I already had those thoughts -- in addition to the noise, there is the
exhaust, the potential danger of carrying around a flammable fuel
source, and a few others. But, if you take a look at a lot of battery
technologies, they don't inspire confidence either.
But, as an off the cuff idea, it might be workable.

That much power? That would surprise me!

I haven't even tried to start the thing yet...just a little purchase that
I got at a flea market.

Any ideas as to the amount of power? I know that it will run as long
as there is a source of fuel, so it's not a simple matter of watt-hours.

It should be possible to run it on vapors from almost any
petrochemical, including gasoline...
But a truly clean burn is practically impossible without rather
significant control of the burn ratio, which in a retrofit will reduce
its output tremendously.
Alternatives?

As I understand it, conversion of an ICE (any ICE) requires only
a means by which the fuel can be introduced...new carburetor,
and a means to adjust the fuel-air mix. Occasionally the timing
needs to be adjusted. I haven't taken a close enough look at this
thing yet, to even FIND the carburetor.
Butane is vapor at operating temperatures, right?
Thinking about it, in this engine, I believe it uses a fuel-oil
mix for lubrication. I wonder if a simple conversion is possible
with a system like this? With separate fuel and oil it seems
simple...
