After years of this raging debate, I have determined the final answer.
Cheesecake trumps them both.
How much of a while? I found that you'd have to look directly down, because if you look elsewhere, you tend to fall in that direction.Originally posted by: OdiN
You know I tried to make an infinite falling portal in portal....but it was impossible. It would work for a while and then inexplicably shoot you out a little sideways so you didn't fall back in.

That, or put the exit portal to the side of the entrance, sending you flying straight up. It could be like a trampoline that way. 😀Originally posted by: Sphexi
That would be an awesome ride...imagine on a rollercoaster though, at the bottom of a big drop, they could make it go on for a long time, then shut off the portals. Awesome.

Too bad we don't have portals, or else we could finally have gravity-powered "perpetual" motion machines. Simplified, it would consist of a paddlewheel and a metal ball. Ball falls, hits paddlewheel, turning a generator. You could then use water instead, and do so on a huge scale. Imagine a hydroelectric dam with a self-filling reservoir, courtesy of a big portal.
Sweet, a portal-based microwave. 😀Originally posted by: jagec

And that is why they are impossible.
It's a problem for the concept of teleporters, too...if you teleport across a potential energy gradient, the extra energy has to come from somewhere, or go somewhere. While you can make up some rule about how much energy is required to actually send someone up or down, it's hard to see how this coupling could occur.
Some sci-fi authors have hypothesized that any potential energy difference would come out as heat. In other words, teleport "down" far enough, and you'll boil to death the second you step out of the machine. Ouch.
If a portal would somehow block gravity, even that would be incredibly useful. Antigrav devices, anyone? Manufacturers of wheel bearings would not be pleased.😉Originally posted by: Foxery
Aw, someone had to go and get technical.
If you created a vertically-looping pair of portals the way we find so amusing in the game, your velocity would actually be constant. Once you were inbetween thw two, there would be no gravitational force underneath you any more, and you would not accelerate. There is no potential to create energy; a machine would stop very quickly.
