I didn't know this system existed until I recently traveled in the states. I found the entire concept absurd. I though t at first it was a joke, a play on how ridiculous security practices were, but then I slowly realized that the voice on the intercom was serious about "code orange". Also, in airports, if you just sit near the first class lounge, you can get free wifi.

Congrats to team Germany. I'm part of team Ontario-BC (we got 4th) It was a great experience, but there were problems for the contests. Team Germany even lost power for a while from the grid. And yeah, they did kinda just pile the PV panels on their house, they didn't even have a solar thermal system. I hope next year they put a limit on PV size, because it became partly a competition on who could put the most panels up for the net metering part.
