http://www.woodstovesandbeyond.com/alliance/ is being held here in Washington DC this weekend and ends tomorrow. I went by there (with 3 kids ages 4,9,13) and took a few pictures of the smaller stoves and the more interesting ones . There were no rocket mass heaters at all. There were 2 "biolite" kind of 3rd world camping fire stove displays. Sorry for the darkness, no sunshine today and these were all under a tent.

Image 1329 seemed to be the darling of the show if for no other reason than it had the most promotion. It is called "The Kimberly" from unforgettable fire.
Weighs 56 lbs, heats up to 1500 square ft. Cookstove top, says it burns for 8 hours on a single load of wood (did not say how much wood that is). Optional accessories are " thermo-electric generator, baking oven, Blower fan, hot water coils. Saw a quote online for $3700. Probably without any options. http://www.unforgettablefirellc.com/price-value/

Image 1328 is a bad picture but it had a double chamber which was nice to look at as many were but I imagine that cleaning the glass to be a pain in the arse over time. This is the Wittus Twin Fire wood stove. It claims:
93% efficiency, 40% less fuel consumption with 40 % less ash. (%age of what is unknown). http://www.wittus.com/ One price I see is $5990.

Just got a video in my e-mail, from National geographic, that tells more about this.

Rob, Allen, and others,

Dragon Heaters submitted a rocket stove design (Peter van den Berg's) to this contest originally. We also submitted Peter's batch box horizontal feed design. The selection committee took the horizontal design and not the rocket stove as our entry. They also accepted Peter's horizontal feed design as submitted by Matt Walker.

Then, too soon before the contest, they told us that we would be unable to assemble our heater on-site. We were unable to get the shipping figured out in time and dropped out. Matt's entry did not score well on emissions and efficiency.

In general, the batch box is a lot trickier to implement in an efficient way than the vertical feed J-tube design.

Sandy actually attended the contest and visited with the judges. Her assessment was that the judges were unfamiliar with the j-tube and this was the reason they did not accept our entry. Too bad...
