Odd Metal jars

[metiz]

Almost done with the core jar

[metiz]

Finished the jar. I tried to run it on some alcohol based cleaner. It runs between 1 and 3 seconds before quiting. But even after about 3 runs or so, the water I put in the jacket was nice and toasty

The results were as predicted. The alcohol stuff is pretty much the best fuel I can easily get around here.

Anyone know where I can get some methanol in the NL?

Turns out moderating the fuel increases the runtimes by 50 seconds

here's the link to the video if anyone's interested http://www.mediafire.com/?zvbjemd9r39mdeb

The last run had steam coming from the pipes, fun times.

Wow, this is getting more and more interesting!

I've been running the pot with white spirit and the water jacket full of water. I've ordered the parts for the cooling system. Strangely enough, this thing loves being realy hot! it works a lot better like that. When the water is boiling and gushing out of the tubes, it runs like a dream. Furthermore, I tried adding fuel when it was running using a needle. I placed the needle just inside the internal duct...and it reved up like crazy

I got a bit to carried away of course and drowned it, but still, this has some potential. It means that if you could make some sort of drip feed, prefably under the fuel level in the bottom of the jar, in combination with the active cooling system, you could probably get this thing to run indefinately as well, without the finicky propane system...AWESOME!

Nick, you're the man! 5 free internets for you!

Good work!
I enjoy watching all the details.

Here's a video of me adding fuel when the jar's running

You are welcome mate, looking forward to hearing more of your exploits and seeing the running on gas experiments

Nick,
Do you think it is important that the cooling water be circulated from the bottom of the coolant jacket and out near the top? Or does it not make much difference?

[Nick]

Hi Joe,

personally i set up the cooling so that it would thermo siphon, so i have the cooling pipes- one at the top one at the bottom, i just think its a bit more efficient.

great stuff though Matiz

Viv will recall the tests we did with my version - I did very similar stuff with a syringe and various fuels, if you can get it hot enough it will run on veg oil too , try it

Nick

[metiz]

Haha I'll try tomorrow

I've been mucking about with propane a bit and I've been able to get the same kind of response as with white spirit injection. I can even throttle a bit. Of yeah, I just use a flat 5mm injector hooked up to a no-restriction 11kg propane tank, using only the bottle valve for fuel control. It's all in the wrist

[metiz]

Ha! got it to run on propane! The water was getting to hot, even though it was running though a copper coil before going back in the resevoir. Had to stop it or my pump would die. I'll get a video next

[PyroJoe]

wooohooo man that was fast! video, video, video!

Cool beans buddy!!,

get yourself a heatsink/radiator etc and then...... who knows?? a Reynst jet conference? time trials? fuel efficiency tests?


Well done though mate, looks like the design can do things (run on gas etc) that others have failed to do!!.
The really really exciting thing is that you have proved the design, we can say build it like this and it will run! that's no mean feat!.

looking forward to more updates

Yes, remember it well it was a fun day of PJ testing and the pots ran and ran, I was surprised how well they did run and how fast they made significant amounts of heat.

Hey guys

I've been running this thing all day, inhaled some methanol fumes and I'm realy tired (unrelated!). After moving the coil, I could not get a 2nd permanent run, only a couple of shorter ones. I realy need to get a more acurate valve, the one on the 11kg propane tank's a bitch

Here's a vid, read the description for more info.

I'll see if I can find a small radiator tomorrow
