The Replacement For the Battery?
jackd writes "Great article in Technology Review, bordering on 'too good to be true,' about a small company in Texas that is developing the replacement for the electrochemical battery. The device is a kind of hybrid battery-ultracapacitor based on barium-titanate powders. Quoting: 'The company boldly claims that its system... will dramatically outperform the best lithium-ion batteries on the market in terms of energy density, price, charge time, and safety... The implications are enormous and, for many, unbelievable. Such a breakthrough has the potential to radically transform a transportation sector already flirting with an electric renaissance.'"
Everybody who can pump 90kW into a car battery, please stand up.
10 amp-hour 12V Li-Ion Battery: 500 grams ($100).
versus
10 amp-hour 12V Ultracapacitor (or 36-amp-second 12kV ultracapacitor): 50 grams ($100).
Current-limiting resistor of sufficient wattage rating to ensure that ultracapacitor storing that much energy won't vaporize any conductor that it happens to touch...: 450g. ($Priceless)
I find this shocking.
>> ultracapacitors.. we had supercapacitors till now..
>> whats next.. ubercapacitors? ubersuperultracapacitors..
googlecapacitors!
The good news: everything in the article is true, and they've already started production with a major worldwide OEM.
The bad news: it's Sony.

If you are ready to buy stock in this company after reading this article. I own a business that you might want to buy stock in. My company makes food replicators, the kind on star trek. We don't have a working model yet but it should be out in a year or two. Please send checks to.... you will receive your stock certificates in 6-8 weeks.
I for one welcome our new googlecapacitor overlords.
What was once true, is no longer so
I'm pretty sure the GP was referencing the practical joke of throwing a charged capacitor at someone. Obviously if that's funny on its own, then using a supercapacitor will be hilarious.

filling a gas tank and charging a battery are surprisingly different propositions.
So are filling a tank with gas compared with getting a bag of feed for the horse.
Sometimes it's best to just let stupid people be stupid.
It sounds as if you gobble a lot of kok.
Becuause the State of the Union speech is tonight?
Ok, this will sound like conspiracy theory stuff, but is it not interesting that a small company in *Texas* just happens to announce a 10- to 20-fold imrovement on battery technology - and emphasises cars more than they ought to - just when an embattled prez is preparing to announce new domestic energy policies, and is widely blamed for foreign policies that are driving up oil prices?
I was pretty sure the order was supposed to go:
Capacitor
SuperCapacitor
Capacitor64
Capacitor^3

Rubbish. Every year or so, some inventor comes up with an engine that runs on water, and it turns out to make about as much sense as the free energy machines of the 30s.
And every hour or so, a Slashdot poster fails to recognize the most blatant sarcasm.
Jeez Louise.

It does indeed sound aw.. ahh crap!! low battery warning!!

whats next..
FLUX capacitors.
