Replacing traditional open fire stoves, characterized by low efficiency, with improved ones is an important challenge for developing countries. Adding TE (thermoelectric) generators can provide electricity that permits not only the use of an electric fan increasing the ratio air to fuel to...

Six solar-powered air-conditioners, based on four principles (LiBr + H2O liquid sorption, silicagel + water solid sorption, BaCl2 + NH3 thermochemical reaction, and desiccant + humid air open cycles) have been operated in five places (from the low-altitude Alps to a tropical island...

The use of biomass cook stoves is widespread in the rural communities of developing countries. It is important to improve the efficiency of these stoves in order to reduce the global warming contribution. An improved biomass fired stove has been developed in our laboratory and a prototype has...
