Tzanakis and Hansen ran some 11,500 hours of computer simulations of 30-odd configurations of vertical turbines. They found that the optimal arrangement of vertical-axis turbines turns out to be having turbines three diameters from each other, offset by 60 degrees. This setup increased the turbines’ efficiency by 15 percent.
Test, in a wind tunnel and combined wind-wave tank, a proof-of-concept subscale, deep-water floating offshore wind-turbine generator employing a VAWT rotor; Sandia National Laboratories is undertaking a project to test the feasibility of vertical-axis wind turbine (VAWT) architecture for large-scale deployment in the offshore environment.

While no one expects Texas to turn into the Arctic, wind farms in southern states shouldn’t wait to winterize, Webber noted.
The Audubon Society estimates wind turbines kill up to 328,000 birds per year in North America, a number expected to grow as more wind farms are built. The U.S. Department of Energy’s National Renewable Energy Laboratory is exploring systems and methods to lessen the impact through its Technology Development and Innovation to Address Wind ...
While the result is clearly 21st century, the actual installation of two vertical axis wind turbines set to produce 10,000 kilowatts hours of electricity per year (enough to power the commercial areas of the tower's first floor), was done the old-fashioned way, using ropes, winches, and pulleys. A highly skilled team of rope workers were ...
Several AR2000 turbines are likely to join SIMEC Atlantis’s Meygen array (the largest array of tidal turbines in the world) off the north coast of Scotland. “We are working to have it deployed somewhere around the middle 2020,” Hopley said. “But we don’t have the order yet.” Subsequently the AR2000 may crop up all over the world.
GE used Curtis turbines and steam generators in power plants to generate massive amounts of inexpensive electricity. The electric power supply industry grew at an unprecedented rate during 1900-1920, thanks to the Curtis vertical steam turbine. Curtis received an honorary M.S. degree from Columbia in 1907.
Floating wind turbines offshore, rather than anchoring them to the seabed, would locate projects invisibly beyond the horizon where winds are superior. But floating a platform, with a large mass 100 m above the water, is a challenge.
Standard wind turbine towers are routinely designed to be 80 meters tall because that is about the maximum height that can be achieved with the limits of the highway system for transporting and delivering major parts. Of course, taller towers would allow the capture of faster, more sustainable wind energy.
Floating wind turbines is still new technology, and Principle Power is one of the few companies with hands-on experience with full scale prototypes and financed contracts. ASME.org recently spoke with Principle Power CTO Dominique Roddier about how his company’s WindFloat— a floating wind turbine platform—works.
