Re: Building Portal (not about portals)

Also, portals work on surfaces that were not intended to take them. (More noticable in Portal 1). I think they just respond to silica in light-colored concrete. And also moon rocks, which were an unnecessarily expensive way to make a good portal gel. I *think* that the air tubes can be accomplished ...

Re: Nitroglycerine, 163X

From what I remember there were lots of small ceramic bowls of acid, into which glycerine was dropped, and then the excess acid would be washed away.

Continuous 1-g acceleration is incredibly difficult. I think you can go anywhere in the solar system in three weeks though. However, you can do almost as well with much, much less impulse (use the same insanely powerful torch, but no tanks.)
