Charge in 5 minutes, Drive 500 miles?

ctroutwi writes "In the wake of rising gasoline costs there have been plenty of alternatives seen on the horizon. Including Hybrids, Biofuels, fuel cells and battery powered all electric cars. CNN has recently posted a story about a company (EEStor) that plans on offering Ultra-Capacitor storage products. The claim being that you charge the ultra-capacitor in 5 minutes, with approximately 9$ (~$.45 a gallon) of electricity and then drive 500 miles."

Re:daddypants email link broken?

[JaJ_D]

Just to clarify.....

I emailed the on-duty editor (regarding this being a dupe), like any good little /. subscriber. Unfortunately my e-mail bounced pretty much immediately. Normally I would resist the temptation to join in the /. circle-jerk that is shouting "OMG DUPE DUPE DUPE!!" but I wanted someone (ScuttleMonkey, etc) to note that the 'daddypants' email link is bouncing.
( ERROR: Use of uninitialized value in concatenation (.) or string at... Line 126 ) ..ScuttleMonkey, if you want the full error, feel free to let me know where to e-mail it.

On a sidenote, what seems odd to me is that not only is this a dupe that is currently visible on the index [slashdot.org] of slashdot, but that the article summary is almost identical to the earlier submission, and is even from the same submitter. Insert Matrix deja-vu quote here.

Sorry couldn't resist

Batteries and such

[gx5000]

How long until they're bought out and run to ground ? Last time we had a chance at EV cars, GM bought controlling share of the batterie technology and used their Delco crap. The higher performance batteries never really made it in the cars, just a few got the first line issues. And when GM got out of the EV business, they sold that controlling share to Texaco/Mobile, or was it exxon ? They want us to go Hydrogen and Biodeiesel next. The Electric car won't see the light of day until the Big Oil Profiteers get UberUber Mega Rich... Sad that we let them supplant technology and lie to us... Watch the film "Who killed the Electric car"...and the rest.. Cheers

More details..

There are some good details on this technology on Energy blog

http://thefraserdomain.typepad.com/energy/2006/01/ eestor_ultracap.html

A breif run down:

• It is a parallel plate capacitor with barium titanate as the dielectric.
• It claims that it can make a battery at half the cost per kilowatt-hour and one-tenth the weight of lead-acid batteries.
• As of last year selling price would start at $3,200 and fall to $2,100 in high-volume production
• The product weighs 400 pounds and delivers 52 kilowatt-hours.
• The batteries fully charge in minutes as opposed to hours.
• The EEStor technology has been tested up to a million cycles with no material degradation compared to lead acid batteries that optimistically have 500 to 700 recharge cycles,
• Because it's a solid state battery rather than a chemical battery, such being the case for lithium ion technology, there would be no overheating and thus safety concerns with using it in a vehicle.
• With volume manufacturing it's expected to be cost-competitive with lead-acid technology.
• As of last year, EEStor planned to build its own assembly line to prove the battery can work and then license the technology to manufacturers for volume production
• EEStor's technology could be used in more than low-speed electric vehicles. The company envisions using it for full-speed pure electric vehicles, hybrid-electrics (including plug-ins), military applications, backup power and even large-scale utility storage for intermittent renewable power sources such as wind and solar.
• They have an exclusive agreement with Feel Good Cars, a Canadian manufacturer of the ZENN, a low speed electric car, to to purchase high-power-density ceramic ultra capacitors called Electrical Storage Units (ESU). FGC's exclusive worldwide right is for all personal transportation uses under 15 KW drive systems (equivalent to 100 peak horse power) and for vehicles with a curb weight of under 1200 kilograms not including batteries.
