>> the hydrazine generator

/anorak on

Jeez, such exotic technology in aircraft. I'd love to get my hands on
something like that, though sourcing the hydrazine might attract unwanted
attention here in the uk, even if you could find someone to sell it to you.

The uk Lightning a/c used an IPN (Isopropyl Nitrate), a fairly unstable
monopropellant starter. Apparently, back in the day, the RAF used to keep
the stuff sloshing around in unsealed plastic buckets, ready to fill the
small starter fuel tank. You can still find the starters on the surplus market
and are light enough to lift with one hand. They consist of a small turbine
and reduction gearbox and generate ~100hp short term. It would make an
interesting project to fit one in a car for instant additional acceleration.

As for the mobile, do it. Reminds me of all the kitchen and garden substances
we used to mix together to make "fireworks" when we were at school. You would
get locked up for years now for that sort of thing, such is the security
paranoia, health and safety, control culture, ad nauseum.

I think you misread the line about batteries in that I doubt if the problem
will be as simple as a duff batch. Sticking neck out, from info thus far,
looks like an overall charger / battery system design issue...
