If you could put two portals anywhere?

[i7omahawki]

Bedroom -> toilet...

Make getting up in the night that much easier.

Okay, it may not be fancy, but it'd be worth it damnit!

 

[Queltherio]

The ceiling and the floor. Wheeeee!!!!

 

[Outright Villainy]

Well, being pragmatic, I'd put one extremely high up, then one directly beneath it at ground level. Now, by breaking the laws of energy conservation, we have infinite potential energy, and shall build generators around it.

[sub]Problem, entropy?[/sub]

Entropy wouldn't be a problem with the perpetual motion device itself. But, if you keep adding more and more energy to the universe it will increase the speed at which we reach heat death.

See portals bring Armageddon I knew valve was evil.

But entropy increases for all closed systems, and in this system where gravitational potential is a constant, useable kinetic energy is just coming out of nowhere, decreasing entropy for that system. So I very much think entropy would have a problem with it.

Because it's more than just perpetual motion, it's increasing motion, and the energy that goes with it.

 

[StellarViking]

Bedroom and somewhere way, way out away from cities and lights so's I can watch the stars at night without glaring stadium lights messing up my view.

 

[GrizzlerBorno]

Wall next to my desk. Inside of a Grocery store Drinks Fridge.

 

[Sir Broccoli]

The bottom of the ocean and the surface of the moon.

Just to see what would happen.

Dammit! I was going to say the exact same thing!

Oh well, guess I'll just do this then:

Spoiler

(The slide thing, not the bathroom thing)

 

[Spartan448]

Orange portal in Black Mesa, Blue portal on Moon. Black Mesa can kiss my bankrupt a -recording cuts off-

 

[fooddood3]

Most likely on the moon and a specially constructed location.

Place a big, heavy block/door/wall type thing over the Earth portal, hook it up to a heavy-duty mechanical arm, and set airlocks in the room.

Long story short, now we don't have to deal with the Earth's much bitchy gravitational pull and thick atmosphere to get our stuff into space. Just take your materials to the moon's surface, construct it there, and fly off to Mars.

There, I just saved BILLIONS in rocket fuel.

Whoops, someone forgot to close the door, there goes the Earth's atmosphere.

 

[The Artificially Prolonged]

Also, next to my pc and one in the fridge, preferably as close to the beers as possible.

Damn ninja'd

1. Open portal at bottom of a lake or reservoir system
2. Open portal in middle of a desert
3. Sell the "miracle desert water supply" for high profit, taking advantage of "mysterious water shortages" around the glode
4. Evil laugh

 

[SovietSecrets]

My room and a room in my Uncles house in Russia so I can visit whenever I wanted and they could come here too.

 

[CRAVE CASE 55]

one inside my fridege and the other on my coffee table... Never have to get up during a movie again

 

[Urgh76]

I'd use it to screw with people. Because it would be fun as hell.

Also, maybe this:

Oh my god, I can't beat that

 

[Blaster]

Any room to the backstage of the victoria's secret fashion show.

 

[Harry Mason]

One in my house and another in Helena Bonham Carter's shower.

 

[tommy15994]

One at the bottom of a deep sea trench, the other at the top of mount everest. Greatest. water slide. Ever.

Or one in my room and the other in city (i live in the country-side, middle of nowhere) Easy access to Town, no need to ask parents for lift. Result. also you may not have seen this but

^^ Portal mirrors

 

[RA92]

One under my bed, and the other on <url=http://masseffect.wikia.com/wiki/Thessia>Planet Thessia.

Asari booty oh yeah! >

 

[mysecondlife]

One in my house and another in Helena Bonham Carter's shower.

that probably also equals Tim Burton's shower.

so. eww.

 

[Captain12345]

Yeah something like that.

That...was exactly what I was going for, though I wasn't aware there was a troll face animation hahaha.

 

[Polyg0n]

I'd put one into my room wall and another one to my former host familys house in Japan. Would save me a lot of money and time on flying.
