Fan Jet Stoves
The fan jet stoves, forces air into the combustion chamber and increases air turbulence for the mixing of the air and gases, which can result in better, more complete combustion than regular stoves but they are not strictly gasifier stoves.
The Philips Smokeless Stove cooking stove fueled by wood, dung, or other biomass. The African Clean Energy (ACE) company is family owned with support from Royal Philips Electronics and the South African Industrial Development Corporation. The stove was designed by Paul van der Sluis, who is principal research scientist at Philips Research Laboratories in Eindhoven in the Netherlands. The stove principle is not overly complicated: air is forced into a combustion chamber at the top and bottom of the stove. Heat then vaporises the wood or biomass fuel and the flame is smokeless once the stove is running. As the fuel burns reasonably efficiently, the stove uses less fuel than a conventional fire. To contain the high heat, heat resitant materials are used. No prices on the website by contact details are available.

BioLite has developed and manufactures camping wood stoves. The BioLite stove was invented by Alexander Drummond and Jonathon Cedar and the company has headquarters in Brooklyn, NY. The picture of the larger HomeStove on the right is only being distributed through pilot projects in India, Uganda and Ghana. The company claims 50% less wood is used, with a 95% reduction in smoke. Innovation extends to the conversion of heat into electricity. The yellow attachment provides users with the capability to charge mobile phones and LED lights. The sales of the camping stove will fund further development of the BioLite fan jet stove product.
