Patent ID: 7210896

Claim:
An electrical power generation assembly comprising a main body comprising two or more portions wherein a first portion is arranged to define the frontal region of the main body and a second portion is arranged to define the remainder of the main body and said main body having a sufficiently low density to effect lift thereto, wind driven means on a surface of said main body to generate electrical power, said main body having a frontal region including a part-circular cross-section or a part-elliptical cross-section, the main body having a first distance perpendicularly from a central plane of the main body to a line of intersection between the frontal region and the remainder of the main body, the main body having a second distance from the line of intersection between the frontal region and the remainder of the main body parallel to the central plane of the main body to a line of intersection between the most upstream points of the frontal region and the central plane of the main body, the ratio of the first distance to the second distance being equal to or more than 0.5 and equal to or less than 5, the wind driven means having a diameter and the ratio of the diameter of the wind driven means to the first distance being equal to or less than 0.25 wherein said first portion of said main body contains a lighter than air fluid and said second portion of said main body contains air.
