Now, if you actually need small, cheaply refillable batteries for portable devices, this would be nice provided the electrodes don't wear out too much.

How smart: Destroy a food source ..... (0)

.... to give electricity to the poor and hungry.

Renewable my azz. All this will do is destroy another food source to generate energy. So destroy the environment with "modified potatoes" and contaminating the few fertile land remaining.

Guess what ethanol did to the prices of food??? And did it lowered the cost of fuel??? The scam made more money for the oil companies. Add 10% ethanol to regular fuel, and you loose 20% millage per tank. That was a 20% benefit and the fuel is still costing the same as if it was 100% petro.

Didn't anyone else leave their potato clock sitting around running for way too long as a kid?

The potato rots. It turns into a pile of mush. They even addressed this in Dexter's Lab. How exactly have they circumvented that problem by just boiling the things? I don't see anything about that in the story.
