Space Heating For Free, Forever

Most projects I design are fairly standard rainwater or thermal solar systems, but every now and then I get to design one that is far from routine. One such project involved space heating a small master bathroom for a local couple who cares a great deal about living a small energy footprint.

 

Solar Hot Water — It Just Makes Cents

A few winters ago my brother and I fixed the solar hot water system belonging to some friends of ours. The piping on the roof had sprung a leak and needed a small repair, unfortunately in the middle of a snowstorm. The longevity of this system (more than 20 years) and the tremendous cost and energy savings enjoyed during that time by the home’s residents truly amazed me. But before I go into those details, let me first tell you a bit more about this system.

Safe Water Through Solar Disinfection

Every 8 seconds, a child dies from water related disease around the globe. 50% of people in developing countries suffer from one or more water-related diseases. 80% of diseases in the developing countries are caused by contaminated water. Providing safe drinking water to the people has been a major challenge for Governments in developing countries. Conventional technologies used to disinfect water are: ozonation, chlorination and artificial UV radiation.
