Development of a new class of single pan high efficiency, low emission stoves, named gasifier stoves, that promise constant power that can be controlled using any solid biomass fuel in the form of pellets is reported here. These stoves use battery-run fan-based air supply for gasification (primary air) and for combustion (secondary air).

The rural population in India does not have access to reliable energy. India has millions of tonnes of unused and available biomass waste. This loose biomass is currently treated as a waste with no economic value. It is often burnt inefficiently in open fields, causing air pollution. However this 'waste' can be turned into a completely environment-friendly source of energy through briquetting.

Biomass gasification is deemed as one of the best ways to power rural households across the world. It is basically the conversion of solid biomass (wood, agriculture residues and so on) into a combustible gas mixture known as Producer Gas. In India, small-scale biomass gasifiers have been installed in various states.
