No Conservation of Energy: Difference between revisions

** {{spoiler|Relativity allows for all sorts of crazy things to exist, including wormholes that join different regions in time and space (FTL travel implies time travel). Having stuff travel into the future seems positively safe compared to inertialess FTL drive system, seeing as it doesn't even cause any paradoxes}}.

* In ''[[The Dragon and The George]]'', the trope is either slightly inverted or subverted. Speaking on the subject of the power available to mages, the wizard Carolinus irritatedly says (paraphrased), "Just because a number's infinite doesn't mean you can use it to get something for nothing." (This may be true in this universe, as he's apparently referring to Cantor's hierarchy of infinities, and spells may require infinite expenditures.) As with the ''[[Young Wizards]]'' series above, later books note in the background the development of ways to tap new sources of power, some of which probably provide infinite energy, but which still avert the trope.

** [[Antimatter]] is pretty much impossible to contain in real life. You'd be hard pressed to find a less portable energy source.

* Lampshaded in ''[[Firestarter]]''. After a government experiment in which Charlie McGee vaporizes a cinderblock wall with her pyrokinetic powers, the next chapter is an Interdepartmental Memo in which one of the evil government scientists points out to the head evil government scientist that, despite producing 30,000 degrees of spot heat, the nine-year-old girl in question burned about as many calories as if she were reading a good book--leading the seriously weirded-out scientist to wonder just where the hell the energy is coming from (and to start thinking about stuff like black holes and things we breathe a sigh of relief that we can only observe from millions of light-years away and pretty much wondering if this little girl is some kind of rift in the very fabric of the Universe).

** All the details of Pokemon biology that come with each Pokedex entry might as well just not exist. Anyone with half a brain should know that Pokemon shouldn't continuously exhale water as if they're attached to a hose or a pipeline. How does Squirtle store all that water into its tiny body? Flapping your wings can realistically create a gust of wind, but it would also send the offender flying backwards.

*** Considering that the Pokemon universe (and, presumably, laws of physics) was created by a Pokemon, this might be a case of [[Screw the Rules, I Make Them]]

** It gets even worse with the above example. Two logistics ships can transfer 324 GJ of energy every few seconds to each other while only using 108 GJ each to do it. This results in each ship gaining 216 GJ of energy every 5 seconds that literally comes from nowhere.

*** Another example would be the "Thermodynamics" skill description: "Also gives you the ability to frown in annoyance whenever you hear someone mention a perpetual motion unit."
