RICE HUSK COOKER J.A. Hazbun, WHO Solomon Is. In the Solomon
Islands, both rice husks and sawdust from the mills are burned
as waste. This is not only wasteful, but causes a nuisance to
neighbouring communities. The WHO Environmental Health Workshop
has tried to develop a stove to make use of these fuels. The
stove is based on an oil drum with the top removed and a hole
5cm diameter cut in the bottom. A length of pipe is inserted
into the hole horizontally, and a grill is placed on the top to
support the cooking pots. A second pipe is inserted during
filling of the stove with either rice husks or sawdust. Initial
trials showed that two litres of water could be boiled in 15
minutes. A cooker loaded with 20 litres of fuel will burn for 5
hours with virtually no smoke. This type of cooker has not been
extensively tested for efficiency. It is intended to use these
waste fuels instead of kerosene and thus save foreign exchange
for the Solomon Islande
