How I built an electricity producing Solar Panel Several years ago I bought some remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size.

It took about 4 hours before the thing started work, and was a bit costly (at over 50 dollars) to make. I knew it could be done better and cheaper.
About - Emily Cummins When I was four, my Grandad gave me a hammer and began to teach me how to make toys from scraps of materials found in his garden shed. I loved the fact that we could make something out of seemingly random bits, and my interest in sustainable design was born.
