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.
Offshore wind is considerably more expensive, with costs of between USD 0.10 and USD 0.21/kWh. The regional weighted average installed costs for onshore wind range from around USD 1 280/kW to USD 2 290/kW.China and India have weighted average installed costs 35% to 44% lower than in other regions.he cost of electricity from wind is falling. This is due to total installed costs declining in line with lower wind turbine prices since 2009 and, at the same, technology improvements mean more wind is harvested from the same site with new wind turbine technologies.
