As is ?
Or do you process it into oil/alcohol ?

I take it you mean maize rather then wheat

I find it hard to compute the idea of using food for fuel. Back in the mid 2000's growing crops for bio ethanol was a contributing factor to food poverty and inflation in poorer countries.

I suppose that at least with maize you've got a six foot stalk, all the leaves and a bunch of cobs to use.

Ah, Wilkipedia for more info

I do not know the way just that you can, wikipeadia confirmed it is called corn ethanol, i know about it because of the cobb barbeque or outdoor compact cooker, they of course sell bricks for them, but in the african bush they use corn.
