I should do a new freewrite about these things! Or just a post, for homesteading.

Corn Burning Stoves. A fairly recent innovation that is slowly growing in popularity is the use of corn as fuel to heat houses. Although the principle is similar to log burners using corn as an energy source does require a different type of stove. Some stoves are designed to burn different forms of pelleted fuel.
Corn stoves, as well as wood pellet stoves, can keep an even temperature, unlike traditional wood stoves that fluctuate. You can fill the hopper, set the temperature, light the fire and pretty much forget about it for 24 hours. Wood requires much more maintenance throughout the day to keep the fire going.

Runs 24/7 ....? Only if my mom kept feeding it, way back when:

Shelled corn is readily available at a store near you (usually a feed and seed type store). Customers have reported heating up to 2,000 square feet with the model 2100 Freestanding Corn Stove. Room air is continuously filtered and re-heated so that comfortable heat builds up more and more as the corn burning stove runs 24/7!
