In less than two minutes, you can learn how to build a rocket stove using only cement blocks. Just watch this brief video, "The 6-Block Rocket Stove," for the easy instructions.

The video's clever design for a dual-burner DIY rocket stove uses only six concrete masonry units (CMU), also known as cement blocks or foundation blocks. By stacking the blocks as demonstrated, you'll be able to channel enough heat from a small fire to cook food in two separate pots.

This was posted on Facebook many months ago and I have yet to see a post from someone injured by this. It may be only a temporary solution but it would come in handy in a major pinch. As for exploding from the heat, perhaps the blocks were damp? Older blocks are more solid than these newer ones, perhaps this isn't such a great idea if using the newer ones? Rather than smacking someone up side the head - ask questions and get more info before 'roasting' the idea. One can always put blocks in front of where the person will be to provide some protection from any weakness in the set-up. Make suggestions, maybe give better solutions - don't just slam something. Good grief.

I've used something like this on a little piece of land I have out in the woods. The design was slightly different but made of concrete. I've used it for years to make coffee and breakfast and never had a problem with the concrete blocks they have lasted just fine for years.

cement blocks wont last, that is a one time shot. native stone is what i used when i made my first one years ago. The idea is great, the execution is horrible and this is really very bad info. Cement can even explode with the heat thats invovled. Did the author even try it? Or did she think this was a great idea and set readers up for possible injury? This totally irresponsible.
