Firewood based stove

Traditionally people use firewoods as fuel. Wood fuel is largely used for cooking and heating. Residents have migrated to LPG stoves for various reasons. These are quick, smoke-less, easily adjustable and maintenance free way of cooking. Still many villagers / hotels are used to firewoods based cooking bcos of cost reasons. There is a small company at Madurai has come up with a firewood based stove that works like LPG stove without smoke. It is possible to adjust the flame etc. I feel this product would get good market in many regions where cost of petroleum products are getting higher.
