A perfect example of the superiority of communism/socialism. Not having to serve the fickle needs of the 'customer', it is free to develop the best possible product based strictly upon utilitarian and aesthetic values. The Yugo is another fine example of this. How did that wonderful system fail?



The soviet capacitors were probably BS, like the 100mpg carb. Using the post communism business model (still very strong here in Kosovo), they sold a bunch, got rich, and fled before people could come back and ***** about it not working.

The ultra-capacitor that the Russians developed for cold starting trucks is no good for sustained current. It was used in conjunction with a battery. It could be charged from the battery when the battery was too cold to provide high cranking current and then the capacitor could deliver it in a short burst as needed for starting. It's being developed in this country by KBi in Illinois.



Although nuclear power is needed as part of the mix, photovoltaics and windpower are the cleanest available sources and they have the advantage of being sources you can just install on your roof.



The GPR50 is pretty, but it just doesn't provide enough range/speed to be a practical commuter. Check www.21whells.com for how to build your own electric bike that does.

I have an early type; a stealthy jr-trailbike. It is well engineered/costructed and has power.

Yep what you describe is the basic DC response of any capacitor.. i.e. it's impedance becomes infinite (open circuit) when the capacitor gets charged with a DC current. It will then discharge when the original dc current source is reduced or removed... The impedance of any capacitor is a function of the inverse of the current frequency.. Thus as the current frequency approaches zero i.e. a DC current, the impedance approaches infinity i.e a open circuit. Basic Freshman circuits surprised seruzawa didn't speak up something a tech should know..Probably doesn't know anything though about LaPlace transforms.. i.e. probably one of those freon techs... Trouble shoots electronics's with a freon can..

Hey wait a second. The Soviets made some things pretty good. The AK-47, the SU-27 and ........ uh........ er......... omigosh look at the time. Gotta run.

Educate me.



Describe the LaPlace Transform to me in layman's terms.



No Googling.

First you need hipwaders and a huge shovel.

Coolness. Performance be damned... for what appears to be an early prototype it shows promise. By the time electro-cycles mature in 8-12 years, they'll likely put smile on any acceleration junkie.



By 2012 I want my Mr. Fusion model.

So much for your "engineering" education. Actually any engineer who had circuit analysis would know what it is.. You are the fraud...

So much for yours.



You still haven't addressed my request.
