With this machine, the idea is to harness as much possible energy from as little space as possible.

With the horizontal blade configuration, the turbine doesn't lose energy in the process of resetting each blade to the top of the rotation circuit or in realigning to sudden changes in wind direction.

The mirrors reflect the sun light (If not just to the side which doesn't face the sun) at a higher concentration, allowing for more juice to be gained from each solar panel.
