Cooking with the sun

Using the sun’s abundant power could be the solution for people who cannot afford escalating electricity costs. Channelled through simple, curved dishes its’ rays can cook food and boil water.

Neat - wonder how much they are. Would like one.

We used it for starting camp fires in the Boy Scouts.

Google "solar cooker" to see designs going back in the the last century and before, including plans for one you can make with cardboard and aluminum foil.

contrary to what seems to be western popular opinion, African/third-world women aren't universally in danger of rape everytime they wander from their hovel in the bush.

Nor do most of them even live in the bush. 72% of the population of sub-saharan africa lives in urban slums.

africans is more like 40-50% (e.g. 57% in south africa, 47% in liberia, nigeria, egypt, 12% in uganda, etc.).

That takes a bit longer but will heat water for washing and bathing, distill water, cook roasts, vegetables, eggs, beans and dehydrate food. There's a world of information out there.

Plus passive methods for heating homes and turbine generators. The solutions are as simple as cardboard and foil to using those controlled by computer chips. It's a shame people have been in hock to the power companies all this time.

Guess they're trying to kill off the people in the third world with these contrivances. That's not very nice.

No one is suggesting you give up being in hock to utility companies, though. Most of us are. No one's being attacked by these, so be careful with your cooking.

As long at it keeps the pot of stew above 68 °C (154 °F) there's no problem. A decent solar cooker has no trouble getting that hot.

The reason people aren't using them has to do with laziness. You have to go outside to use it, and when the sun is out people stay in their air conditioned spaces. And on a cloudy day, they don't work. That's a pain, and people can't be bothered by anything inconvenient.

as if it were A) entirely new and B) totally going to solve all the third worlds problems.

It's a cool idea and has some utility but it has been way overhyped.

I'm more interested in how these humidity-harvesting windmill are going to work out: http://niceartlife.com/?p=2985

Clean water is a bigger concern in the third world than heating sources.

/besides, everyone knows rocket stoves solved all the third-worlds cooking problems. http://en.wikipedia.org/wiki/Rocket_stove

They're also sold pre-assembled by several companies in the US.

They're both shaped the same way. That would be an excellent idea to put old DirecTV dishes to good use.

I've been solar cooking for 2 years now. I got that one last year and I LOVE it.

For those who are mocking it, it cut my propane bill dramatically. Paid for itself probably in one summer, with me only having a day or two each week to cook, and for only half the summer.

I can cook outside pretty much from March to October on sunny days. I'm pretty far north, so the sun gets too low for the rest of the year to generate enough heat.

And I LOVE the way food comes out. Meat cooks until it falls off the bone, but tender and very flavorful.

and will likely cook up some split pea or black bean soup tomorrow. If you live in an area with even moderate sunshine, you owe it to yourself to try solar cooking.

When cooking can be deadly

Dar es Salaam, Tanzania (CNN) -- An estimated 3 billion people -- nearly half the world's population -- still use an open fire as their primary source of energy for cooking and heating.

But there's a problem: the smoke.

"You have respiratory issues, lung disease, you've got pneumonia, and you've got longer-term issues like cancer and heart disease as well that can result from exposure to indoor air pollution," said Radha Muthiah, executive director of the Global Alliance for Clean Cookstoves.

The World Health Organization says this type of pollution causes nearly 2 million premature deaths each year. That's more than tuberculosis and three times as many as malaria.

more -> http://edition.cnn.com/2012/02/07/world/africa/tanzania-stoves/index.html


and,

Solar cooking is the simplest, safest, most convenient way to cook food without consuming fuels or heating up the kitchen. Many people choose to solar cook for these reasons. But for hundreds of millions of people around the world who cook over fires fueled by wood or dung, and who walk for miles to collect wood or spend much of their meager incomes on fuel, solar cooking is more than a women carrying wood choice — it is a blessing. For millions of people who lack access to safe drinking water and become sick or die each year from preventable waterborne illnesses, solar water pasteurization is a life-saving skill. There are numerous reasons to cook the natural way — with the sun.
