Must see the video of this, hehe. And don't forget heat sinks if you can, aluminum melts at a fairly low temp.

How about compressed alcohol (isopropyl or whatever)? I have made compression powered jets with those (think like a normal butane torch, with some of the heat from the reaction captured and sent to the fuel tank, which causes more alcohol to evaporate and create the pressure)

In the last day, scott and i have decided to make the body out of steel, and get some turbines from an auto wrecker, so heatsinks wont realy be nesisary. the best fuel seems to be propane, as in LPG, because its easy to get, fairly cheap, safe, and is already under presure. in the movie i used hydrocarbon tho, cuz my butane ran out. i got the hydrocarbon from an aerosole can, its the propellant in almost all aerosoles. u just hold the can upside down and spray untill the hydrocarbon comes out, only problem, the exaust is H2O, CO2, and CO, which is poisonus.. not good in an enclosed garage. ill send the movie when i get home from my field comp.

Sounds like a good idea on the steel.
One thing though, hydrocarbons include propane, butane, isobutane, gasoline/petrol, hexane, ethane, and countless others.
That said, many spray cans use propane as a propellant.

I don't know if using a compressed gas is best for the propellant though, your tank is liable to explode if the pressure gets too high (which can happen from just a few degrees of extra heat)

You could say hydrocarbons are any of the fuels which are a chain of carbons surrounded by hydrogens (spelling, yay!)

Dont you love reading on a can, non toxic, non flamable gas, then u turn it upside down, and spray a huge jet of flame out of it...

hehehe.. yes and eploding is a bad thing? na were going to use a nozzel which lets less fuel in so it burns cleaner and hotter, and so there arnt any flames comming out the back.
