How long were the Beatles famous?

Answer 1

Beatlemania started on October 13, 1963.

They first became popular in Germany, but I believe Beatlemania was an Americanism dating back to 1964 when they came to the states and appeared on the Ed Sullivan show on TV.

Answer 2

Wind energy (using wind tunbries) requires a fairly strong prevailing wind to be cost effective. The units can be set up off shore if the wind is strong and predictable. The larger the diameter of the fan blades and the higher up they are the more energy can be taken from the wind. Individual blades may be almost as long as a football field. Other sources of energy must be used when the wind is not blowing. Farmers are renting out the edges of their fields to power companies for wind tunbries and other tunbries are located in large wind farms.

Answer 3

From 1963 until the present day.
