In other words, a neutron star with a rotation of 1 second will be slowed to 2 seconds in about 30 million years. Thus, the age of a pulsar is determined by its current rotation speed.he idea of a neutron star was developed in 1939 when calculations were made of a star that was composed solely of degenerate neutrons.
The costs for a utility scale wind turbine range from about $1.3 million to $2.2 million per MW of nameplate capacity installed. Most of the commercial-scale turbines installed today are 2 MW in size and cost roughly $3-$4 million installed.ind turbines have significant economies of scale. Smaller farm or residential scale turbines cost less overall, but are more expensive per kilowatt of energy producing capacity. Oftentimes there are tax and other incentives that can dramatically reduce the cost of a wind project.
Wind. FAQs. How tall does a wind tower have to be? Can I put a wind turbine on my rooftop and therefore avoid the cost of a tower? Can my wind turbine affect neighbors surrounding me? How does a wind turbine generate electricity? How much electricity can a small wind turbine generate? Does average wind speed for an area really give enough information for putting up a turbine?
