After Hurricane Sandy, I became slightly obsessed with alternative power, but focused most of my energy on generators, always remembering that I can only store so much gas. The natural alternative to engines and gasoline is solar power, but I wasn’t sure I was looking for a whole-house solution since we don’t have room for batteries and I’m not a fan of selling my surplus energy back to the power company. An idea for a portable solar solution rattled around in my head for years, and while studying for my Amateur Radio Extra Class license exam (K2GAD/AE!), plans started to germinate that resulted in what you see here.

It is mostly self-contained, is completely portable, will charge laptops and phones, run a ham radio station, or just light up a room. It will even float!
