WOW! Amazing: A Rocket Stove

rocket mass heaters in a nutshell:

  • heat your home with 80% to 90% less wood
  • exhaust is nearly pure steam and CO2 (a little smoke at the beginning)
  • the heat from one fire can last for days
  • you can build one in a day and half
  • folks have built them spending less than $20

the verbose details on rocket mass heaters:

I Learned About This

a while back from a book I have called "The Hand sculpted House" Wonderful book! You can usually get it at half.com for cheap. It teaches how to build lovely homes hand made with cob.


Would you look at that

Put 4 wheels on that sucker with a torq converter and a pressure chamber with turbines and we have ourselves a car that runs on hemp stalks.
In fact u can use hard drive disks to generate electricity with it.
Use can burn corn stalks and even wheat.
No more gas, and you can grow your own fuel.
let's start a project to make a car out of this
I'm going to work around with my autocad now.

Paul Wheaton is a maniac!

The man behind richsoil.com and permies.com is Paul Wheaton, I believe. Have a listen to his several interviews with Jack Spirko at thesurvivalpodcast.com; I think you will be stoked! (sorry, can't help but make a pun :-^ )

I haven't built a rocket stove yet, but I have built a couple of "hugelkultur" beds (aka, 'woody beds') and am quite happy with the results after only two years.

Practicing permaculture techniques has changed my life more drastically than Dr. Paul's ideas and speeches ... that's saying something!

rocket mass heater

I slept on the RMH shown (brown with on-point tiles set into the front). It was almost too warm.

Engaging in advanced citizenship

We plan to heat our fish tank with one.

Aquaponics, rocket mass heater, fodder fed cows and chickens, permaculture (you will grow your own wood for heat), and Carl Miller's lessons on the Constitution are about all you need to be free.

Love or fear? Choose again with every breath.

How much are these?

How much are these?

its a diy thing

Its not been approved by the state, so you really cant buy em. Apparently with a few people you can make it in a few hours with very inexpensive supplies..

Great post, masonry fireplaces, Kalchelofen like design

This looks like it's based on the Russian/German masonry fireplace, a design thousands of years old and used for both cooking bread and heating the home, they can be very expensive to build. This redesign makes them affordable. Wish I would have seen this before I bought my wood stove. Check out the Kachelofen pics, on this site.


Rocket mass heaters are

Rocket mass heaters are pretty good and very cheap and easier to build for most DIYer but masonry heaters are more efficient and do not need to be constantly fed and have a smaller foot print. The Flues snake through the masonry rather then lay out on the ground like a rocket mass stove. Although they can have a bench.

A masonry heater could be built as cheaply as a rocket mass stove out of adobe but still need the firebox built out of firebrick.

End The Fat
70 pounds lost and counting! Get in shape for the revolution!

Get Prepared!

Rocket stoves are awesome

I have built a few and absolutely love them. I would like to do the mass heater idea but I find cob very annoying to make and work with. I'm considering using high-heat concrete or stones. Here's my stove https://www.youtube.com/watch?v=tZzy3LNe9Gs
