star trek - How much energy could the Enterprise-D produce?


Just watched TNG: The Dauphin. In it the following exchange occurs when receiving a powerful transmission:




Data Sir, sensors indicate the communication originated from a tera-Watt source on the planet
Riker That's more power than our entire ship can generate!



This seems silly.



  • There is currently a hydro power station that produces 22.5GW. 50 times that seems very large to us today, but when you consider the biggest nuclear weapons can release 0.5TWh, the numbers don't seem that extreme.

  • Shields! Phasers! 150KW defensive laser systems exist. A 1PW laser accelerator is a thing. Those on the enterprise must —by virtue of needing to go much further and charge much faster— need more power.

  • Transporters! Replicators! The holodeck! Surely the converstion of energy into matter and arranging that at distance, must pull a lot of power. And it's happening all over the ship, all the time.

  • Impulse engines. Even in a vacuum, shifting 4.5 megatonnes must take serious power. To accelerate 1m/s over a second, you're looking at 45GW and they seem to do things much faster, all the way up to 75,000,000m/s. Full impulse seems to take a few seconds... That makes my calculator cry, with numbers around 8 ×10^24W... That's way over.


  • Warp.

  • Computer.


All of that, while keeping the lights on running other day-to-day things.


Was Riker just off by a unit, or is there something I'm not factoring into these points? How much energy could the USS Enterprise NCC-1701-D produce at peak output? Are there listed energy requirements for the components above that I've been guesstimating for?

harry potter - Did Dolores Umbridge Have Any Association with Voldemort (or Death Eaters) before His Return?

I noticed that Dolores Umbridge was born during the first Wizarding War, so it's very likely she wasn't a Death Eater then (but she is pretty evil -- who knows?). After that Voldemort was not around in a way that could affect many people, and most wouldn't know he was planning to rise again. During that time, and up through Voldemort's return (in Goblet of Fire ), did Umbridge have any connection with the Death Eaters or with Voldemort? Was she doing what she did on her own, or was it because of an association with Voldemort or his allies? Answer Dolores Umbridge was definitely not a good person. However, as Sirius points out, "the world isn't split into good people and Death Eaters". Remember that he also says that he doesn't believe Umbridge to be a Death Eater, but that she's evil enough (or something like that). I think there are two strong reasons to believe that: Umbridge was proud to do everything according to the law, except when she trie...

What is the etymology of Doctor Who?

I recently decided to watch Doctor Who, and started viewing the 2005 version. I have the first two episodes from the first season, and I can't help but wonder what is the etymology of the name "Doctor Who"? And why does the protagonist call himself "the Doctor" (or is it "the doctor")? Answer In the very first episode of Doctor Who (way back in 1963), the Doctor has a granddaughter going by the name "Susan Foreman", and the junkyard where the TARDIS is has the sign "I.M. Foreman". Barbara, who becomes one of the Doctor's companions, calls him "Doctor Foreman" (probably assuming that is his name given his relationship to Susan), and Ian (another early companion) does the same in the second episode, to which the Doctor says: Eh? Doctor who? What's he talking about? "Foreman" is most likely selected as a convenient surname for Susan to use because it happened to be on display near where the TARDIS landed....

story identification - Animation: floating island, flying pests

At least 20 years ago I watched a short animated film which stuck in my mind. The whole thing was wordless, possibly European, and I'm pretty sure I didn't imagine it... It featured a flying island which was inhabited by some creatures who (in my memory) reminded me of the Moomins. The island was frequently bothered by large winged animals who swooped around, although I don't think they did any actual damage. At the end one of the moomin creatures suddenly gets a weird feeling, feels forced to climb to the top of the island and then plunges down a shaft right through the centre - only to emerge at the bottom as one of the flyers. Answer Skywhales from 1983. The story begins with a man warning the tribe of approaching skywhales. The drummers then warn everybody of the hunt as everyone get prepared to set "sail". Except one man is found in his home sleeping as the noise wake him up. He then gets ready and is about to take his weapon as he hesitates then decides ...
