Rocket Heater + Boil Water  RSS feed

I came across http://www.richsoil.com/rocket-stove-mass-heater.jsp and found it tremendously exciting and started to wonder if this technology can be used to boil water.
Has anyone done any R&D on this. Is it feasible? Are there any statistics available? I am looking for stuff like how much time and energy is required to boil say 1 gallon/liter of water from say x degrees.
Also, is there any design available (either open source or for purchase) which I can use to build my own home rocket heater?

There has been a lot of research into how many BTU's it takes to boil water. How long it will take varies by altitude. You can look this up on line. However, you probably wanted to know how much water boiling has been done with a rocket stove. I believe there is a design on-line somewhere for a rocket institutional cooker made from a 55 gallon barrel. A lot of people keep a water pot on top of the barrel of their rocket stove.

Our company offers a shippable core consisting of burn tunnel, feed tube, and heat riser in three sizes. We have some designs covering how to use the J-Tube cores on our website, www.dragonheaters.com. We have an idea for a unit which would have a cooking surface over the heat riser and a small oven next to it for bread or pizza.

Ernie & Erica also have some designs. You could incorporate our shippable core into their designs.

All of the following truths are shameless lies. But what about this tiny ad:
