New Approach Promises Cheaper Solar Thermal Storage

Written by , on November 5, 2015

Engineers at Oregon State University have developed a new approach, using thermochemical storage, in which chemical transformation is used in repeated cycles to hold heat, for the storage of concentrated solar thermal energy which could reduce its cost and make it more practical for wider use.  Read more »

Coating Greatly Improves Efficiency of Solar Hot Water

Written by , on October 30, 2015

Researchers at the Technological Institute of the Lagoon in Mexico have developed a superconducting coating which they say increases the efficiency of solar water heaters by up to 70%. The coating material is a type of paint, classified as an “ink” because of its quick-setting property, that is built up in several layers. The first […]  Read more »
