Keep the lights on and the coffee hot. Make sure it's in that thremal caraffe, thingy so it'll still be drinkable when I come back in 8 hours.
And, Darks, see if you can find a bigger fan. Maybe Google "wind tunnel" or something. The two I found earlier are nice, I think, but rather on the small side. We need a REALLY big one. For that matter, the castle project might need a really big one for generation of atmospheric condtions like wind while transiting through space.
Good night.
