Well, all right.
Whatever turns you on!

Holy cow, a Taiwanese PC motherboard company experienced widespread failures of their boards out in the field.

That explains what happened to huge LCD signs we had problems with in baggage distribution system at ORD UA. Spent 60 man Hrs to fix/NOT. The manufacture finally sent tech to help solve problem. Add 20 Hrs, Problem was so intermittent that we figured out it was board level. We are talking 200 total controller boards. We called in an engineer from the PC board manufacture Taiwanese who sent engineer.Another another 30 Hrs, Immediately, SEEING PROBLEM said boards had bad CAPS. To all you United passengers that lost your luggage in Jan/Feb 2005 via ORD. Just blame it on a .02 cent capacitor.

You just need a bank of these:

I bet one will do us.

Some 20 years ago a small splinter aerospace group was working on EMSL(ElectroMagnetic Space Launch)as part of the overall SDI effort. The basic idea is to shoot projectiles into LEO using the vast power of the coulomb force. One of the best ideas that came out of that study was the quenched superconducting rings-cannon; in some 500 ft of cannon length you got the required 5 mps velocity.

Another idea, by a denver engineer, was a 1/2 mile long cannon using ultracapacitors. He likened it to the power of a 5 million person city crammed into a few seconds. The problem then was that ultracapacitors weren’t quite up to the task, but now maybe they are.

Since one pound in LEO is worth 4 KWH, one can see that EMSL could outdo the shuttle by several orders of magnitude as an STS system. Thus, look beyond electric CARS, as ultracapacitor applications.
