How to make a heater

I live in a place where no Winter occurs.
Please don't tell us you live in hell.

Estes rockets: LOVED those things. My kids flew them all the time. My little girl was crying because the bigger kids could catch the rockets when they came down and she couldn't. So I set the timer and took her into the field, just the two of us. Rockets had been coming down in this area all day. But when we (my daughter and I) were out there the wind shifted and the rocket started to drift to the north. I had to scoop her up under my arm and do a 100 yard dash. We just got there in time for her to catch the rocket. She started crying all over again. So I asked "What's wrong now?" And she said "Nothing. I'm happy."

I want to use an HHO generator and a copper tube to direct the flash up the exhaust of the motor to ignite it. It's an old thought I've been having, and maybe one day just for the sheer heck of it (don't want to offend R!f@@) try and see if I can get the motor to ignite. Maybe when my grand daughters get older I can take them flying. I'll have to rebuild my launch timer control too. Had a nice one. Would count down for 30 seconds. At 5 seconds it would start beeping a car horn. The horn was connected to a car signal flasher. When the rocket was launched the timer would shut down and the horn would stop. WAY COOL. That was back in the 80's. Used to make home made bombs too. NO WAY I'm messing with that stuff today. Don't want to go to Club FED.

My son and I shot off his first Estes rocket on the sports field behind the middle school. The wind shifted for us as well and the rocket drifted a couple hundred yards to land in the school roof. He was so crushed, he never made another rocket.

Here's an AWESOME heater. So hot it can ignite an Estes Rocket motor (in theory) (many adjustments will need to be made to the design, the chamber and the timing of the HHO switching on and the ignition firing).

I could have told you that would happen. ;) Except in my case it was the high school. :)

Brother-in-law shot it off in his back yard. Came down and tangled in the power lines. Dip!

I would rather have a model rocket caught in power lines than what happened to the hot air balloon, across the street from my old apartment. They were stuck in high tension lines. I never knew what happened to them as I had to go to work. When I got back they were gone without a trace. So either they were rescued or they completely disseminated. ;)

Heater? We have had temps over 30 Deg C every day for the last four months at least. Had one day at 27 Deg C. Don't need no stinking heater!

Tonyr1084, your little "gadget" that you drew . Just what is it meant to do? Is it meant to provide a constant flame or just a short burst. Could it really be used as a heater?

It's meant to be a short burst of intense local heat. To ignite an Estes rocket motor. Used to fly them with my kids a long time ago. Always wanted to build something that could shoot a flame into the nozzle instead of having to insert an electric match and HOPE it's in well enough to light the motor off.

The more I look at the drawing the more I want to build it. I still don't know if it will work, so I'll probably start with the hydrogen generator and the combustion chamber. Use a spark ignitor from a gas grill or something to initiate the reaction. See if I don't blow up the chamber. Hydrogen Hydrogen Oxygen (HHO) burns pretty darn fast. I've had open containers (no lid, no back pressure) with fomenated HHO and put a flame to the foam only to get an energetic PAP! Loud enough even to make the ears ring. So I may end up building something that self destructs unless I provide extra ventilation for more of the rapidly expanding gasses. The good news is that when you put flame to HHO it turns back to water. (vapor)

Just googled "Estes rockets"
That is cool. Like I said, I fly it here, certain people will get scared and I will be off grid for a few months.

Yeah, that's the world we live in today. Too many frightened people. And I understand that. I USED to make home made bombs. Hell of a bang. But haven't made those since the 1970's. Make one today and get caught with it and you're "off the grid" for quite a while. Even if you were just making it for fun. Which is all we did.

One guy saw my home made - and he started laughing. Said to him "Wanna hold it?" He said "Sure! I'm not afraid." So I told him he could hold the next one, this one was going to be set off in the middle of the street. BOOM! Standing a good 75 feet away (22.86 meters) and the concussion was felt all through your body. Needless to say he wasn't willing to hold the next one.

And I only learned how to make them even more powerful. And no - if anyone asks - sorry, I don't share bomb making secrets.

BOY DID WE GET OFF TOPIC!

Battery powered heaters: Yeah, that's what this thread is about. Um, no. Don't build that silly little thing. Nor should you build bombs.

Tonyr1084, that looks awfully complicated just to fire up a rocket. Maybe NASA would be interested. My thought would be to use a small oxy/gas torch on a stick. I guess one would need to hold it under the rocket.

I wouldn't want to be under a rocket when it is launched :eek:
