Switch to solar with a system built for you. Since ancient times, people have found ways to use the sun’s heat to stay warm or keep cool. They built homes from clay and other materials that hold heat ...

SOLAR HOT WATER pre-heat systems fall into two basic categories active and passive types with numerous subcategories. A passive solar DHW pre-heater is also known as a breadbox heater or batch heater.

As I discussed in last week’s column ("Resilience: Dramatically Better Building Envelopes," Jan. 4), a resilient home is extremely well-insulated, so that it can be kept warm with very little ...

Researchers from the Solar Energy Research Institute (SERI) at the Universiti Kebangsaan Malaysia have developed a new passive technology to keep solar panels cool. They claim their new tech can ...

Heating houses is a major energy suck. Behind passenger cars and trucking, it’s the largest energy draw in the United States. But it turns out homeowners looking to stay warm don’t need to rely just ...

Switch to solar with a system built for you. Solar water heaters work by absorbing sunlight in solar collectors and saving the heated water in a storage tank. Both active and passive solar water ...

Radiative cooling and solar heating from one system, no electricity needed Study describes passive cooling system that aims to help impoverished communities, reduce cooling and heating costs, lower ...

A research team at Korea University has created a passive cooling system for solar panels that uses a water desorption process and endothermic reaction dissolution process. The method is similar to ...

Following the first energy crisis in 1973 there was a rush to heat homes with the sun. It was a tinkerer's paradise, with all manner of solar heating systems migrating from garage workshops to ...
