Been waiting for this for a few years. I remember seeing a blurb on them quite a few years ago, it's cool that there are companies starting to commercialize it.

Yeah, they only have 9% to 10% conversion rate, but that really doesn't matter. You're taking a window that normally does absolutely nothing, then having it produce energy!

You could get quite a bit of energy out of office buildings and tall high-rises. Lots of windows on those things.

But how much does it cost? Regardless of how energy-efficient it might be, it could take quite a while to be cost-efficient.
