If it heated on one side and chilled on the otther side it creates electric curent and becomes a Seebeck generator or a TEG wich stands for thermo electric generator.
There are modules that are sold as TECs and TEGs with TEGs being more expensive because they are build to withstand higher temp up to 150 C while the ones made for cooling ,altough they can be used as generators perfectly,they last only up to plus 100 C temp.
They have an efficiency of just 10% and there are much better alternatives for such stove generators like the Stirling engines generators with 35% efficiency.
Now, if the energy is lost inside a house ,then you might not care about losses from poore efficiency.

TY good info.

thomas rubino wrote:Hi Kenneth;    Not quite sure what your plan is .  Are you building a rocket stove or a rocket mass heater ?
The build parameters are different between the two.  
Rocket stoves are for cooking or rapid short term heating.
Rocket mass heaters are for heating.

So no on a generic rocket(outdoor cooker). I will be making a few of them later for out door cooking.
But I was hopping for RMH for a space heater with some copper coils for water(gravity feed) in door.  
I just grabbed my small pro pain tank(16.4 oz) AND I C RIGHT AWAY THAT IS WAY TO SMALL.
So I went to elders home and thay had a few old coffee can's And I'll try to make one out of it for outer shell. I need to make heat riser for it now :) I was hoping I could use 2-3 of my micro RMH's for heating and gravity feed water heaters that store the water in an ice chest. So the purple is the copper. Will gravity thermal feed allow the top to drop down to a next boiler ? Ore would I have to have the copper coil arown all 3 from bottom to top Any suggestions on how to get 3 boilers/RMH to strore to a water tank ? 3 separate systems ?(6 lines) 3 cold 3 hot to tank.

What materials shuld I use (heat riser, burn chamber) Perlite/cement, fire brick, cob and ducting that I can find at hardware store's. Thees are the materials I can get. I can j b welding tin/roof flashing to the shell too make ic taller. Jb weld can handle up to 500 F/260 C.

Or should I look for old coffee cans ?

I'm sure the rocket stove experts will be along to help you shortly but in the meantime I've added this thread to the natural building thread. I think they might have some suggestions on something better than foam. Enjoy the permies adventure!

Bath house:
I'm going to make this    Just with 10-20 R insulation and maybe some framing(pvc or car port parts) that is easy disassembly. I need it to handel over night snow fall.

roket stove:
I'm going to put it on a piece of ply wood or thickly laminated particale board type of wood with handles to be slightly mobile. I have a part of a 55 drum and some tin sheeting to make the outside shield. Or I can cut a propain taink(cant realy afor to do this) its not the small one but the medium(8lb ?). Does it mater what material I make the burn chamber, heat riser and the gray areas in my picture with ? Perlite/cement, fire brick, cob and ducting that I can find at hardware store's is the materials I can get. I'l be j b welding the tin to the 55 gal drum. Jb weld can handle up to 500 F. Please fill free to edit any of my picture to further explain  ;)

Hi all. I'm new to the site. I hope this is the right place to post.

I want to build a 6x6 shower room/drying room for cloths during the winter. I live in a toy hauler travel trailer. So I want to make the bath house easy asimbeling/disasimbeling. I need it to with stand snow. I'm thinking of making it out of the fome insulation bard and pvc for framing. I also have car port frame left over. I might need to use the carport parts. Any suggestions ?

And for the rocket stove I'm going to make this https://permies.com/t/110574/Mini-rocket-stove-wheels-hot Would this work for a space heater ? Or should I make it out of diferant materials for a space heater ?
I also saw a build that used radiators from a car.    I might use a ice chest as a water tank. I could also just heat a few pots of water. What would be better and/or safer ?

I added a cooking stove section and used TEC modules to make electricity.(also a first) I added a copper coil to heat water. Of course that worked. I’m impressed with rocket stoves and their virsatility. I’ll add a couple of pics.

This is what I want to make. How did you cut the pro pain tank? Would it heat water better if the copper tubing was in the center of the heat riser ? I need a space/water heater for drying my cloths and for shower room. Will this work ? I'l have to look into the power/energy production as that wuld be great for wen power is out.
