The part about the solar goes from the 3 to 4 minute points. There's also a nice little bonus part at the 4:30 to 5min sections. If you want to watch the entire video it's very neat. The best part is that the entire structure floats and can be moved wherever it needs to go. But there's lots of solar and off grid goodness with this one. Even their boat has solar.
