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...

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...

Sundiner

...irrors is an oven enclosure. Plastic foam insulation and a pair of glass plates prevent excessive heat loss. The solar energy grill works in this simple way: point the mirrors toward the sun for a few minutes until the right temperature is reached (built-in heat indicator dial) and pop a tray of food into the oven. There is no fire or fuel to handle. Sole source of cooking stems from the collected, concentrated rays of the sun. Here is a sample o...

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...

Another Panel Solar Cooker

Poyourow demoing her solar cooker design There’s no one size fits all solution when it comes to the world of solar panel cookers. All have their advantages and disadvantages. I got an email from author Joanne Poyourow, leader of the amazing Los Angeles Environmental Change Makers, with a simple and effective design she came up with. Pouyourow’s cooker comes together much faster than the CooKit design that I blogged about earlier th...

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...
