Solar energy powered Mogogo for cooking Ethiopian Injra

During these last sunny days we have been able to store enough solar energy for baking Ethiopian bread, says PhD Candidate Asfafaw Haileselassie

Tigrai Online - On sunny days people passing by on Gløshaugen can spot Asfafaw Haileselassie next to his test rig on wheels. The equipment with the noticeable mirrored disk is a large solar concentration system with heat storage. With the help from the sun, Haileselassie generate steam at the receiver of the concentrating system and use this to transport heat from the receiver to the heat storage and then storage store it, like a battery. Exactly this technique has not been used before.

When this storage unit reaches 250 degrees, it will keep the usable heat for about three days. In Africa, particularly in Ethiopia where there is a lot of sun, this is very useful. It is a cheap and environmentally friendly way to make heat, he explains, which also gives people more time to do other things than gathering wood for fires and so on.

Haileselassie traveled from Ethiopia two years ago to start as a PhD candidate at the Department of Energy and Process Engineering. Part of the year (during the winter time) he works in Ethiopia where the sun is stronger. Haileselassie's project is a continuation of the research works under the NUFU solar project that concluded this year.

This solar power mogogo is expected to help to tranform Ethiopian cooking to become green. The equipment with the noticeable mirrored disk is a large solar concentration system with heat storage.
