Bladeless wind power generator produces 200% more energy at almost half the price.
“…Instead of spinning blades, the wind is being harnessed by a curved sail-shaped body which follows a back and forth 3D knot motion. This motion (like a wobbling dish) allows the conversion of the majority of the wind kinetic energy into mechanical energy through the use of pistons. The pistons are connected to a hydraulic system which enables the conversion of the mechanical energy into hydraulic pressure and then, to electricity. ..” via: http://www.saphonenergy.com
