Was: Lead Acid battery Model

[martin griffith]

I was googling for "thin metal film batteries", just out of interest,
and found this
http://www.killacycle.com/

But it seems that Boulder TMF cells are no longer made,
They said once

"We have a battery that's a little bit bigger than a finger that can
put out over 1,000 amps of current, and there's really nothing else
that can come close to that."

How on earth could a company who made such a device, go under?

Serious error.
All shortcuts have disappeared.
Screen. Mind. Both are blank.

The investors demanded their money back when they figured out that
such a thing is impossible.

I dont see why it should be 'impossible'. As a school kid I played with
NiFe cells made around 1945 which were about 1" x 1" x 1/2" . Voltage
around 1.2 volts, and could easily melt a 1/8" steel nail place across
the terminals. That would have been around 2-300 amps current, and
these cells would have been at least 10 years old by then ( although
freshly charged ). We are talking 1940s or earlier technology here.
