Nari: After reading about the lanstove, and seeing the word “heat pipe” above Table 1, I still do not understand how a heat pipe is functioning in your system. The photo doesn’t show much of a distance between the top of the lantern and the cook pot. Can you provide additional technical

From what the installer of the heat-cooling unit (to maintain a room at 27c) said it is heat needed to melt a ton of ice. This based back when ice blocks were used - so he thinks. Only in the U.S. ! Frank From: Stoves [mailto:stoves-boun...@lists.bioenergylists.org] On Behalf Of Crispin

Dear Ron .my interest is on biomass stoves and the ability to feed multiple pots from a single flame. Do you have an application in mind? A place and perhaps pot sizes? Many of the Indonesian stoves are multi-pot with a commercial activity on the first hole and cooking, water warming

Dear Frank In Refrigeration, the energy unit is tons of refrigeration. This is the energy removed from a room when 1.0 tons of ice melts over a 24 hour period. This works out to 12,000 BTU/hr. Kevin - Original Message - From: Frank Shields To: 'Discussion of biomass cooking

Dear Kevin and all, Just for the fun of it.. That is the energy taking 87818 grams of H2O going from a solid state to a liquid state. Solid state must be 0 deg C (?) so it's the energy taking it from 0 solid to 0 deg liquid(?). Like going from water 100c to a vapor 100c it takes 2256
