I don't get it. Could you go into more detail besides posting what it is. Like how it works? :?

Interesting idea! I'd like to see it done with quicker evaporating fuels like octane. How fast does the alcohol evaporate a combustible quantity of fuel?

Well as soon as it missfires, I dump the old crap out the ball valve, and refill it with new alchahol. I wanna see this design done on full scale!.

With octane the mix will be very inconstant(I mean unless you have a continious spark and exact flow of air).Metanol is the best fuel for autocomb. alkohol can replace it because it's awfull to shoot that thing in a room with CH3OH.

If it’s semi-combustion does that mean that it’s only part combustion? Or do you mean that it’s an auto-loader combustion?
what kind of power do you get out of it?

It's a repeater as it is.manually loaded, but capable of multiple shots in a row.
It's basicly what Rambo did a yaer ago with his full auto combustion.
Only Rambo had a continous spark and a continous fresh airflow..

I was joking I had already figured out that it was not a semi-auto/auto-loader, just a repeater. Hence the “part combustion”...

It's a sure semi! It has mediocre range for a combustion mini. Ohh well, back to the drawing board...
