All you need is a “smart meter” that allows Google to tap into your energy usage and they’ll tell you where you can save money based on consumption.
I have to give it to Google…they sure do have some smart people that come up with unique ideas. Go read more about PowerMeter over at their .org site.
Next on the invention table? Keyboards for your computer that read your fingerprints so online billing information is no longer needed. You go to a shopping cart and they know who you are already. The project will then turn into small electrical currents that are sent through the keys into the human body where they can read your brain and index your entire life.
