"Pulse" gel-cell charge strategy?

why not a peltier cell, heated by a small single flame burner ?

Because the burner requires fairly precise gas flow control and has a strong potential of becoming clogged and corroded. The explosive method is little more than a funnel turned upside-down, with a spark plug at the narrow end of the cone.

Certainly true. However, you can replace a lot of generators for the cost of the copper in a system that has to collect the=20 energy in a few milliseconds.

Is the range of combustible mixtures wide enough to guarantee ignition, or do you have to monitor the fuel/air mixture?

Mark Borgerson

I think I said above someplace - no it is certainly not guaranteed. If it fails, we try again.

Lewin,

I just came across some interesting supercaps from Wima available up to

400F/2.5V. They store 1250J and the pulse current may be 600A. They can be connected in series. Datasheet here:

Meindert

What was known in the trade as an FGC.

GC = Great Capacitor. F = unprintable

Aka a BMF capacitor

BM = Big Mother F = ....
