Vertical axis wind turbines
Vertical axis wind turbines are a growing segment of the wind turbine
industry; they are designed to work quietly and efficiently in urban
environments where the wind direction changes frequently. They solve
problems that plague small wind applications in urban settings including,
aesthetic concerns, space requirements and sound levels.
- Can produce up to 50% more electricity per year than conventional
turbines with the same swept area;
- Generate electricity at much lower wind speeds, as low as 4 mph
(1.5 m/s)Will continue to generate power in high wind speeds, up to
130 mph (60m/s) depending on the mode;
- Direct-drive units with no gearbox means a more efficient transfer
of energy and no leaking oil;
- Will not harm wildlife, in terms of bird and bat strikes.
