Potential chemical weapons from living organisms. Toxins are effective and specific poisons produced by living organisms. They usually consist of an amino acid chain which can vary in molecular weight between a couple of hundred (peptides) and one hundred thousand (proteins).
1 NREL previously calculated wind farm land usage at about 85 acres per MW of capacity and capacity density of 3.0 Â±1.7 MW/km 2. 2  Yale calculated wind energy usage down to the turbine level, calculating 1-3 acres per turbine.
Larger wind turbines are put on taller pillars, and the wind speed up there is usually somewhat higher. Nevertheless, the power production per unit area of land is not particularly impressive. Wind farms in the US produce power at the average rate of about 1.2 watts per square meter (about 5000 watts per acre).
