A Taiwanese company called Hi Energy Technology has brought onto market a new design of a vertical wind turbine that they intend to sell for home use.
Vertical wind turbines proved to be more efficient and advantageous in comparison with the horizontal ones as they are more cheaper, smaller in size making them easier to mount at ground level, portable and also safe for the birds. Hi Energy Technology provides their wind turbines with the main rotor shaft running vertically in 50 x 50 x 150 cm packing. The power ranges vary from 400W, to 1500W and 3000W.
Vertical wind turbines can work with winds blowing from every direction, without the need of direction change like horizontal wind turbines work. As well costs with maintenance are lower making the the best solution for home use.
