How are we going to afford any (additional) photovoltaics?
My dad recently passed on this link to Nanosolar's new solar cell technology - basically conductive ink printed on a metal substrate. I'm sure it's efficiency is crap (though they're not publicly sharing their specs), but efficiency isn't the goal here - the point is they're wicked cheap. So cheap, in fact, they're being touted as "cheaper than coal" per kWh. What? Did I hear that correctly? Cheaper than coal? Where do I sign up? :)
The solar panels we put on the school's greenhouse were predicted to pay for themselves in 50 years. Great. I'll probably have retired by then. Their site doesn't list prices either, so it's hard to verify that any of it is actually true. Otherwise you know I'd be running the calculation myself on this page. heh.
I'd like to dream of super cheap photovoltaics on our roof, but for now I'll have to wait: They're sold out for the next 12 months. :P
