I ran out to Sheeps and Peeps Farm this AM to take some video with the digital camera. The Bergey Excel-S turbine was jammin! Some video highlights include Sampson (the dog) howling (he sounds like an owl), wind chimes, the turbine pegging its nameplate rating (10kW), and the utility meter "spinning" backward.
One note about the spinning backward; the new digital meters have a set of bars that emulate the pace and direction of electrons through the meter. These dial emulators are hard to see and are not nearly as exciting as the traditional dial-style meters.
