Small Wind Turbine

Description
The is a power source, that can be placed on a Module, Vehicle, or the Players backpack. The wind vane will only produce power while in windy weather.

Although smaller than the Wind Turbine, the wind vane can be used on the side slots of the backpack (it can be put on the other slots but it won't produce there).

Production
A wind vane produce 0.5 units/sec, or 8 secs/column worth of energy (same as the solar).

It means that without any other source of energy (other than the backpack's default regeneration), a single wind vane will fill a backpack main battery in about 12 seconds (it would be 20 seconds without the backpack's regeneration).

When placed on Modules, a wind vane will fill one column of battery in 8 seconds. So for instance, the 8-columns battery of a  Research station will be filled by one wind vane in 64 seconds.

Crafting
The can be crafted in the player's backpack, using 1 piece of Aluminium.
