did you know you can cook using a normal -off the shelf- thermos, the kind used for retaining tea at a hot temparature? i presented the same at the engineering students exhibition and also at the national energy conference. saves you upto 80 % of the heat you would otherwise use to cook the grains. hot stuff.
