decisions. To that end, wind tunnel aerodynamic tests and aeroacoustic tests have been performed on six airfoils that are candidates for use on small wind turbines. Results are documented in two companion NREL reports: Wind Tunnel Aeroacoustic Tests of Six Airfoils for Use on Small Wind Turbines,

High tunnels with a Gothic peak have long been the gold standard for shedding snow in Northern climates. This is why Johnny’s has developed the Quick Hoops Gothic High Tunnel Bender. In addition to shedding snow, the Gothic-style peak allows for a wider tunnel; 14’ to be exact. Within the tunnel, four 30” beds can be prepared for growing.

The Chesapeake Bay Bridge-Tunnel is the largest bridge and tunnel complex in the world. Recognized as one of the engineering wonders of the world, this facility stretches 17.6 miles from shore to shore and opened to traffic in April of 1964 after 3½ years of construction. “The District used to be operated as a

Existing tunnels are 50 years old. By the time Chesapeake Channel Tunnel is paralleled with Parallel Crossing, Phase II-B, the existing Chesapeake Channel Tunnel will be 75 years old. Oversized escort loads create an average of 338 different lane closures per year in the tunnels, resulting in increased crossing times for customers.
