Wattson
Looking for an easy way to cut your electric bill? Stop using so much power. It sounds easy enough, but sometimes you need someone to tell you when you're being wasteful. That's what Wattson does. Just plug this device into your fuse box and it will monitor your electric use. When you're using too much electricity, it glows an angry red color to let you know you might want to cool it. When you're being less wasteful it glows a calming blue. It might take a while to make back the $250 you'll spend on a Wattson, but how can you put a price on piece of mind?
