Project Bio Solutions has been able to cook rice on their new solar cookers, it is not enough for the orphanage, but it is a good start.
They will also look at the possibility of heating water during the day with a solar boiler, if you want to cook in the evening, the water is already at the boiling point and significantly less charcoal needs to be used.
The next step is to prepare larger quantities of rice and beans, 3 kg of rice and 3 kg of beans. When this time comes there will be another update!
