Steam Generator

Here is another version of the original steam generator. It's much more simple in design.

I need to build one of these... or something of a flavour of my own... :)


have a good weekend!

Steam Engine

Thanks Mark for that video!

I wonder if we can buy these for our house and how much it would cost?

Thanks again,

Steam Generator

Mark your funny! There is a very small chance that some sort of cold fusion might be happening and in this way the device would not be violating any laws. Also remember that these people did spend an awfull lot of money to have the unit tested by credible people. Again it doesn't matter if it's over...

A steam generator with possible over unity

http://www.rexresearch.com/schaeffe/schaeffe.htm I found this very interesting. Even if it doesn't put out more energy than it takes in and only is %98 percent efficent it's still a tremendous break through. I wonder if the concentration of natural occuring heavy water may have anything to do with ...

Don't try

That fire Oxygen triangle does not apply to certain compounds like Acetylene. If you used Acetylene it would turn into a hand grenade. The pressure jets use a spiral SS tubing in the CC itself, to bring the propane temperature up really high before entering the intake. Good luck and lets see some vi...

Natural Gas

It does seem to have a good range of burning. Between 5% and 15 %. Although it must be stored under high pressure, unlike propane. Almost any fuel will work so you could definately use it, and if you have an abundent supply well..... Go for it! Here is some info on Propane Typical Properties of Prop...

Pulse Jet Start Help

Hi Sedgewick, It would greatly help the rest of us if you could upload pictures of your new PJ or some sort of construction drawings. If you not 100% sure that you PJ has started then it hasn't. :) These things are so loud that there is no mistake when they are running. You mentioned that when you t...

Lady Anne 07 Testing

Hi Larry, That's great news that you were able to get Uflow to run at 370 Hz. I'm in Japan at the moment. I'm not sure if I even have Uflow on my computer to test what you must have done. There are of course only a handfull of other varibles or options. So unless you tell me your secret I might just...

Lady Anne 07 Testing

Hi Larry, I was playing with an online resonance program. http://hyperphysics.phy-astr.gsu.edu/hbase/waves/opecol.html#c1 And if it's correct your PJ is 0.546 meters long and it would appear that it's acting like a closed pipe resonator with an average temperature of 700-800 C. At 800 C it's right a...

Lady Anne 07

Hi Larry, Just a correction. I ment Uflow instead of Nudis. I put your Lady in Uflow and did some testing and I could not get the frequency up any where near 370 hz. I did get it up to 266 hz, but that is still a long way off. I even closed off one end and did not even use the intake. I'll have to t...

Lady Anne Test

Wow Larry, Your lady there is running between 350 and 370 hz. You can hear it moving through cycles. It ran at 370 hz at the end of your video. I'm amazed at how high the frequency is. I would be interested if you measured the frequency of the tail pipe in Nudis. I just use a ruler on my monitor and...

Lady Anne 07

Hi Larry, I was wondering if you still draw your Lady Anne in Nudis by having the intake infront of the CC, or have you found a better method? Of course I always have a concentric intake on my mind, so at some pointe could I have your permisson to try and build the lady Anne with a concentric intake...

SS Lady Anne 07

Larry thats Awesome!

I wonder how much the placement of your fuel injector will affect the running when using your low pressure propane setup?

Great job and can't wait to see some video and numbers.

Larry,

I'm glad that you are so close to your new design.

I'm sure you'll nail it down on your next run.


Your success make me want to go back to my concentric designs and impove upon them. I guess not before I get Eric's big one going well.

I'm happy to hear the good news.

Congrats...
