The timing may be calculated but that's about it. If a product isn't going to work out, that's one thing, but Musk doesn't waste time on vaporware. Notice that Tesla never put a silly will-never-be-an-actual-product car for display at auto shows.

But he does take sign ups to colonize Mars, talk about being able to do the hyperloop for $1B, etc.

> Rumor mill has it that SC has been struggling

It wasn't a rumor. Solar City was publicly traded and the struggles were documented.

It sounded like this was condensedware/liquidware (what's the opposite of vaporware?), namely that the event had actual houses with actual manufactured, installed solar roofs in the form of traditional roofs. Presumably there were at least four of them, the four tiles pictured. There is a picture of what appears to be an actual house, presumably with a solar roof.

Hardware should do.

musk may be talking a lot but he's also delivering a lot. look at all the commercial space flight companies out there crushing it. ez.
