Concentrated Solar Heat in Developing Countries

Concentrated Solar Heat in Developing Countries

The largest energy demand in many communities is for producing heat, for example for cooking or water sterilization. Using electricity, if available, risks regular blackouts and high costs and wood contributes to deforestation and indoor air pollution.
Using concentrated solar power directly, without the need for expensive and complex components, is ideal for many developing communities energy needs.  Read more »
