Hi,
I first learned about rocket stoves in Holmgren's Retrosuburbia book. I watched a few videos online and built a small rocket stove out of tin cans. It works alright, but it's poorly insulated and will most likely not last long.
I've been trying to find the original blueprints or specifications to built a rocket stove properly, but I've failed so far.

What I'd like to find is a simple rocket stove design, for cooking (not mass heating), with appropriate dimensions and some suggestions for the materials to be used.

Thanks a lot in advance for your help.

Paul Wheaton, the owner of Permies, produced a video series that is available to purchase, that is the most in depth resource available.  There is a ton of free information here as well.  

If you can weld, a simple square tube (over two inches x two inches) will work.  The top leg of the L shape (chimney) should be at least twice the length of horizontal leg (firebox.)  That is it in a nutshell.  The firebox can be at an angle 35 to 60 degrees off the horizontal is you wish gravity assisted wood feed.  A J tube design can also be used with a vertical firebox connected to the horizontal combustion chamber described above with the L shape design.

If you don't want to weld, the same design and dimensions can be made out of dry stacked or mortared fire brick.  The dimensions are not critical, just make sure you have enough vertical chimney to combust the gases completely, as that is the main advantage of the RMS.

Thanks for this answer, I didn't know about those DVDs. In the meantime I spent a little more time searching for information and I found a series of books on the Aprovechio website : http://aprovecho.org/publications-3/ . That's what I was looking for.
