Using the suns 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.

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.

(20,729 posts)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.

(53,661 posts)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.

(53,661 posts)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.

(10,618 posts)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.

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

(14,881 posts)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.

(16,926 posts)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.
