Made in the shade- Passive cooling

We just survived another major heat wave here. People and plants were positively melting. The sidewalks were veritable solar cookers. I’m sure I could have fried an egg on the sidewalk outside my house. I prefer not to crank the air conditioning, so I have been thinking a lot lately about simple ways to cool ourselves and the spaces we inhabit. Air conditioning is the main mechanical means by which we cool buildings these days. However, t...

Low Tech Solar Heating with a Thermosyphon Collector

Yet another great post from the folks at Build It Solar: a simple and low tech solar heating system called a thermosyphon collector mounted in the wall of a garage. It uses the same principle as the solar dehydrator we have on our garage roof–basically it’s just some clear plastic and a heat collector made out of black window screen. If your climate is cold and sunny (think Colorado) this would work nicely. Read the post to see a r...

Looking for the Union Label

We’ve got a bad case of Ohrwurm, a German expression translated as “earworm” and used to describe a song stuck in your head. Our earworm came after a search for union made socks and underwear on the internets recalled a highly catchy ad jingle from the roller disco era, “Look for the Union Label” (youngsters can watch it on youtube here). We looked for the union label and we were surprised to find it via a company c...

Sun Boxes: A Solar Powered Public Art Project

It’s not often that my unused music degree intersects with the topic of this blog, but I got an email from Craig Colorusso describing a neat, solar powered public art project that he’s touring the US with called Sun Boxes. From the description on his website: Sun Boxes are an environment to enter and exit at will. It’s comprised of twenty speakers operating independently, each powered by the sun via solar panels. There is a differ...

Street Signs and Solar Ovens

If SurviveLA put together a museum show it would, pretty much, look like an exhibit currently at the Craft and Folk Art Museum entitled “Street Signs and Solar Ovens: Socialcraft in Los Angeles” which is on view until December 31st. Curated by the Journal of Aesthetics and Protest, this timely show focuses on objects that demonstrate creative, low-tech solutions to the environmental and political mess we find ourselves in. We were pa...

Solar Water Disinfection (SODIS)

Via Afrigadget, a visual explanation of how to disinfect water with just a PET plastic bottle. The diagram, developed by Unicef, pretty much speaks for itself. Too much gunk in the water? Let it settle and filter through some cloth. At least six hours of sunlight will be enough UV to kill bad buggies. Using solar water disinfection, or “SODIS”, replaces the need to boil water, thus reducing deforestation to supply fire wood. Obviousl...
