V kratkem naj bi v nekatere električne avte začeli vgrajevati nove "baterije" firme EEStor. Navednice so zato, ker to niso baterije s kemijskim načinom delovanja/shranjevanja elektrike. Iz za zdaj še skopih informacij se da razbrati, da naj bi bil princip delovanja podoben principu kondenzatorjev. "Baterije" naj bi imele več kot dovolj veliko avtonomijo in moč (800 km za 9 $ - po am. cenah el. energ., 300+ KM + XX navora), napolnile naj bi se v 5 (!) minutah, bile bi tudi brez nevarnih in škodljivih spojin.
Če je vse to res, v kratkem sledi revolucija v avtomobilizmu. Glede na to, da CNN piše o tej iznajdbi in jo uvršča med 11 najbolj vplivnih, je verjetno celo res. Let's wait and hope...

The Disrupted: Oil companies and carmakers that don't climb aboard
Forget hybrids and hydrogen-powered vehicles. EEStor, a stealth company in Cedar Park, Texas, is working on an "energy storage" device that could finally give the internal combustion engine a run for its money -- and begin saving us from our oil addiction. "To call it a battery discredits it," says Ian Clifford, the CEO of Toronto-based electric car company Feel Good Cars, which plans to incorporate EEStor's technology in vehicles by 2008.
EEStor's device is not technically a battery because no chemicals are involved. In fact, it contains no hazardous materials whatsoever. Yet it acts like a battery in that it stores electricity. If it works as it's supposed to, it will charge up in five minutes and provide enough energy to drive 500 miles on about $9 worth of electricity. At today's gas prices, covering that distance can cost $60 or more; the EEStor device would power a car for the equivalent of about 45 cents a gallon.
And we mean power a car. "A four-passenger sedan will drive like a Ferrari," Clifford predicts. In contrast, his first electric car, the Zenn, which debuted in August and is powered by a more conventional battery, can't go much faster than a moped and takes hours to charge.
The cost of the engine itself depends on how much energy it can store; an EEStor-powered engine with a range roughly equivalent to that of a gasoline-powered car would cost about $5,200. That's a slight premium over the cost of the gas engine and the other parts the device would replace -- the gas tank, exhaust system, and drivetrain. But getting rid of the need to buy gas should more than make up for the extra cost of an EEStor-powered car.
EEStor is tight-lipped about its device and how it manages to pack such a punch. According to a patent issued in April, the device is made of a ceramic powder coated with aluminum oxide and glass. A bank of these ceramic batteries could be used at "electrical energy stations" where people on the road could charge up.
EEStor is backed by VC firm Kleiner Perkins Caufield & Byers, and the company's founders are engineers Richard Weir and Carl Nelson. CEO Weir, a former IBM-er, won't comment, but his son, Tom, an EEStor VP, acknowledges, "That is pretty much why we are here today, to compete with the internal combustion engine." He also hints that his engine technology is not just for the small passenger vehicles that Clifford is aiming at, but could easily replace the 300-horsepower brutes in today's SUVs. That would make it appealing to automakers like GM (Charts) and Ford (Charts), who are seeing sales of their gas-guzzling SUVs and pickup trucks begin to tank because of exorbitant fuel prices.

The company, sources say, is weeks away from seeking independent verification of the product's performance, which will be conducted by the University of Texas at Austin or a U.S. army facility. If all goes well, EEStor could be in preproduction this year and full production in 2007. During this time, potential customers — from automakers and military contractors to tool and electronics makers — will get a closer look at the product.

Will EEStor Ultracapacitors explode?
EEStor claims to have invented a super-cheap, super-light, super-small replacement for batteries that could easily power electric cars for hundreds of miles. If true, they may make gasoline powered cars a thing of the past.
Simple math tells me that driving an EEStor powered car will be like driving with 100 pounds of dynamite in my trunk...
After carefully reading the EEStor patent, I found they only claim that the materials in their ultracapacitor are not explosive. Nothing is said about a fully charged ultracapacitor. However, fully charged, their described unit holds 52 KW hours of energy. See:
EEStor patent
1 KW hour is about the energy stored in 2 pounds of dynamite. It's also about the energy stored in 2 typical car batteries. Car batteries don't explode when smashed because the energy is stored chemically, and needs some time to convert to electricity. Instead, after a bad auto accident, you get acid on the pavement.
Electrical energy stored in a capacitor can't spill out onto the pavement. At least in any capacitor I know of, it's converted almost instantly into heat when the capacitor gets smashed. If true of the EEStor unit, that sucker will completely destroy your car (and possibly others nearby) when it gets damaged. Is this one of the reasons EEStor is so secretive about their new technology?

enofaznega vtikača s kabli preseka 1,5mm^2 ? Tak da zaenkrat še tu vidim problem glede polnjenja visokih kapacitet v kratkem času.
