seriously now...thank you

PORTLAND, Ore. — Say goodbye to your phone battery and charger. A new structural material could transform a mobile device's entire case into a hybrid super-capacitor/battery, making traditional batteries obsolete.
Researchers from Vanderbilt University's Nanomaterials and Energy Devices Laboratory are now designing materials that combine the best aspects of super-capacitors and batteries into a single hybrid material suitable for making such device cases. While the material's energy density is currently less than that of a lithium-ion battery, it makes up for density by the much bigger volume of a case -- plus it eliminates the space needed for a battery.
"My group is now looking at developing hybrid capacitors -- batteries that behave like capacitors -- that can maintain ultra-long cycling lifetimes like supercaps but store and deliver almost as much energy as current lithium-ion batteries," professor Cary Pint told EE Times about his work with doctoral candidate Andrew Westover at Vanderbilt.
Pint has hopes that his hybrid super-capacitor material can be built into the structure of all types of construction projects -- from the siding and drywall of homes to the chassis of airplanes.
"One of the key motivating factors in pursuing this technology was to develop energy storage materials that could be integrated into homes, which would increase the economic value of solar cells that are placed on the roof and enable a distributed energy electric grid system," Pint told us.

I really don't want my walls to contain 100K joules of energy. What if there were a fire? That energy has to go somewhere. And forget hanging a picture on a nail.

You got 20 kids and no TV Reality show?.....................
Guy’s... Seriously... 20 somthing as in 20” years old! Jessh.
That was my first though as well. Ouch.
Add to that, the cost of having your walls/ceiling be this fancy new material. Think your house was expensive before? Just wait.
It’ll probably be a 99% subsidized “green energy” project before we’re done though, so we’re probably OK.
Cost of a replacement battery: $175. Apple times two on backend costs.
Lightning in a box. No thanks.
If and when it get to the market at a reasonable cost I well be interested.
But where are all these miracle batteries that we been hear about for the last years.

Hmm...no battery for the car, just the body? Interesting.

I have heard Tesla’s technology could produce electric devices that run on ambient electricity.
Maybe those who say that saw “The Prestige” too many times.
That was the best part of that show! Giant squid grabs the boat, it rolls, and the crew grabs office fire extinguishers and assaults the wall-o-lights that’s now spitting smoke like a Texas barbecue. I know I was disappointed when computers turned out to be so boring. Well, there is ebay.
This technology has the potential to partially replace Lithium as an energy storage medium.
Top 10 countries by lithium supply:
Portugal – 10,000 tonnes
Zimbabwe – 23,000 tonnes
Brazil – 64,000 tonnes
United States – 118,000 tonnes
Canada – 180,000 tonnes
Argentina – 850,000 tonnes
Australia – 970,000 tonnes
China – 3,500,000 tonnes
Bolivia – 5,400,000 tonnes (estimated)
Chili – 7,500,000 tonnes
Chili, Bolivia, and the US have the largest known reserves of Lithium.
I’ll bet the rare-earth materials of these exotic new batteries will be even rarer than Lithium and will come only from mines in China. Trade Name: Unobtainium
That’s not going to be a problem. All future pictures and art in one’s home will be holograms of der Leader and other progressive democratic leaders...
