I believe I get the positive intention behind your post, btw - to defend conversation against shallow dismissals - and of course appreciate that. But if you'd please express it in a respectful way in the future, then you'll be contributing to good conversation rather than degrading it further.
No, I actually work in aerospace and know EXACTLY what the fuck I'm speaking of. Do you build satellites? Looking at your history - no you do not. I do. In fact, I'm responsible FOR THE POWER SYSTEMS (that's battery and solar AND any RTG should we ever go that route.)
Sit down.
If you know more than others do, that's great! But please contribute by sharing some of what you know, so the rest of us can learn, rather than putting others down.
