Omnigen: Providing electricity, food preparation, cold storage and pure water using a variety of local fuels

Hossain, A.K.; Thorpe, R.; Vasudevan, P.; Sen, P.K.; … - In: Renewable Energy 49 (2013) C, pp. 197-202

We describe a polygeneration system that can run on neat plant oils, such as Jatropha and Pongamia, or standard diesel fuel. A prototype has been constructed using a compression ignition engine of 9.9 kW shaft output. It consumes 3 L/h of fuel and will produce 40 kg/h of ice by means of an...

Electricity and potable water from a solar tower power plant

Rheinländer, Jürgen; Lippke, Frank - In: Renewable Energy 14 (1998) 1, pp. 23-28

The cogeneration of electricity and potable water utilising solar energy is studied, assuming solar tower power plants with the open volumetric PHOEBUS receiver. The results for alternative plant configurations show that the water production cost is about the same or even lower than the cost of...
