A warm loo roll via Pulsejet, oh yes very good
When i first made this it was in the hope that it would self start without the use of an air supply from a compressor etc as these twin inlet pulse jets are supposed to do just that but this is the 3rd one i've made now and none of them have self started (although i have seen one on net do it so it may have some truth but i bet it was warm first).
So the switches and valves were all there as A-turn spark on B-turn on gas at idle ignition pressure that would self start and C-full beans once started, but as it never self started it was all not necessary but guess it makes it look cool.

The high and low fuel settings were governed each by a solenoid valve and a pressure regulator from and air compressor, This all worked great so had the jet started it self then boom off we go. As to why it does not self start after messing with it i'd say the inlets need to be a little fatter in diameter maybe.The gas was fed to every thing by a flu rail which was a block of ali with 2 holes drilled down the length of it and plugged off the 1/8th taps put in to feed the various bits so one hole fed the inlets to the solenoids from the gas bottle and the other the outlet from the solenoids to the jet. The holes were drilled from opposite ends hence why you can only see one capped off below
So once running it did heat toilet roll up....and smash it everywhere.....and set fire to it........and set fire to itself. So in all a great invention as where else have you ever needed ear defenders on the bog haha. Thanks to all the great ideas i've been getting and i've started a few VIEWERS inventions already so will it be yours on the next batch of invention shows eh.
