Perhaps Dave and Barnz, your panel's seismic activity could be harnessed as a form of renewable energy. I can see it now, the SIPSPGS, the SIP Seismic Power Generation System! The system could also be extended to harness the power released as green timber checks. It's going to be the hottest thing since the tiny house!
