Stainless Steel Grover Rocket Stove

Anybody have one of these, or ever used one?
Impressions?

I've not used one.

It is a cook stove, not a heater for warmth. As a cook stove I suppose it might last as they claim. Cooking is of short duration, so maybe it'll hold up. But 10-years? That's a lot of cooking at 2000 F in the fire box.

I certainly would not expect it to hold up as a heater (which it is not being sold as, to be fair). 2,000+ F for such extended times, I would expect the metal to break down. But others who have actually used metal will be a better source than I am. I just know I've read of enough metal failures, I'm not going to waste my time even trying it for heat; I might for cooking, if I can get the metal cheap.

John Smith : My advice save your money, I have have milti-course melts prepared on a 3'' Cast iron street ell ! And made adequate Rocket stoves out of a # 10 Can
and a Rainwater drainpipe Elbow and Dirt ! And have a part time use Rocket stove made in a 5 gal bucket with a clay vermiculite Core its about 5-6 years old !

_ # 10 cans are steel, depending on their contents they my have several different types of lining , as you will be insulating with dry dirt , or pumice, or a Clay Slurry
and perlite mix , and you will be using it outdoors this is pretty much a non issue ! 4 th' Craft !Big AL

I have seen straight perlite or vermiculite used as insulation, in many of the videos.
What is the advantage of using a clay slurry and perlite mix?
Thanks for the insight...

With inside metal tubing for the heat riser?


Metal is doomed!

Ok, why is the metal doomed?

J.S. : Please do a Google Search for High Temperature Hydrogen Attack and Hydrogen Embrittlement ! Basically Bivalent or Divalent ( 2 atoms )
Hydrogen is such a slippery gas that it can leak out through the micro-pores in the walls of a Glass Container!

At the temperatures experienced within the walls of any Rocket Space heating Unit Monovalent ( Single Atom ) Hydrogen is produced ! This single Element Atom
is Soooo slippery that it easily 'leaks' into the crystalline structure of all steels, and drastically alters that metals integrity ! (Steam embrittlement )

Here as with all Heating units ( And the presumed interior components of the " Grover Rocket Stove " ) Insulation between the fire and the Metal shell protects
the metal bits !
