KiteGen STEM

A 3 MW KiteGen generator

In the “Stem” configuration the wing pull the cables that, through a pulley system, activate the alternators on ground, which in turn produce electricity. When cables are entirely unwound, the wing is guided to a position where it looses its wind resistance and the cables are wound in. Energy consumption of the winding phase is a minor fraction of the energy generated during the unwinding phase.

At the very core of the project is the software that autonomously pilots the power kites, so that the flight patterns can be controlled and normally directed to maximise the production of energy.

In 2006 KiteGen Research has built a first prototype, codenamed KSU1, tested at an altitude of 800m with the authorization of ENAC and ENAV (Italian Civil Aviation Authorities).

Beyond the verification of the theoretical data, the KSU has produced energy, thanks to the unwind/rewind cycle: 5kW average and 40kW peak, with a ground of 4.5 m/s.

The first operative Stem is located in Sommariva Perno (CN), its construction started in 2010 while now (Feb 2012) it is completed in all its components and it is under testing and optimization phase.

The following video shows how the Stem generator works:
