I just wish I could get my hands on a few .

Aren't those the Ultra Capacitors that EESTOR has been working on for a few years now? They are working on those Capacitors for a company named ZENN Motors who make electric cars up here in Canada. (but they can't sell them in Canada Stupid Government). Judging by an article I read about the new crop of ZENN cars for 2010, I think they might have achieved their goal.

Here's a quote from the ZENN Motors website.
''The ZENNergy™ drivetrain solution promises to deliver energy storage packs that are
• one-tenth the weight and mass of lead acid batteries,
• capable of one million-plus cycles,
• able to be fully recharged faster than any electrochemical
*battery and deliver superior performance in extreme
*operating temperatures
• safe
• cost effective – lower cost than current Lithium Ion
*battery technology''

No, they are actual batteries being used by various military clients. I really don't know how ZENN will actually produce those as it seems a bit of science fiction to be honest. If they have such technology, it'll be worth a huge amount of money. It seems more like a scheme to get dumb investors to throw more money at them. Look at the companies getting grants from the US Government to make electric and/or hybrid vehicles. If it's actually a capacitor, it will be like any other capacitor we currently know of. I know of a company in Canada that actually has a few working capacitors and some have been used in 1:1 racing application. I plan to use those in my 1:1 race car as well. I can come up with juicy ideas as well and throw it in a website to milk investors for money, but why should I do that. The people I've currently spoken with about my 1:1 race car don't actually think its doable, but I know it is as the technology is already available now. I really should make some BS story, they'll probably fall for that.

Choose not to believe in it, that is your prerogative. The science fiction in question is called EESU from EEStore, which centers around a core of aluminum coated barium titanate powder immersed in a polyethylene terephthalate plastic matrix. They filed for a bunch of patents that have recently been granted regarding this new technology.

I think the British Columbia government has or will change the automobile act/regulations so cars like the zenn Could be driven on the Street of B.C..

Hmm, 3000 cycles and still holding 80% capacity. That would make a great 1:1 car battery for an all electric. 8 years of lifespan... If we were making electricity with nuclear (or fisson) it would be the way to go. Coal fired power is not really optimum for electric cars...

They are being used in Tanks, Fighter jets, Directed energy weapons, Electromagnetic launchers, Light sabers and so forth. I'm trying to get a few to test it for my 1:1 race car and also to see if it'll handle my 1.5T motor .

Yeah, that's what I thought too. But don't forget about the variables found if you take the resistance of the base ohmage and multiply by the sum of your top speed and heat index, you can then decide to what degree you need to set the hyper-threading mechanism inside the compression chamber of cell #1, and ONLY cell #1!!!

However, this is best realized in a 1:3 application. You were speaking of a 1:1, making the scenario moot really. But in either event, you should be able to finally arm the flux capacitor properly.

Hope this helps!

I like Steven Hawkins. It would be awesome to sit down and have a chat with him.

[jpoprock]

Heck yeah! But what on Earth would you talk about? He's one of the greatest living minds of our time.

"So Steven... Have you ever spelled the "F" word on your little Speak and Spell there?"

Or better yet:

"Why do people buy MA batteries?"

Or my favorite:

"Which brand of Lipos are the best?"

Many things. A few new theories that I have in my head driving me crazy. His theories and what he thinks about other's theories. How the hell can I create a light saber. What are his thoughts on the world today. Common things like that you know.

[jpoprock]

I'm just teasing u guys for being way smarter than me. The conversation turned "tech talk for scientists" and I had to laff at how over my head it was.

However... If I knew I was going to meet him and get to talk, I'd come prepared, trust me. I watch a lot of show about the universe, supernova's, etc. I even read one of his books!

I did sorta follow what u were talking about to a degree. It's probl all Alien in origin anyway!

I hope u eventually get the answers yer lookin for man...

I heard today from an engineer that battery's abilities (e.g. capacity) are doubling every two years, so it wouldn't be a problem for the car he's designing now to reach 500 km range in 2012 or so.

I was thinking about the last four years with LiPos and that good 30C cells have been around for about two years now... and most importantly, that I don't see a big increase in energy density. So my conclusion is: This is BS. Such an improvement could only come from a new technology, but I don't see it happening.

Such a car could've been done already. The technology has been available since early 2000. I sent my idea to a few of my client's to give me a rough idea of how far the vehicles I have in mind would travel. They said it would be able to go from New York to California and probably back. This was without one of the key components of my design. The new technology we read about mainly comes from people trying to get the most money for them. Look at A123, they have yet to show a profit, have patent issues, place to manufacture them and only 2 commercially available cells which are all 30C. I can get more cells done with a higher C technology and I'll be trying 2 cells, but mainly for our hobby use. I will also rub them in the A123 investors to see what they'll say.

An electirc car is what I've been dreaming for years. Forget the inter-transition Hybrid vehicles, it's a mule carring its both parent horse and dunkey in it's cart. They are not likely to have "next generation hybrid"

I am planning to convert my VW Bora(called Jetta A4 in America) to electric when someday it's engine fails if there's still no decent electric car available. Any good 1/1 conversion kit vendors you guys recommend?

I'd like to do that with a SMART car since they're so small and light. Once I take out the engine, tranny, fuel tank, and other assorted crap, it would probably be light enough to either make a hole in the floor a la Flinstones, or slap a set of bike pedals on it.
