<div>Dear Ron,</div>
<div>corn (maize) is not grown on a large scale in the area where we live. Many farmers grow sweeet corn to be sold as whole cobs, which are sold in the vegetable market in lots of 6 or 12 cobs. In that case, the shanks go to the persons in town who just throw the shanks into the garbage. There are of course farmers who grow corn for the grain. In a semi-arid country like India, corn is generally irrigated. Since corn as grain is raised only to be sold as chicken feed, the price is not as high as grain eaten by humans. The corn growers use the shanks as domestic fuel. I do not know if the shanks are used throughout the season as fuel. As far as I know, firewood and dung cakes are regularly sold in the market, but I have never come across shanks (without the grain) being sold as a commodity. <br>
Yours</div>

<div> Thanks again to all for more data. I am getting less certain with time on the availability of corn cobs. Must have a lot of regional variability. Also we need to note there have been a lot of kernels burnt in the US instead of pellets - not very likely in Costa Rica or India. So you would think cobs might have a place as well somewhere besides India.</div>
<div><br></div>
<div> To AD> Are there places in India where cobs might be the "only" fuel throughout a year? Anything on market value?</div>
<div><br></div>
<div> To Art> AD.'s question to you is important. It wouldn't seem that the pigs and chickens would be getting much nutrition from a cob. Might char from them be more important to a farmer in Costa Rico?</div>
<div><br></div>
<div> To Tom> Thanks for the lead on the Anderson's book. My library and google say no copies anywhere in Colorado. If you or anyone think there is something important on char from cobs, I'll try harder on an interlibrary loan.</div>

<div>Dear Art Donelly,</div>
<div>are the cobs fed to pigs whole cobs with the grain or the shanks left after removing the grain? Here in India we regularly use the empty shanks as fuel.</div>

<div>Hi all,<br></div>It has been a busy few days, so forgive me if someone has already made these observations. We have used corn cobs with great success in the <span>TLUD</span> style <span>Estufa</span> <span>Finca</span> stoves. I love showing people our little tiny corn cob charcoal. We have also successfully made a lot of <span>biochar</span> from dried corn <span>stover</span> in our version of the 55-gal drum <span>TLUd</span> style J-Ros. MIT has also promoted both of these approaches in it's Field-to-fuel program in Haiti and Nicaragua.<br>
<br></div>But there is a problem with thinking of corn cobs as a stove fuel: most cobs are used as animal feed (pigs/chickens) and needed for it. Applying a hierarchy or best use: the pigs win! However pelleted or briquetted corn <span>stover</span> mixed with paper waste seems like it has a lot of potential. <br>
