In third world countries much of the used oil from engines is disposed of in the ground. This contamination is an environmental problem.
A good solution to avoid this pollution is to use this oil which has a useful fuel value.
The device shown here (shown open from above) can be used to heat premises in cold regions, for drying fruits and vegetables in tropical regions, to sterilize water for drinking or medical purposes, and in cooking. High temperature variants can be used in small scale production facilites.
An analysis of the gases emitted by this device, made by the University of Geneva and the Services industriels (the Geneva public utility company), have shown that the gases have negligable toxic content. The level of carbon oxides (monoxide and dioxide) are at about 10% of the level accepted for vehicle emissions and the heavy metal content is almost immeasurable.
