Why solar tracking is a key technology for unlocking the potential of utility-scale PV

Quotes for very large solar photovoltaic projects in sunny parts of the United States are coming in at an astounding 5 to 6 cents per kWh. Certainly these projects enjoy economies-of-scale advantages compared to smaller or rooftop photovoltaic projects. There is, however, one other very important technology advantage—because the utility-size systems are ground mounted, trackers

Innovative V-Band Clamp Nut Keeps Turbochargers Sealed

V-Band Clamps encounter many extremes. When it comes to turbochargers, which are increasingly used in light trucks and cars to deliver the power of a V8 engine in a V6, the clamps seal off hot exhaust, forcing compressed air into the intake. The result is lighter vehicles and better fuel economy. But component temperatures around
