The grain rice is produced by the millions of tons a year around the planet, and is considered to be a top staple food. The edible part of the rice is valuable, but a large percentage of the rice that is harvested is the husk, which has been thrown away as useless. Now, a new designed stove will allow the use of the rice husks to be used as a primary cooking fuel, and it burns pretty cleanly and efficiently, and will also save millions of poorer people the expense of purchasing traditional fossil fuels for cooking.

The fan and fuel sit in the bottom of an iron and steel tube more than a yard long. The tube traps the gases the husks release when they're lit - mostly hydrogen, methane, and carbon monoxide - and combusts them at the burner on top of the tube. Users can raise or lower the flame by changing the fan speed. When the husks have burned, the remaining charcoal can serve as a fertilizer for crops. ed.z.: this is slick little unit. Here is a relevant link for further research, looks like you could do a DIY project from some of these pretty easily. Biomass cooking stoves

sounds a lot like our western Traeger Pellet Stoves, but of course the rice husks are a bit lighter weight (per husk, compared with a pellet).

Useless? Just not being sold

I brew my own beer. Some recipes (think of that famous Irish Stout) use barley and other grains that have been rolled or flaked between hot rollers. That's how they get that wonderful eye-candy head! These grains produce sticky proteins that cause "stuck runoff" during mashing. Cure: add rice hulls. This bulks up the mash so hot water can flow through it. The big guys use special spargers with rubber diaphragms to press the water through the mash.

So how come I can no longer find "food-grade" rice hulls at any of the many internet brew-yer-own shops I've frequented? I've had to give up brewing Stout over this, and I'm not happy about it.

I detect a coming surge in the price of rice husks: aerogel and gasification for power plants, small-scale stoves and even beer too. Who would've thought that a little ol' rice husk could do so much?

While it's nice that he was able to do this it would have been far more exciting if it were done without the electric fan or batteries. Batteries are expensive to poor farmers and they will go through alot of them I bet. The fans will be prone to failure rendering the device inoperable or smoky.
