When the fire gets too big, then pull the top block back a little so there is not as much room for the heat to rise, then when the fire drops back a little, u can move the block back.

Been there, done that, no t-shirt. The blocks crack because of the heat. Useless.

The bricks will crack soon. Not made for intense heat – but OK for learning how combustion works.

I’m sick of these posts on every page claiming to build this build that for almost no money !!! Be real or at least honest !!!
Those bricks cost 2.50 each and can’t take the heat ??
You need to at least cover them in cob but even then why not make one that lasts ?
that will cost more than $5 and it will also crack upon using more than a few times..just dont do it.

I was thinking the same thing. But you could build something similar with fire brick.

mhmm one could/ a little more assembly and more than 4 bricks, its a basic fire chamber. go a step further add the secondary burn chamber so that the gassification is complete thereby increasing fuller burn efficiency. .

That will last five minutes until the cement heats up and falls apart, especially if it’s a rocket stove. Five dollars for five minutes?

Neat way to do some conservative cooking. I would like to suggest to the video folks that they use something to control the opening size where the fuel is burning. Doing so will help them keep from torching their tuna, or grilled cheese, or whatever was in that white bread failure. ?

Ugh, most cinder blocks are made with carcinogenic coal ash, this is not a smart thing to make for cooking.
