I know my friend neal (new to the forum) has built these from scratch using cob he may have a few pic's/video's
I can send him the link maybe he might be able to answer some questions.
has anyone looked at waste oil burner's, there very efficient and a fairly easy build.

I don't see how that can be efficient when most of the heat is being blown out through the flue. I think the furnace in the first post would triumph for efficiency because the output of those huge stone rocket furnaces tends to be room temperature - all the heat goes into the stone or into the room.
However it is useful because it is a way to take advantage of bad oils. I think a small oil burner with a radiator might be efficient. I wonder how the rocket furnace would respond to a steady drip of oil?

Here is a rocket stove that I built, it's for cooking on though.
This is the rough brick form with a two ring stove to the right for smaller pots. No cement was used only cob (clay, sand and straw)
It was built to take a 20ltr pot. I think I left a gap of about two fingers around the outside for the smoke to escape. The three stones are for the pot to sit on, maintaining the gap at the bottom.
It may be clearer in this one
Here it is "plastered" with cob, the cracking is probably due to too much sand in the mix. You finish with a few coats of cow dung which gives it a more or less waterproof surface.
Trying it out for the first time. When lit at first it went off like the afterburner on a jet, you couldn't see flames but you could hear them, they were going pretty high as well which made us worry for all the grass roofs around so we put the yellow windbreaker around and it behaved itself.
Note that the pot is fully submerged. This is an efficient system because the flames heat the bottom of the pot and the heat and smoke heat the sides. Cooking times are very quick and require very little wood. Also working with cob is very pleasing, it must be hardwired into us.
On a side note here is a cob house we were working on at the same time.
An interior shot.
Hope these pictures come out right. I'm a newbie

Hello people!
Other materials to build a Rocket Stove Heater Mass is mixing equal parts plaster and sand, a mixture is made and poured, for example, in a mold with the necessary measures, this mixture is proven by my brother, who use it to make a forge to melt aluminum (650 ° C / 1200 ° F).
Possibly also can be used to make bricks.
