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.
Groundbreaking began Wednesday on the Oliver Wind Energy Center, which will soon have 22 wind turbines generating 50.6 megawatts of electricity, enough to power 16,000 homes. The project is a joint venture between FPLEnergy, the national leader in wind energy, and Minnesota Power, which is purchasing the electricity.
