I wrote a post about induction lamp technology a few days ago – a company called Everlast is producing a solar and wind powered induction lamp street light. PV panels, a turbine, and a 70-100W fluorescent induction source. The system as a whole is pretty sweet – the wind turbine operates at as low as 2-3 mph, and has an electric shutdown after 60 mph. I would assume that those blades could create some catastrophic failure on high winds, as any wind power collector.
Check out Everlast’s product page on the PVW Solar/Wind Street Light. It’s pretty interesting!
