Problem with portals for international travel:

If you had an entry portal in the USA and an exit portal in China, and there was low air pressure that day in China and high air pressure in the USA, opening the portal would send through winds at about a thousand km/h and destroy the building in China and pretty much splattering the traveller all over the Chinese countryside.

Solution? Airlock wouldn't really work because the pressures would still be there, and depressurising would give the traveller the worst case of the bends ever.

I believe you have no fucking idea how air pressure works.

what would happen then?

A light breeze and possibly a violation of the findamental laws of physics

Whoa buddy, I mean yea there might be a difference in air pressure between some areas, but not as bad as you say that would cause a 1000 km/h draft.

I mean we're assuming this portal is a doorway from two points. the air would be flowing in between both just fine.

That's altitude.

Oh fuck man, you don't wanna mess with those. That shit will fuck you up.

Not if it's on the runway still.

I can't speak to the pressure differences turning into wind speeds, but as far as the bends, the difference in pressure between space and the surface of the earth is one atmosphere, which is the same as the difference between the surface and 30 feet under water. If there was a significant difference in pressure between the two places, the worst that would happen is that it would make your ears and sinuses hurt until you equalized them.

Typo.
