Hay Boxes or Fireless Cookers

Illustration from The Fireless Cook Book Mrs. Homegrown here: Jessica from Holland sent us a letter recently praising our work, but very, very gently scolding us not including the hay box, a groovy old energy saving technology, in our book. We do stand corrected! And her enthusiasm for hay boxes has reignited our interest, too. We actually considered hay boxes for Making It, but didn’t end up building one for a variety of reasons...

How To Dry Food With the Sun

. But there’s a catch to sun drying: humidity. Food dries best when temperatures are above 85º F and below 60% humidity. If you live in a desert, humidity isn’t a problem. But in most other places in North America it’s simply too moist to set food out under the sun. It will rot before it dries. In Los Angeles, due to the influence of the ocean, it’s slightly too humid most of the year for sun drying to work well. But there...

A Parvati Solar Cooker

Damn, is solar cooking easy! Put some rice in a pot, place the pot in this simple panel cooker, made with cardboard and aluminum foil, stick it out in the sun and two hours later you have lunch. We built our “Parvati” solar cooker with plans designed by Shobha Ravindra Pardeshi that can be found here. Pardeshi, who runs an “appropriate technology” company with her husband in India has another design for a similar dish-sha...

Solar Light Hack

We wanted a solar powered light over our new entrance arbor. The problem is that most of the lights available are just plain ugly. And the solar panels on the cheaper models are usually mounted on the light itself making it impossible to place them in a shady spot. I came up with a simple solution. First, I bought an inexpensive solar light intended to be mounted on a fence. I took it apart and desoldered the LEDs off the circuit board. Nex...

Remember to Label Those Jars!

e no idea. They were probably the result of some late night canning frenzy two years ago. At the time I probably thought to myself, “I’ll label them in the morning.” Not only should the jars be labeled, but it would also have been nice to have some notes on the recipe I used and where the fruit was sourced from. To this end I’ve started a preservation diary in a useful program called Evernote. Perhaps I should get a tatto...

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...

DIY Outdoor Shower

y will you be saving water and burning less fossil fuels to heat that water, but your body odor will soon separate your real friends from superficial hangers-on. But we urban homesteaders don’t need to be stinky since it’s possible and easy to build an outdoor solar shower. There are two reasons this makes sense, particularly in a place with as warm a climate as LA. First of all, you can direct the water straight into the garden and...

What’s the Best Solar Food Dryer?

Appalachian Food Dryer. Image: Mother Earth News. Dehydration is a great way to put up food. Second to freezing, it’s the best way to persevere nutrition without adding sugar or salt. And if you use the power of the sun, you won’t need to spend any money on electricity. In a desert climate you can just put your food out on screened trays. But just a bit of humidity in the air makes this approach risky. Food can spoil before enough mo...

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...
