Alternitive energy source: Dyson-Harrop satellite

So I read this rudimentary stub om wikipedia about a theoretical satalite that would use a electrified wire to pull electrons from solar wind. From there the elctrons would be used to create electricity to power an infared laser that would transfer the remaining particles downto earth. On earth the electrons would be used to create electricity that we could use to power most things on earth.

According to the theory, as the satellite growsnin size, sodoes the amount of electrons accumulated and by extension, the amount of electricity produced. One theory suggested that this design could produce between 10x and 100x the amount ofenergy currently used onthe planet, anda small one could be used to power almost 1000 homes.

And yet we never hear about this idea. This should be implamented imediately. It is a completely safe, free, and efficient way of producing electricity in large quantitys, with none of the draw backs of wind, solar, geothermal, coal, or nuclear methods accept for the size factor. So long as the satellite panels face the sun, they never have to be turned off because it is 1. Self sustaining, and 2. The sun isalmost always pumping out solarwind.

I also heard a theory to put one of these satelites in the Van-Allan belt, which is just a large accumulation of the nessacery particles

    Jan 13 2014: Very interesting article, Justin. Here's the link, for the benefit of later readers.


    I wonder how well this idea will fare against other forms of space-based power generation.

    • Jan 22 2014: Thank you for posting that link. You know I think it would do fairly well. The general idea is sound and the sun is almost always letting off solar wind. The biggest problem would be transmition back to earth. As stated in other comments, a laser can make it through the atmosphere, but if it runs into clouds or fog, it can get distorted.

      Any sugestions?

        Jan 23 2014: Most discussions of space-based solar power use microwaves rather than lasers to transmit back to the ground. The receiving station would be a pattern of dishes several hundred feet wide, and to my understanding, such a large mi9crowave beam would not be significantly bothered by weather patterns.
