1 Executive Summary

WindWays has been established to develop and market 6 related products driven by wind turbines up to 4,000 kW, using the energy of the wind to:

1 aerate sewage or waste water or reduce it
2 make biodiesel from algae grown in the ballast tanks
3 generate fresh water from salt water, or dirty water
4 provide heating, for example in lighthouses & greenhouses in the north.
5 Make electricity
6 Pump water or oil.
- or combinations of these, all of which will reap carbon credits by replacing the use of electricity or fuel.

Investors and or Joint Venture partners sought - worldwide
