Hyperloopy things

Ok, bare with me, because it may not sound like but I can actualy do quite a load of random tangley stuff, except the butterfly ones, most of them confuse the hell out of me.

But.

I'm finding it hard to understand wat alot of people are trying 2 describe in this forum, and I know theres probably several lists of wat all this means, but does any1 wana a slow "understanding" litle conversation about hyperloops?
