Energy Ball® Wind Turbines
Energy Ball is a wind turbine that generate electricity at very low speeds. Read on for more about this Netherlands based company.
" ... low-noise turbine ... six curved rotor blades which are attached to the rotor hub with both ends ... the wind blows parallel to the rotor hub through the rotor. ..." 
"... creates a wind flow pattern that converges ... then accelerated through the rotor, resembling the rapids in a river ...translates into a higher aerodynamic efficiency compared to conventional wind turbine designs. "
" ... producing electric energy as from very low wind speeds and has therefore a very low standstill time. ..."
