Stupid things Trek/Wars debaters say.

[KSW]

It's not like a cloaking device only hides you from EM based sensors.

Of course not, those would be useless at warp-speeds, and equally useless at sublight due to delay in bounceback.

Spock never said the energy requirements were beyond any ship. He said the expected requirements were large, and implied the expected requirements to beyond the Romulan ship

Yes, unless they had found a way around it.
Clearly they did; since the last encounter between Romulans and the Federation, the Romulans had developed better weapons and stealth, while the Federation had developed faster ships.

Also power comes from anti-matter, not the type of engine using it; the Romulan plasma-weapon was powered by anti-matter, so there's no reason their engines couldn't also use it, and produce the same amount of raw power as Starfleet engines.
Warp-speed, like the cloaking device, simply used power more efficiently rather than simply generating more, allowing the ship to travel faster on the same amount of energy as impulse.

The Enterprise Incident
SCOTT: It'll have to hook into our deflector shield control.
Cloaking devices just plug into the deflector shield controls. This means that at least Federation ships come read to cloak out of the box.

Or their technology was compatible, now that the Romulans were using Klingon-design ships. Scotty would know all about those, since they had just come out of a war with the Klingons; he'd also be up on all the intel about cloaks, since obviously the Fed had given up on building their own if they had to stoop to false-flag espionage in order to steal one.
Starfleet intelligence also obviously calculated that the cloak would be compatible with the Enterprise's deflectors, they never would have attempted it on blind dumb luck.
They might modified the ship's deflectors to be compatible, who knows; Starfleet isn't exactly staffed by idiots like in Picard's time.

That meant that the Enterprise was faster. Romulan torpedo-weapons were superior to the Federation's phaser-guns, as was their cloaking device superior to federation technology. (This episode was analogous to German subarines in WWII BTW)
Warp-drive doesn't give more power than impulse, it simply allows the ship to move faster on the same amount of energy IIRC. They both get their power from anti-matter.

Balance of terror
Scotty: No question. Their power is simple impulse.

Scotty was talking about reactor output. Impulse only requires fusion reactors which are less powerful then warp core

That's what I said.

Warp-speed, like the cloaking device, simply used power more efficiently rather than simply generating more, allowing the ship to travel faster on the same amount of energy as impulse.

Impulse engines are always shown to be powered by fusion reactors. Impulse engines have much lower power requirements, but much lower top speeds.

Warp drives are powered by black-holes or matter/anti-matter/dilithium reactors.

Or their technology was compatible, now that the Romulans were using Klingon-design ships. Scotty would know all about those, since they had just come out of a war with the Klingons; he'd also be up on all the intel about cloaks,

Scotty is basically plugging the cloaking device into a USB port.

since obviously the Fed had given up on building their own if they had to stoop to false-flag espionage in order to steal one.

There is no evidence for this claim. Just because the U.S.A. wanted to capture German sub, Zeros, and MIG fighters does not mean they could not build their own.

Starfleet intelligence also obviously calculated that the cloak would be compatible with the Enterprise's deflectors, they never would have attempted it on blind dumb luck.

The UFP is repeatedly shown to have spies in the Romulan Empire..

They might modified the ship's deflectors to be compatible,

The Defiant was just as compatible with Romulan cloaking devices as Kirk's Enterprise was.

who knows; Starfleet isn't exactly staffed by idiots like in Picard's time.

You need to mark your examples of stupid claims better since this takes the cake.

[Roondar]

About Starfleet vessels being 'invisible' to 20th/21th century technology, I distinctly recall that each such a feat was actively ordered and AFAIK affected radar etc only, not the actual visual image.

Which would explain why you could see the Enterprise quite well in ST:FC.

I'm also certain that Starfleet has thought up and build cloaking devices (witness the whole business with the USS Pegasus), but is not actually using them.

[Picard]

Starfleet has technology and know-how to build cloaking devices, but treaty with Romulans prevents them from doing it.

As I said before, the E-E was damaged, and they knew it. Heck, they might have let them see the ship like when Kirk scared the crap out of the whalers.

"Star Trek the Next Generation: First contact" would disagree. The entire episode the Enterprise-D stays in orbit around a planet where they are about to build their first warp drive. Riker gets hurt, and everyone starts panicking about an alien invasion, but no one sees the Enterprise-D in orbit.

"Star Trek: Tomorrow is Yesterday" has the US Air force spot Kirk's Enterprise in the atmosphere. They leave the atmosphere, Spock turns on the shields, and no one can find them. Stealth and radar counter measures have been around since radar was first used way back in WW2. Do you honestly think there weren't people trying to find the ship with telescopes, binoculars, and the naked eye in that episode?

Spock and Sulu spot a cloaked Klingon ship on the view screen with their eyes in "Star Trek: 3 The Search for Spock" as I recall.

I'm also certain that Starfleet has thought up and build cloaking devices (witness the whole business with the USS Pegasus), but is not actually using them.

That has to do with treaties, but if Star Fleet was using cloaks we the viewer wouldn't know about it anyway because none of the series cover black operations really.
