If you've already got solar panels on your home, good for you. You're part of the solution. But if you don't, you might want to check out the Smartflower Solar System. This plug-and-play system uses two-axis tracking to follow the sun throughout the day, resulting in up to 40% more output than a traditional rooftop system. It unfolds itself automatically in the morning, closes itself up at night (or in high winds), and should you ever need to move, simply unplug it and move it along with the rest of your stuff — something you can't say for most installations.
