Yeah, I did actually. Similar to electric cars or open source it's possible to spot the potential of an idea when it's still in its infancy and not really ready for prime time in every circumstance.

Roofs that generate make a lot of sense and many jurisdictions will mandate some kind of net zero build for new houses. I think there's a lot of room at the top of the market for this kind of product and it will just be standard at some point in the future.

How much of that market Tesla gets and keeps is a harder question, but combining roofing with solar is too obviously sensible to fail I think.
