Windhunter is a project for hydrogen mass production based on electrolysis of the sea water. It consists of a platform that sustains some wind mills. They produce electricity following that electricity produces hydrogen and oxygen through the well-known electrolysis process. The wind turbines have a power of 2 MegaWatt. From the experiments presented in the “hydrogen power” category on cars-and-trees.com, it is required only a small amount of current (abt 10Amps) to make enough hydrogen to run a car. Imagine the possibilities of 2MW power in continuous run. Anyway, some calculations have to be made, but it’s obvious it can generate in time great quantities of energy. For free.
The platform can be put in the sea or oceans and doesn’t interfere with any human eyesight (except maybe ships travelling across the sea).
The bad part is that its construction is not cheap at all.
