The DIY Portable Solar Power Kit. Pretty clever. You need to know how to channel geo-thermal isotopes and downgrade fissionable Deuterium, but hey how hard can it be? Oh all right, just kidding. This is definitely worth a bookmark.
This kit weighs about 2 lbs, costs $180, and will power my Macbook for 1.75 hours (1.83ghz, browsing the web and checking email via Airport Extreme, bluetooth off, screen brightness about 70%) with a little more than 5 hours of good sun…It’s great for emergencies, or just knowing you are powering something real with a completely renewable resource.
