One MegaWatt, Baby!


I looked at my Solar Generation meter and winked. My new Google Glass snapped this picture 116 days ago, on the darkest day of the year, we had our solar panels installed.

It's so powerful to show people that they can retrieve information from the Internet and then manipulate it... Read more »
