I'm pretty sure the V-1 pulse-jet flying bomb used a rocket to launch and get up to flying speed. I don't recall whether it was a solid fuel rocket like the contemporary American JATO, catalyzed hydrogen peroxide monopropellant. or a liquid rocket with hydrogen peroxide oxidiser.

Hi Joe, for no (very few) moving parts you need a ram-jet. Or as some used to call a scram jet. It is essentially a pipe with a venturi and a fuel injector. It needs to have air flowing through it before ignition, like if it was attached to a glider or vehicle. Once enough airspeed flows, the injector is activated and the fuel ignited producing thrust. I bet WVO would work for fuel J. Another one of my hair-brained dreams.

Re: [Biofuel] Cross Posted: Fwd: [DIYGasTurbines] Re: I'd like to try something...but first, your opinions (please).
Hi Joe. When you said Pulse-jet you reminded me of something I saw when I was a kid. It was a small jet turbine that bolted onto your cars differential. It bolted in place of the rear differential cover and connected to your fuel and electrical system. As the car ran down the highway, the turbine came up to speed and you could flip a switch and inject fuel into it for a boost. Primitive but effective. I bet one of these would run well on biodiesel. Your pulse-jets are fabulous. At first I thought they were scram-jets but then saw the turbine. Cool. How much to they cost? -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Joe Street Sent: Wednesday, August 31, 2005 1:39 PM To: Biofuel@sustainablelists.org Subject: Re: [Biofuel] Cross Posted: Fwd: [DIYGasTurbines] Re: I'd like to try something...but first, your opinions (please).

Hi Emil; I should have said that is not my page. I haven't built a conventional type pulsejet. I just pulled the link from my bookmarks FYI. I am more interested in the coanda effect and the ferroelectric effect. The problem wih turbines is they are not very sustainable. You have to have deep pockets to play with those things. I want something with no moving parts. (other than phonons :-) ) Just wanted to let you know there are surplus turbines available out there. Good luck Joe Manzo, Emil wrote: Hi Joe.

"You have to have deep pockets to play with those things." Not necessarily. I joined [EMAIL PROTECTED]a few weeks ago after learning that you can get everything you need from a junk yard.

That's a good question Joe. Right now, I'm just collecting information. So, I couldn't tell ya. Since bearing life is a function of load and RPM, it's hard tosay -- High revs and low load.
