Well, it says in the abstract (and they have further detailed calculations in the paper) that they achieved an average desalination rate of 1.76 kg/m^2/h. So that’s about 1 gallon of water in one hour with 2 m^2 panel. That said, they did their tests using a 9 cm^2 panel, so yields may change significantly on scale up. Not sure if that translates into meaningful cost savings at scale, but it does seem like a significant advance in solar desalination technology. It seems like the paper was focused mostly on salt harvesting, though, rather than desalination. So I expect the real utility to be the combination of the two rather than desalination by itself, if it scales.

Obviously we're in a world where young people do not know how to communicate via messaging systems, online web apps and email. They need to be physically sitting on a file cabinet in my cube while I slam obscure commands into a terminal and swear semi-silently at every typo.

I don't know who writes all this shit, but my experience is that our new hires have less desire to be in an office, in a strange city far from home, than I do.

There were movies but they weren't very good.

From the 1700s, Magic lanterns had moving parts, and there were magic lantern shows.

The Phenakistoscope was a kind of simple movie, and was projected on a stage by the mid 1800s.

The Zoopraxiscope was used with a projector from 1880 in public lectures. It is of interest because it used actual photographs.

The Kinetoscope was a little later, by 1892.

I was just reading this comment on another social site:

"Any statement that starts with "No one would be stupid enough to..." is false."

There's probably too much metal between the cargo hold and the passenger compartment for Bluetooth to work anyway. I think all actual bombs on aircraft (other than the failed shoe bomber) have been triggered by pressure switches at altitude or timers.

So it's not just that they wouldn't be stupid enough, but also that it probably wouldn't be successful even if they were.
