Printing presses running solar electric film?

Dear Nanosolar friend:

We wanted to let you know of a major milestone in solar energy technology we have now achieved: The solar industry's first 1GW production tool.

Yes, that's 1GW of capacity from a single production tool!

You can see it yourself in action in a video we have decided to release and share with you.

Most production tools in the solar industry tend to have 10-30MW in annual production capacity. So how is it possible to have a single tool with Gigawatt throughput?

This feat is fundamentally enabled through the proprietary nanoparticle ink we have invested so many years developing. It allows us to deliver efficient solar cells (presently up to more than 14%) that are simply printed.

Printing is a simple, fast, and robust coating process that in particular eliminates the need for expensive high-vacuum chambers as traditionally used to deposit thin films.
Our 1GW CIGS coater cost $1.65 million. At the 100 feet-per-minute speed shown in the video, that's an astonishing two orders of magnitude more capital efficient than a high-vacuum process: a twenty times slower high-vacuum tool would have cost about ten times as much per tool.

There's still a lot of hard work to be done for us to bring solar power everywhere. But at this time we wanted to share with you our excitement about transformational progress happening.

Thank you for your continued support of Nanosolar. While deployment of our product will focus over the next 12 months on installations with our wholesale customers (which includes the world's largest utility), we are looking forward to making our products more broadly available to everyone in 2009.

From Nanosolar's blog:

Please note: That's the price for one. Printing Press #2 would cost about a third less because all they have to do is follow the blueprints from unit #1. As you build more the process becomes more streamlined and efficient. The difference in cost to build the first Model T and the last was something like 200 to 1.
