</blockquote><div><br></div><div>Imagine that we load a small quantity of biomass pellets into a stainless steel reactor no taller than about 8 inches (200 mm). A small fan with a variable speed control would supply primary air at the bottom of this reactor. An electrical coil producing infrared heat would be used to light the pellets. The lighting would take place in less than 20 seconds and would generate very little smoke. The speed of the fan determines within limits the amount of gas produced. The turn-down-ratio is at least 4 to 1. A burner is placed on top of reactor and serves at the same time as the lid of the reactor. The burner produces a beautiful blue flame that resembles that produced by a modern gas stove. When the process would be finished, the fan would automatically shut down. The reactor is emptied of biochar, and it is eventually sold as a soil amendment. It has a greater value than the pellets from which it was derived. Such a stove could be operated within a modern kitchen. Of course it would not be the only cooking apparatus there.<br>

If biomass fuel has a relatively high bulk density, if it is uniform in grain size, if it is below 12% in moisture, (in other word, if it's well prepared), it could be gasified or pryrolized in such a manner that it could produce a gas that could compete with the gas derived from fossil fuels that are now being burned in modern kitchens. It's not enough that we design biomass stoves for poor people. We should be using them ourselves.<br>
<br></div>I say to the entire stove community. Wake up. Design biomass stoves that you would be proud to use in your own kitchens. Do not just worry about the respiratory health of poor people. Think equally about the much bigger picture of the health of our entire planet that profoundly impacts rich and poor alike. Every time we turn on a modern gas appliance, we are contributing to global warming. Let us do all within our power to put an end to this nonsense.<br>

Hi Anil,<br>
<br>
Thank you for your article.<br>
<br>
I found that you also have an excellent description of your Lanstove here:<br>
<a href="http://www.nariphaltan.org/kerolanstove.pdf" target="_blank">http://www.nariphaltan.org/kerolanstove.pdf</a><br>
<br>
I'm sorry that our conversation got so off-track, this is obviously an<br>
improvement over the wick kerosene lantern that contributes a lot of black<br>
carbon and soot to our atmosphere.<br>
<br>
At ETHOS this year, Tammi Bond, who just wrapped up an extensive study on<br>
black carbon, identified improving the wick stove as the single biggest<br>
impact on black carbon emissions that we could make.<br>
Tammi's slides are here:<br>
<a href="http://www.vrac.iastate.edu/ethos/files/ethos2013/Lecture%20Hall/Saturday%20PM/2013%20Ethos%20Keynote.pdf" target="_blank">http://www.vrac.iastate.edu/ethos/files/ethos2013/Lecture%20Hall/Saturday%20<br>
PM/2013%20Ethos%20Keynote.pdf</a><br>
<br>
So - improving the lanterns, the lighting, and the stoves are all good aims,<br>
and I'd like to see us do what we can to actually help people in with<br>
improved light and cooking and other energy needs.<br>
<br>
That said, the Chulhas stove is not the best biomass stove we can make. We<br>
have learned a lot about making good stoves since the Chulha was designed,<br>
and it's time for us to bring those improvements to the many households in<br>
India and around the world that need them.<br>
<br>
OK, that said, I'd like to see us get back to making a real difference in<br>
the quality of life of many people around the world. We don't have time to<br>
waste arguing each other, when we can be developing and improving good<br>
stoves and bringing those stoves to the people that need them.<br>
