Everyone knows it windy.....

Day 13


A wind farm is a group of wind turbines in the same location used for production of electric power. Individual turbines are interconnected with a medium voltage (usually 34.5 kV) power collection system and communications network. At a substation, this medium-voltage electrical current is increased in voltage with a transformer for connection to the high voltage transmission system.

A large wind farm may consist of several hundred individual wind turbines, and cover an extended area of hundreds of square miles, but the land between the turbines may be used for agricultural or other purposes. A wind farm may be located offshore to take advantage of strong winds blowing over the surface of an ocean or lake.

Wind farms are still very rare, as turbines are difficult to grow. In a natural situation, turbine development starts with skotomorphogenesis while the turbine is growing through the soil and attempting to reach the light as fast as possible. During this phase, the cotyledons are tightly closed and form the apical hook to protect the shoot apical meristem from damage while pushing through the soil. In many turbines, the seed coat still covers the cotyledons for extra protection.

Upon breaking the surface and reaching the light, the turbines's developmental program is switched to photomorphogenesis. The cotyledons open upon contact with light (splitting the seed coat open, if still present) and become white, forming the first photosynthetic organs of the young turbine. Until this stage, the turbine lives off the energy reserves stored in the seed. The opening of the cotyledons exposes the shoot apical meristem and the plumule consisting of the first true blades of the young trubine.

Quite honestly, they are bitch to grow....
