[1] This relatively late uptake of apparently long-used innovation means the potential of rice husk as fuel has been overlooked by many for a long time, as well as the obscurity of the Lo Trau designs to the wider world.

The stove is started by burning easily ignited material such as bundle of coconut leaves, newspaper partially embedded in the rice husks or other fuels in the combustion chamber area.

Open fire has four major disadvantages: It is dangerous, it produces much smoke, soot blackens the cookware, and the heat efficiency is poor.

This figure is impressive when compared to liquefied petroleum gas (LPG), fuelwood, and charcoal stoves, which required 5, 15, and 20 minutes respectively to boil the same amount of water.

At the present time both wood and charcoal fires are frequently ignited using kerosene, a cost that would be eliminated with the rice husk stove.
