[Greenbuilding] [BULK] Re: solar payback

[Lawrence Lile]

Nanosolar isn't vaporware, they just have their first year's production
already allocated.  You'll see the rest of the players slowly creep down
in price, but I don't expect us mere mortals to be buying solar cells
that cheap anytime soon.  

My buddy who keeps an eye on these things says he saw new solar cells on
Ebay for $2.50 a peak watt the other day.  They were a Chinese
manufacturer that he'd never heard of.

As someone who has been solar curious for a few years now, I am
wondering if
anyone has any solid specs on
Nanosolar's<http://www.nanosolar.com/index.html>new technology and if
so, will it really make a difference for those of us
on the periphery?  I want to put solar up, but have not been enamored
with
the cost or efficiency of current technology.  So far I have envelope
efficiency, and energy efficiency and am still working on lifestyle
efficiency (two out of three ain't bad), so I feel that if solar
technology
can meet me half way by coming down in price and being more efficient,
I'd
be glad to use it.

Is Nanosolar just more vaporware with loads of VC money?
