Concentrate – Solar flower power

Ethiopia’s ministry of Water, Irrigation and Energy have just commissioned a beautiful solar concentrating power station with a twist that’s perfect for the terrain – it doesn’t require water.


Traditional solar concentrating power station use the water which is heated, creating steam that runs turbines but this system – ‘The Tulip’ heats air. The air is heated to around 1000°C (1,832°F) and this hot hair is used to run a turbine generator producing around 100 kW – enough to power around 40 average homes, but in Ethiopia  that’s enough for around 400 homes due to the lower energy use there.
