    Default News on the alternative energy front

    This is NOT intended to turn into a political issue. Just wanted you guys to see this article. I can't vouch for it's value, but it's interesting at the least, and maybe great news. Let me know what you think.

    I will wait to see how it develops, but the one thing I did see was the cost was 1/8 that of panels, but will be replaced every year. How often are the panels replaced? I don't think every 8 years.

    Great point. I didn't think of that. I believe the usual life span of a panel is about 20 years. Hmmm. They mention that the balloons "may" last for up to 5 years, but are routinely to be changed out yearly.

    The article mentions how inexpensive the materials are to build them. I wonder what the manufacturing cost is comparatively. That may be the real story.

    Thumbs Up

    Thanks for the article.............

    CPV's are the only way to get serious power. But if
    this cheap set up delivers then WOW!! Most any
    homeowner could justify one.

    ".....[SIZE=2]That's why the company anticipates replacing systems every year even though the balloons can last 5 years,"

    The part they are talking about replacing is the cheap
    "balloon" reflector part. The hardware/photovoltaic cell
    would not be.

    Sounds really fantastic.

    You're welcome. I'll be interested to see if there is a private home use application for them. The article implies that they would be used in large "power plant" configurations to supply power on a large scale. Is that viable?

    Certainly.......... The reflectors on CPV's are the spendy
    part. Especially large ones. Using the balloon configuration
    even large ones become inexpensive and viable.

    I would imagine that the balloons being replaced would be
    recycled into new/refreshed balloons.

    Oh, thanks Sundance. Let me know if you learn anything else interesting about them. There's probably more info out there that I am not aware of. I just thought it may be of interest to several people here.
