Modified Mobile Phone Runs on Coca-Cola

Daizi Zheng, a Chinese developer who is currently based in London, has modified a Nokia cell phone to run on Coca-Cola or any other sugary solution.

Zheng says the modified phone can run three or four times longer on a single charge than a phone using a conventional , and can also be fully biodegradable.

As Zheng explains, a sugar-powered phone could potentially offer a much more environmentally friendly power source than lithium ion batteries. The new phone's bio battery, which basically acts as a , uses enzymes as the to generate from carbohydrates.

The phone can run for several hours, and produces water and carbon dioxide as the battery runs down. The phone can then be emptied out and refilled with more Coca-Cola.

Zheng designed the phone as a client project for Nokia, but there's no word on whether the company plans to incorporate the concept into future products.

"It brings a whole new perception to batteries and afternoon tea," Zheng wrote on her project's website.

Trouble is, sugar comes from plants, which are normally used for food. So we're back to the whole biofuel idea.

Might as well skip a few steps and the inefficiencies involved with sugar synthesis/harvesting, and just use a DMFC -- such as ones being developed by MTI Micro...

Still doesn't solve the problem of energy for devices competing with the basic human need to EAT. Hm, shall we power our gadgets, or fill our stomachs? Hard decision, there...

It also produces lethal Carbon Dioxide!

That's right we all eat coca cola so we should worry about a coke shortage in the future. I'll stop cleaning my battery post too just to make sure we can feed the world! Getting serious.... coke is bad for you, period. So this could be the best use for the main reason america is FAT. Coke shares should skyrocket!

Best use for coke! Otto, WTF man! the point is that CURRENTLY ALL BATTERIES ARE SHITTY! Also this is a great idea. Just like the crank flashlights. You can crank or you can use the internal battery

some more technical detail is needed, which enzymes are used to prmote the reaction?, what's the name of the techniques used and principles involved?

Could be very useful in developing regions where batteries are too expensive / hard to come by (and where there is no infrastructure for recycling)

Some independent confirmation please?

This is just a concept, not a real product. This person is a designer, not a scientist or engineer, s sorry, if I'm not buying this.

I was expecting them to say they were using the acid for energy... if they ignore the acid inherent in Coke in favor of using just the sugar, seems like a waste of a lot of energy. Seems like a fun, gimmicky device, though I won't buy one if it doesn't run on beer

The only problem I see with wonderful technologies like this is that so often they get written up, but never show up in the marketplace. I hope this one makes it -- despite "sugar is food" and "lethal CO2".

It's a neat technology and a good idea, but it's not going to solve the energy problem. "coke shortage" isn't the problem with biofuel sources and ideas like this. Biofuel investment leads to higher basic foods prices, like corn, which leads to fewer people being able to afford the food coke is derived from, not the coca cola.

The other problem is that large scale use of a technology like this would necessarily couple biofuel to cell phones. The nice thing with batteries in the phone is you can use any source of energy to charge it, so in nevada, maybe solar power would be the best, while in places with excess rain, hydro would be the best, etc. Investing in better, green energy storage technology might be a better idea for reducing the environmental impact of cell phone batteries.

it's a great idea, nothing wrong with it & in an
event of calamity where there is a break down in
human services it could help people survive longer
in emergencies, as long as the main system running
the phones are now also knocked out. so bring it on
I love the idea, but I predict we my never see it happen because of GREED of the battery companies,
so will we get it, we will just have to wait.
