Micro power revolution set to blow in

Micro-turbine inventor Lucien Gambarota said Thursday the new compact designs, with a rotor diameter of 25 centimeters, were more effective than conventional wind turbines with a rotor diameter of 50 meters, such as Hong Kong Electric’s monolith wind turbine on Lamma Island.

The miniature windmills will allow users from all sectors to reduce energy costs while reducing carbon emissions from mainstream power use.

The cost of the new mini-turbines will only be 10 to 20 percent of conventional windmills and could be recouped within two years, according to HKU.
