SPACE BASED SOLAR FARMS POWER UP


This would solve our energy needs overnight. but with the huge technological and financial challenges, can-space base solar power ever take off?


ex-NASA scientist seeks visionary billionaire to help change the world, high risk venture. return not guaranteed.
John Mankins, the scientist in question, has not yet reached the point of placing a classified ad, but it could soon be an option. The 25-year veteran of the US space agency is the man behind a project called SPS-Alpha, which aims to loft tens of thousands of lightweight, inflatable modules into space. Once there, they will be assembled into a huge bell-shaped structure that will use mirrors to concentrate energy from the sun onto solar panels. The collected energy would then be beamed down to ground stations on Earth using microwaves, providing unlimited, clean energy and overnight reducing our reliance on polluting fossil fuels. The snag? It is unproven technology and he estimates it will take at least $15bn- $20bn to get his project off the ground.

    Hi there just wanted to give you a quick heads up. The text in your article seem to
    be running off the screen in Opera. I'm not sure if this is a formatting issue or something to do with browser compatibility but I figured I'd
    post to let you know. The layout look great though!
    Hope you get the problem fixed soon. Thanks

    I've been surfing online more than three hours today, yet I never found any interesting article like yours. It is pretty worth enough for me. Personally, if all web owners and bloggers made good content as you did, the web will be much more useful than ever before.

    Hiya! Quick question that's entirely off topic. Do you know how to make your site mobile friendly? My blog looks weird when browsing from my iphone 4. I'm trying to find a theme or plugin
    that might be able to resolve this problem. If you have any suggestions,
    please share. Cheers!

    Superb blog! Do you have any hints for aspiring writers?
    I'm hoping to start my own website soon but I'm a little lost
    on everything. Would you suggest starting with
    a free platform like Wordpress or go for a paid option?
    There are so many choices out there that I'm totally overwhelmed ..
    Any tips? Thanks!
