Bloody stool is either the sign of hemorrhoids or possibly something more serious like cancer. Bloody stool is a particular one that you want to get checked out if you see that.
Feeder lines usually cost $70,000- $90,000 per mile and operate at a higher voltage (typically 12 kV, 24 kV or 34.5 kV) than what the generator creates, requiring a step-up transformer at the base of each wind turbine. The cost of the transformer ranges from $15,000-$50,000 for each turbine.
The first all-steel windmill and tower was produced by the United States Wind Engine & Pump Co. The first electricity-generating wind turbine was invented in 1888 in Cleveland, Ohio by Charles F. Brush.The turbineâs diameter was 17 meters (50 feet), it had 144 rotor blades made of cedar wood, and it generated about 12 kilowatts (kW) of power.ith current tax credits, wind energy offers American customers the cheapest electrical energy option. At a cost of $35 per Megawatt hours (MWh), wind is cheaper than coal at $37 per MWh and natural gas at $50 per MWh (in 2004 dollars).
