The truth about cellphones

Rechargeable batteries with solar cells

Now here's a great idea: integrate a solar cell directly into a rechargeable battery so that it can recharge just by facing the sun.


The SunCat batteries were born when its creator wondered as to why "hasn't anyone made a battery with integrated solar cells" and answered: "The batteries should just bask in the sun like a cat and left for a while, in a sunny window, they would slowly recharge."

I think it's a great idea and the good part is that you can do it yourself... that is, if you can get around the necessary parts and have the skill to build them :-)

Just check the SunCat blog post for details, here.
