Also there is a gentleman, I believe he was out of France, and he would use hay piles and mulch piles  of wood chips that were built over coils of poly propylene tubing and had water pumping through the tubing. With enough of the tubing touching enough mulch, it produce enough heat that he did not need to do anything else to get his water hot. And he used it to heat his home by pumping the hot water into his home into a radiant floor type system. He also used it for his domestic use needs for hot water.



Jean Pain. Here’s a pdf download. Really fascinating

This is a great thread ! Thank you so much for your careful documenting & sharing of the build. Would LOVE to see a video of your rocket in full burn - wanna heat that dragon roar ! And what a great score on all those cut-off oak pieces.

Hate to betray my technological ignorance.... but what’s the difference between each of the different downloads ? What equipment requirements are there ? Do I need a certain computer to watch streaming ? Is it limited to my phone, or is there a way to watch on my tv ?

Thanks

Excellent info from Peter Van derBerg himself. Way more complex info elsewhere on net to explain in greater detail, if I can find it  http://batchrocket.eu/en/building#belltheory

As a result, the gases could be pushing back and forth at that port, ebbing and flowing as pressure builds back and forth. Ultimately, the added draw from the chimney helps the gases escape in the positive direction. But, it could be leading to the pulsation Till you give it the extra air flow it needs to push thru

Shouldn't it instead be, each successive port should be higher than the preceding, so gases reach the next chamber entrance before the preceding, so no backflow ?

Hey all, haven't kept up on this for awhile due to life being busy, nor ha I read every comment. So, maybe this was already discussed or I'm remembering incorrectly. But aren't the ports between chambers positioned wrong ?

The drawings show port from chamber 2 to 3 being higher than 3 to exhaust. So stratified gases are trying to backflow instead of easily continuing thru the exhaust path.

Enjoying this project a lot, thanks for sharing !

Curious tho, why all the work for the octagon instead of a circle ? Turbulence ?
