Gallery: Solar Winds Could Provide 100 Billion Times Earth’s Energy Nee...


Researchers from Washington State University have published a paper in the International Journal of Astrobiology stating that energy from solar winds could replace conventional forms of renewable energy produced on Earth such as solar, wind and biofuel power. In the article, the scientists theorize that a giant solar sail, designed to harness solar winds, could generate 1 billion gigawatts of electricity.

    I think its a great “idea” – but it might more pratical to use Earth energy for us and space energy for satellites…

    Just a few homes and small businesses using solar and wind energy in every city would help cut back on the energy crisis. With nuclear power plants as back up only…

    The 100 billion assumes the sun is completely surrounded by the satellites. The 1 Billion GigaWatts is from 1 satellite, though even that is far more than we use.

    Does that mean the whole earth uses just 10 megawatts of electricty? Just a few large windmills?

    Instead of going into space, why not let space do the work, as Tesla proposed, with his wireless transmission of power,over a hundred years ago. i.e. Wardenclyffe or his 1930 Pierce-Arrow electric car, powered by his mysterious black box.

    While the “renewable” component of this idea are to be lauded, there are several problems with this idea.
    1) What about all those meteorites, small, medium, and large that it would inevitably encounter? How easy would it be to detect and patch a hole in the tarp?
    2) This would have a huge up-front capital cost. Not something our planet is going to be able to dish out any time soon, given that we are in barely-eeking-by mode.
    3) The health effects on humans, animals, plants from the transmission of this power are not well enough understood or accounted for. Society is in denial about the harmful effects of our existing gadgets.
    4) This would reinforce the need for a distribution grid. I’d like to see renewables move us toward grid independence, not the other way around.

    I call it a cute idea that should not be pursued for 100 years until we are more mature and able to deal with these things with integrity; and by then, we are likely to have found other free energy sources that are cheaper, and much easier to implement.

    …and who would control that power and to what end?

    ERm, yes, “powerful infrared laser beams”, in orbit?!

    Does anybody see a problem with that?!

    Single-walled carbon nanotubes could provide a way to build a space elevator into orbit, giving cheap space travel and a way to transport that energy safely back down to earth. Powerful beaming devices are NOT a safe way to get that energy down from orbit.

    So, if it produces a hundred billion times more than the earth needs at 8400km wide, erm, why not make it smaller?

    Just saying.

    I think the concept of transmitting this energy to earth will result in a very high loss due to resistance, in whatever form is developed to eventually handle this. However what about space travel? Do these systems create enough instantaneous power to support space travel or are the better for long term low capture applications?
