Cheap, High-Performance Green Battery Runs On Rotten Apples (gizmag.com)
Zothecula writes: Researchers at the Karlsruhe Institute of Technology (KIT) have repurposed discarded apples to build cheap and high-performance sodium-ion batteries, making a green technology even greener. The advance could find use in grid storage and, after further development, compete with lithium-ion cells to power portable electronics and low-end electric cars.
How would this compare to using discarded oranges.
Those that refuse to be decrypted?
After all, it's not like electricity is a commodity that we can send anywhere - just as the water knows it's going to a sink rather than a toilet, the electricity from rotten apples won't go to high end cars.

Until the sun comes up.
And then just enough for the heat pump all night will do.
How do you like them apples, huh??
Real Life Mr Fusion?
Sorry, but I have to go here: http://i192.photobucket.com/al...
Finally?! ^_^
Many people were on the ethanol bandwagon due to the notion that alcohol could be made and less oil used for fueling cars and machinery. But there was a huge issue not considered. Farmers raising crops to create ethanol caused the price of food to severely increase. After all the land once farmed for food was suddenly farmed for fuel. So the next idea was to use more land to make crops. That also penalized all of us. Less natural land meant more pollution, with bad effects on nature and human health and also involved the use of water which in some areas is in critical shortages. Now suppose we simply use all the apples that don't look nice or have bad spots on them to help make electricity. You can bet that all those apples have been used to feed hogs and other livestock as well. Even orange peels are used to feed cattle. The world is in a terrible bind and the crucial fact beneath it all is that we very much need to reduce the reproductive levels of the population. No matter how far we push science and technology we still have an urgent need to limit births are we simply will all perish. As I type this, billions of gallons of fresh water, contaminated from sugar cane farming is being dumped into Florida's India River Lagoon, which is a salt water lagoon. The effect is so radical that we can not touch the water without risk of disease and the wildlife is being murdered in this huge lagoon. The reason the water is being dumped has to do with the farms being flooded with fresh water and the risk of the dyke around Lake Okeechobee collapsing and killing thousands of people. Yet there is very little choice but to farm that land due to our nation's need for food.
Android has had this feature from day one. Glad to see Apple is finally catching up.
The article (I know, for some reason I actually read it) mentions hard carbon. Isn't that diamond?
...to see German engineering innovation squandered on pointless, feel good green malinvestiments like this.
Something useful you can do with a Mac.
20% of the cost of Lithium ion per unit capacity is still not cheap compared to the cost of electricity from the grid. For widespread home storage you need to bring costs down to less than 5 cents per kW/hr, (1/2 grid costs ... significantly less than grid to combine with rooftop solar) and grid you likely need less than 2 cents per kWhr. (1/10-1/4 retail,) (the difference between the spot costs from base-load or fuel-less sources of (nuclear coal, wind, solar) and that of oil/fast-start natural gas)
So when can I charge my cellphone and get a shot of penicillin?
Wake me when you can run a toaster with it.
It seems that every week we some "green power" technology that produces 0.3 yoctowatts of power, involves the slight jostling of 3 electrons, and claims industrial level of application.
I call bullshit. Stop stealing ideas from the local school science fair and develop something that will power something useful, and demonstrate it.
Left MS Windows for Linux Mint and never looked back!
Vote for Bernie in 2016!
So this only works with green apples?!?
What about rotten MacIntosh apples. There should be loads of those around.
Rotten Apples?
So, the DOJ won.
Table-ized A.I.
I can not take anything coming out of that university seriously since they renamed themselves to Karlsruhe Institute of Technology (KIT) to leech off the Massachusetts Institute of Technology (MIT) brand. Their Wikipedia entry reads like a brochure, too. Goddamn posers.
Just sayin'.
Most of the apple batteries discarded have perfectly functional cells. The connections between them corrode quickly because they started using politically correct solder instead of lead, sending millions of perfectly good batteries to the dump
Is the sodium-ion battery with rotten apples any better than extracting the alcohol (ethanol, specifically) and burning it for fuel? I thought the best use of sugary crops (sugarcane or corn seem to be ethanol favorites) was to create ethanol?
I thought you were supposed to use a potato :O
It was predicted by Dr Emitt Brown that by 2014 we will be producing energy from food scraps, 88 Gigawatts to refuel the flux capacitor. No need to steal plutonium from Libyan terrorists.
sed -e 's/Chuck Norris/Rajnikant/g' joke > fact
One bad apple increases the electricity generating capabilities of the whole bunch.
Don't waste your vote! Vote for whoever you want, unless you live in a swing state it won't matter anyways
I've always been under the impression that once a Mac or another Apple product died, you replaced it. Now I know that they are still useful.
I suppose it's a good thing for KIT that the courts are requiring Apple to decrypt their devices.
They want to use this technology to turn rotten apples into carbon anodes for electric batteries? I have what I believe to be a better idea. A process that uses consumable carbon anodes is aluminum refining. Right now they are made from coal, but if made from fruit this closes the carbon cycle on that process and we won't be digging up carbon any more to just dump it in the air.
There are some crazy people out there that think we shouldn't be using aluminum anyway, but also use wind and solar power. What nut jobs, what do they think that solar panels and windmills are made from? Apples?
Use the rotten apples to make aluminum. Keep digging up aluminum for windmills and wires. The stuff left over from the aluminum mining can be mined further for uranium and thorium. Put the uranium, thorium, and spent nuclear fuel from all those old nuclear reactors into a waste annihilating molten salt reactors. Those molten salt reactors will destroy the old waste, produce energy, and give us vital radio isotopes for medicine and industry. The energy from the reactors can be used to make more windmills, synthetic fuels, and leave the ethanol for making wine, whiskey, and beer.
I am armed because I am free. I am free because I am armed.
Police stations could be self-powered.
I think I might rather have my batteries catch fire.
I'd think running on sour grapes would drastically increase supplies and yield more potent batteries.
