Save on Energy: Your vacuum cleaner may have a hard-floor feature, but you’ll save on electricity by sweeping your linoleum, tile and hardwood instead. A solar cooker eliminates the need for an open flame, meaning cleaner air. At its most basic, the box cooker consists of an open-topped box that’s black on the inside, and a piece of glass or transparent plastic that sits on top. Dark colors are better at absorbing heat, that’s why the inside is black. ­To cook, you leave this box in the sun with a pot of food inside, the pot sitting on top of the black bottom of the box. A pot of food sits on an arm that holds it in the center of the curved reflectors, suspended slightly above the bottom point of the oven, where all the light is concentrated. A panel cooker, which uses parabolic reflectors positioned above a box-type oven, tends to be smaller and lighter. This interaction is similar to the concept that makes one form of solar cooker, the box cooker, generate high temperatures from sunlight.

But the humps are actually high in fat, which the camel burns when caloric intake is too low. It takes a lot of wood to cook meals for an entire family every day, and what few wood sources there are continue to dwindle. Solar cookers, which can cost as little as $10 a unit for a simple design, easily reach the upper temperatures of pasteurization, and they cook a meal in a few hours, depending on the cooker and the type of food. While solar cookers are a great solution for many developing countries, there are a few drawbacks. The users who are interested in the purchase of the appliance can also find comfort in the fact that this appliance does not have any chemical solution in the usage.

If you have these problems, you may not be sure who to call. This smoke, filled with particulates, is bad for the environment, but it’s even worse for the people who are breathing that air. When people use open fires to cook indoors, they end up inhaling microparticles that can cause all sorts of health problems, including both lung and heart disease. That’s hot enough to safely cook meat. A parabolic cooker can get even hotter, up to 400 degrees F (204 degrees C), which is hot enough to fry food or bake bread. The box cooker is a simple type of solar cooker. The cooking pot goes in a plastic bag while it cooks, which acts as a heat trap (like the transparent top on a box cooker). The problem is that in many poor, rural areas in places like Africa and India, trees are scarce. Perhaps the bigger problem is that even in places like India, the sun isn’t always shining. While we were impressed with this cleaner, it felt like a budget buy at times. You can buy a wide variety of solar cookers online at lots of “green” consumer sites. Families have to walk for hours to collect cooking wood, and they end up spending what little money they have on their fuel, leaving less money to buy food.

The more central applications have to do poverty, hunger and disease. For more information on solar cooking and related topics, look over the links on the next page. Solar cooking on a broad scale is really only viable for countries that have a dry, sunny climate for at least half the year. The electromagnetic rays emitted by the sun have a lot of energy in them. It doesn’t take a whole lot of heat to pasteurize. At maybe 3 to 5 feet (1 to 1.5 meters) across, it’s essentially a sun-powered oven — an enclosed box that heats up and seals in that heat. While smaller than the green anaconda, yellow anacondas still reach considerable sizes, typically measuring between 5 and 9 feet (1.5 and 2.7 meters) in length. That means firewood is still a necessity for the sun’s off hours. But if you’re still looking for that silver bullet for your car’s gas tank, you can try your luck on the next page. If the soap-and-water mixture doesn’t lift the dried paint, try scraping. Use baking soda for a quick, moisture-free refresh, white vinegar for removing odors like pet urine, and commercial wool wash detergents for cleaning.
