DVD demonstrating a rocket stove using very little wood to heat up a hot
Claude Taylor: Man this is awesome. I like this idea. Thank you for the video
Richard K.: "A copus tree that regrows sticks all the time" "you don't have to kill any
Heck with the rocket heater i just want to farm these copus trees. I can
see it now hundreds of trees that just regrow sticks. I'll never have to
pay for heat again.
Alex Newton: might be better idea to put barrel vertical then you can drain the coil if
its not being used in the winter
Juan Manuel Garcia Bellande: Hi,
What's the material inside the barrel?
Fire Starter: This is great, thanks for sharing.
Main Street Firepower LLC: Check this out for your backwoods cabin
or bug out retreat. Don't forget you can
find more tips, tricks, and survival info
with us. Check back with us often.
dieeeeeeeeeeego: Sincerely, I don't get it. Why isn't the fire growing by outside which is
the path with lower air-resistence, instead of by inside. Also, what with
the chinese house? Are you filling your house with smoke or hot CO2 ?
Either way is not a good idea ! Or maybe i am not understanding
k2chris1983: I was wondering how hot does the water get?
cheekyfool2u: Does he say 18 meters or 80 meters of copper pipe? I wonder what sized pipe
009kronos: Wow! A clip in htis video was about how Ancient kings used rocket stove
technology to heat their home. Fire in the basement. Where can I find more
videos illustrating this “ancient kings” method of heating their homes???
Very much appreciated. D.T.Grosz@gmail.com
Dan Murphy: there is no good plans for a water heater design yet, still in the works, I
followed this one & I think it way under performs.. “my opinion” I will
post video of mine (for Free) if it turns out as good as I hope, will be
hopefully completed in December or January.
paulaontologist: Check out permies(dot)com. They have long threads about rocket stoves.
Someone on there will be quick to help you out
Glen Bradley: thats a great idea! rocket stoves are da best!
Walter Jacques: Are you saying that the barrel is full of water? Seems like it would
explode when it boils.... I love the idea!
angryadrien: Great video!! do you have any video or photographs of the construction of
this rocket stove? I'm curious to see how you support the drum inside it
and how you shaped the interior. Is the copper completely contained within
the drum or does the copper come in contact with the burning flue gasses?
Have you tested the temp of the water coming out? Thanks!!
ega278: What did he say in the beginning about sticks for a "coppus tree"? What's a
coppus tree? Where is it native to and what growing zone?
ciucinciu: cold water in, hot water out, you cant explain that!
MrDavidwilson86: Great idea another way is to wrap the copper tubing around the burn chamber
before insulating it. or even better if you could manufacture the tubing as
part of the burn chambre!
KoruEcoSpa: Go Geoff ! You're the best, Thank God for you in the world.
dale hodgins: Have you considdered blackening the cob so that the sun can pre heat the
cob? And what about a solar pre heater, something as simple as a black
barrel? I like the styling. The name of the farm could be written on it and
it would look like a small town water tower.
mreisma: there is pressure release, it lets out steam and water overflow. they
didn't show the other side.
cdimmm: i'd put that puppy in the house.
Hussein Hobbalah: great. this what i was looking for, for years........
Wayne Boyer: Where did he get "18 versus 80" "Frank" says it at 30 seconds.
yellowdog123456: I like everything about it. I do have a question or two though. Is that
white mass all about foam, concrete...what? Also, is there a limit to the
size? Most of all how to do I get to you for (glad to pay for your time)
advice as i go.
JohnQPangolin: It would be a LOT more efficient if you simply fed the hot gases through
the vent of a normal, gas, water heater. Newer water heaters are extremely
efficient and have convoluted gas paths that extract most of the combustion
heat. Of course, a solar water heater beats this rig completely. No work,
no fuel, just a big tank and a solar collector.
MrDavidwilson86: hey does the barrel have to be sealed? or vented for pressure release.
Saeid Momtahan: @dieeeeeeeeeeego El rason para el aire going up is that hot air goes UP,
right? Aire caliante no fue the path of less resistance, but simplimente
UP. Entiendes ahora? Es un design mui sensio! Saludas desde Iran (-:

61juliette: A coppiced tree - that is a tree cut at the base for a crop of sticks.
cdimmm: what did you make the thermal mass out of??
Jimmy Gann: not sure I believe this ... why no construction pictures ??
Paul Mays: the actual design does include a steam blow off, this video does not get
into the details.
Dan Murphy: your not understanding
vention4wh: Dang it! The video still isn't available yet. Urban permaculture could
really save our butts here in the city.
Wallabytrack: Excellent Mate!
Jamie Bracken: Well going off the brief description its hard to assess just what is going
on in there as they only give the basic of the mechanism.
kbbacon: Looks good, too!
Erica Wisner: @robertsmi9 I wouldn't dismiss the possibility of boiling the water in the
barrel; the chimney appears to vent smoke past the barrel, not steam from
the barrel itself. Rocket stoves can boil a large pot of water quickly.
Vents or safety plugs good. (Though if it's only run on demand, the flowing
water in the coil may carry away enough heat to prevent a boil.) Looks
clever and effective to me, and not as risky as other home systems I've
seen. No wonder people are talking about Geoff Lawton!
yellowweaverbird: send me your email id. will send you photos of my very simple water heater.
It is the best design that I have come across yet. and the technology is
very old and traditional in India. not one water heater design that I have
seen on youtube can match that. The above example is an overkill and
totally not necessary.
reyjalapeno: How many meters of copper pipe in the barrel,please'thanks
Jeva157: Where can I get details ;)
TheGuilhermeandrade: Thanks for sharing it...
pauluminous: @angryadrien This video is a part of an article, if you follow the link in
the description bellow the vid it will take you there.
William Saltzmann: The only concern I have with this is the absence of a pressure release
valve for the main body of water being heated. A open type of tank would
correct this problem, but a closed tank without a pressure release is no
less than a bomb. Water boils at 212°F which is easily obtained with this
robertsmi9: @MrDavidwilson86 The barrel would not have to pressure release because of
the chimney, there willbe no pressure. And i would thinking sealing is not
an issure because it is incased in thr structure where rain can not get to
