A Parvati Solar Cooker

...time is much longer than it would take on a conventional stove, but with a solar cooker there is no danger of burning, making the process, in our opinion, easier than stove-top cooking.

Just remember the oven mitts–this thing gets hot! When the sun gets higher in the sky, as we move into su...

The Sundiner–A Groovy 1960s Era Solar Cooker

...ce age insulation material. Grilling is really not the best application of solar energy–you lose the smoky flavor and grill marks you get with fire–which is probably why the Sundiner never caught on. More recent solar box ovens that I’ve seen, both commercial and homebrew, have shelves with adjustable angles, making it easier to use them as crock pots. Nevertheless, I admire the efficiency of the design–the legs also double as a handle and the pan...

What’s the Best Solar Food Dryer?

...oisson indirect dryer. In an article in Permaculture Activist, “Evaluating Solar Food Dryers: Stocking Up with Solar Power,” Scanlin says, The Appalachian indirect dryer produced higher temperatures than the other two dryers and also removed more moisture from the tomatoes drying inside each day. In one test, the Appalachian dryer removed 32 oz. (0.95 L) of water during ta day, while the Brace direct dryer removed only 20 oz/ (0.59 L), and the Poi...

DIY Solar Space Heating

...thern 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! If you live in a place that’s both co...
