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-$4 million installed.ind turbines have significant economies of scale. Smaller farm or residential scale turbines cost less overall, but are more expensive per kilowatt of energy producing capacity. Oftentimes there are tax and other incentives that can dramatically reduce the cost of a wind project.
Wind Turbines are the most efficient Renewable Energy Power Source, as long as you have enough wind speed in your areaâ¦ While Solar Panelâs price are around 3$ per watts, wind turbines cost around 1.75$ per watts, including the tower.onsidering that the turbine has the potential (depending upon wind quality at the site) to lower your electrical bill by 50% to 90%. Many homeowners may pay power bills of no more than $8 to $15 for about nine months of the year.
