DIY Solar Space Heating

...here in Los Angeles. In the northern hemisphere it’s time to consider heating. The always useful Build-It Solar blog has a detailed link to a DIY solar space heating system in Virginia (pdf). Collector panels mounted on the roof heat a reservoir which is circulated through a floor-based radiant heating system. It even has an Arduino based data acquisition component that tracks performance. There should be a DIY Nobel Prize for this project...

CooKit Solar Panel Cooker

I’ve been experimenting with a nice panel solar cooker for the past week and, so far, the results are impressive. Called the CooKit, it was developed in 1994 by a group of engineers and solar cooking enthusiasts associated with Solar Cookers International and based on a design by Roger Bernard. It has a couple of nice features: It produces ample heat to cook rice and simple casseroles. When you fold it up it takes up no more space than a...

Build a Ghetto Solar Cooker

Using crap we had laying around the homestead, SurviveLA fashioned a solar cooker based on plans from Backwoods Home Magazine, the Dwell of the Ted Kaczynski set. We just substituted an old cooler for the cardboard boxes, and we finished it off by using one of Los Angeles’ ubiquitous abandoned car tires as a cradle to keep the cooker oriented towards the sun. It ain’t pretty but it works. In our first test we reached 160º inside the...

Camping and Solar Cooking

...hese sittin’ around type of trips, or even a lazy Sunday afternoon at home, are the perfect occasion to deploy a solar cooker. Best of all you can build a solar cooker yourself for pennies out of cardboard and aluminum foil. For some foods, such as rice, it’s actually easier to cook with a solar cooker than it is on a stovetop. Put some rice in a pot, place the pot in the solar panel cooker, stick it out in the sun and two hours later you have lu...

CooKit Solar Cooker Made Out of Wood

The nice folks at Solar Cookers International gave us permission to reprint plans for their CooKit solar cooker in our book Making It. You can access those plans, as well as many other solar cooker projects, for free, on their website here. I’ve made CooKits out of cardboard and aluminum foil a couple of times. One problem is that I eventually bang up the cardboard and I’ve got to make a new one. This summer I had a lot of  1/4 inc...

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

...derwear 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 called Union House which carries a functional, if unexciting line of apparel. Unless hipsters take to golf shirts in an ironic fashion judo move, these offerings will never be cool like the domestically m...
