I know there's a lot of designs to make a 12v supply from a deisel
truck alternator and a push lawnmower engine. You might need a couple
extra pulleys to get it geared down to where it's comfortable to crank
by hand (or foot), but it ought to be possible. The reasons for using
a semi alternator are that the 12v regulator is built in and it
simplifies things; also these trucks typically idle at about 1/3 the
rate of a gasoline engine, they have to maintain voltage at low speed.
You can idle down that Toro and run your rig all night on a gallon or
two, it would seem like running a receiver, QRP rig, or even 100w for
short bursts ought to be possible on a meat powered rig.
