Feeling vindicated in having gotten rid of my windows comps and gmail. I used to have a dedicated linux box but lately have been preferring the ease of macs. Maybe one day I'll get…

The AC75 class is now going very fast as well with foils, over 50kts. Just recently the 40kt barrier was broken by hydrofoil windsurfers. Fins still have a higher top end but the g…

The upper stage re entering was the craziest thing I've seen live. Can't believe it was burning thru the flap and still had a gentle splash down.

In my brief stint working on spacecraft in the private sector I worked with guys like you that did beautiful things with wiring that I loved to see. I hear you on scheduling too. I…

Nowhere near as extreme but I broke my leg and there was a weird sensation if I touched my leg near the break, my toes would tingle even though they were quite a ways away. Years l…

Nuclear has a large heat source (or can make a large heat source instead of converting to electric first) to do a lot of things like this.

I was hoping there would be something here about using Stirling engines that use decay heat, but looks like they are just using the decay heat itself and not generating electricity…

IIRC that is due to other issues, not aerodynamics. For instance, the engine no longer receiving oil at negative 1 g, or fuel, as the system is designed for gravity flow. Stunt pla…
