Kivu Lake between Rwanda and the Democratic Republic of Congo, contains an enormous quantity of dissolved methane. Exploiting this methane is a fabulous opportunity for the economic development of this region. This gas also constitutes a risk of cataclysmic explosion, as occurred in Cameroon at Nyos Lake. A scientific French and Swiss group studied the physicochemical characteristics of the lake and evaluated the risk of a gas explosion. The Company Data Environnement has set up a pilot station to extract the methane for energetic purposes and proposed the promotion of this gas for diverse applications.

Vitagoat Steam Boiler
Malnutrition Matters, Ottawa, Canada

Steam boiler: Operates on wood or other solid fuels or liquid gas. Steam-injected pressure -cooking can be 10 times more fuel efficient than traditional open fire cooking and more efficient than improved stove-design cooking. Water is heated in an inner chamber and the resulting steam is re-heated in a tube, creating a “superheated steam” that is much hotter than regular steam. The steam is then fed into the cooker. The boiler is inexpensive to build, safe, and can be taken apart for cleaning, which is critical since most boilers accumulate scale on their inner shells and eventually fail.
