Ah! Yes. Faster speed equalling lower pressure always seems counter intuitive to me, but of course you're right. So the Turbo rocket stove is born

Look forward to some photos. A couple of questions... Are the slits always open or can you close them off? - Are we free to try this out ourselves?
I saw this video below on YouTube last week. At 28:00 you can see secondary air in the riser.

all our developments are free to use for any builder that not build commercially in Israel and not marketing to Israel and build less then 10 stove at a year.

you can close the slits by let the stove to cool down and press some superwool into the slit. if the slit is open, it automatically adjust itself because the more gas velocity in the port, the more drop in the pressure.

in this vid it's looks like a too cool red flame. the secondary air is into the riser? this is bad. secondary air need to go to the lower pressure zone and flames need to be yellow or transparent.

That's Ppotty. There is a group of them that have been experimenting with gasifiers and rockets for years.

I forgot to talk about open source extensively when in Israel, I regret that now. The whole development has been open source from the outset, which means additions are bound under the same conditions as the original design. Yes, I know there are some examples of development which are shielded but in my opinion those can't be legally enforced. Probably I am stepping on toes now but this is the way it is. According to my opinion, of course.

I'm totally aware that any development is rely on the other efforts. no one here make anything really by himself. it is open source to anybody in this wonderful community of people that try things and share things. I think it can be shielded from the big companies that don't share anything with anybody but can easily take the fruits of our effort and use it to make the big money with no saying thanks.

I saw this video below on YouTube last week. At 28:00 you can see secondary air in the riser. That's the guy who's still stubbornly tries to build real rocket heaters out of metal. Some of those are overly complicated and nobody has ever done real testing on it. At 28 minutes the flames aren't transparent and darker orange, which is a sure indication of overfueling. Learned this in Israel, there was a delay between the view through the top window and the readings of the Testo. Well over 90 % of the time when the guys said something like "Oh no, it's overfuelling again!" or "It's clearing up!" they were quite right. The Testo showed the predicted results 90 seconds later.

but I'm really appreciate your opinion and may change my opinion .I wrote my opinion after discussion with some forum members. the people here divide to 3 types- 1. guys that love rockets but can put only small effort money and time to development and try new things. (99%) 2. guys that earn a living from rmh and put much more effort money and time to development and try new things(1%) 3. peter
the type 2 guys put the effort time and money but should shield the results. not from the type 1 guys. from the big players on the market that can kill them in one knockout. all that 99% can enjoy the fruits of type 2 and 3 freely.

Shilo understand your point of view , I myself have benefited from the work of Peter to build a stove in my house ( I will post the results after the first power ) , but having already a job and a family I can experience a lot . But certainly I would not dream of fruitful work of others to make money . Could you ask for a donation to support research , who wants to can donate .

Actually Potty lines with refractory materials now. He built a refractory riser awhile back.

The issue the guys in the UK have is materials are so darn expensive. And size and weight. That is why many choose metal.

Materials for DIY refractory materials are pretty cheap in the UK.

"2. guys that earn a living from rmh and put much more effort money and time to development and try new things(1%)"
As a person who earns part of my living building rmh, and loves to experiment... i thank you for the permission.
I also like the clarification of 'building no more than 10 per year'. This is a sensible way to distinguish between artisan crafts-people, and businessmen who are more interested in expanding profit margins. Not that there is anything wrong with the latter per se, but it does tend towards hoarding of information.
