There are certain tricks in life that you can use in order to turn normal things, like building materials, into amazing devices. If you too have some concrete or cinder blocks at your disposal, we will show just how easy and fast it is to make a 4-Block Rocket Stove. The secret behind such a simple build lies in the design of the block itself. Actually, there is no build required whatsoever, only a clever positioning of the 4 blocks of concrete. With a total cost of little more than $5, this way of making a DIY rocket stove will prove extremely efficient. Very little fuel, meaning twigs, leaves and small sticks is necessary and has shown to be resistant to harsh wind and rain. Watch the video below to learn how to put it all together and how to cook with such a DIY device. The resulting food will taste great!
We stumbled over here different page and thought I might check things out.
I like what I see so now i am following you. Look forward to checking out your web page yet again.
The “one” open ended block is not readily available. I checked Menards, Home Depot, Lowes and some smaller places. None of them carry that block.
Answer: sledge hammer.
Ive heard that some bricks pop or explode under heat and fire, are these bricks you are using fire bricks.
Highly insightful and applicable junk. I concur with yourself on this area of interest.
Thanks for the idea, this was fun to try… I used single cell blocks at a total cost of $2.65. I cut the side wall of one blocks to create the opening to the chimney and used that cutout as a door that controlled the airflow into the burn chamber. Uses 1/10 the fuel a traditional fire would and gives great heat control with my makeshift door and puts all the heat where I need it under a single burner. Next…. a Pizza oven!
Good idea for emergency type use . However , I suspect that using clay blocks would be stronger. I am told that they withstand heat.
