In doing some research for a completely unrelated (or so I thought) subject, I came across information about solar cookers.
(You can see more information about solar cooking here: http://www.solarcookers.org/index.html )
I know - it doesn't sound too earth-shattering, does it? But after doing more and more research about it, I have found that helping provide women around the world with solar cookers, we can help do so much. They can feed their families without spending so much of their money on fuel costs. They don't need to walk for miles to get firewood. They lead healthier lives because they don't inhale smoke and fumes every day when cooking.
Here in the US, it could help people cut cooking costs, plus help save money on cooling their homes in the summer. Know how hot your house gets when you cook? Not when you have a solar cooker.
I'll post some more soon, but this is something I'm going to be talking about for a long time to come, I can tell.
