29 May, 2002 – Japan’s Ishikawajima-Harima Heavy Industries Co. [IHI] is reported to have built equipment which is able to stabilise wind power generator output regardless of wind availability.

This development contrasts with wind generators which rely upon fluctuations in the amount of wind available to produce power.

The company’s new equipment, which consists of a high-speed iron flywheel and an induction generator, eliminates output fluctuation. When the wind is at low levels, the kinetic energy of the flywheel powers the induction unit as a generator, releasing stored electricity.
