The future of wind energy harvesting. The Flettner-Enebird is about 10 x as effective as wind turbines.

The startup is to develop the prototype and later license production partners. The rise in efficiency is so huge that the "old tech" will perish as fast as the wind energy companies will be able to produce the Flettner-Enebird to replace them.

To decide whether or not to invest, check the technology and it's implications.
