Trust you...you dragged me into this mess to fight Princess Erroria! How can I trust you after that?
...Very easily, as it turns out. I'm to lazy to actually look it up.

Lyra is playing with portals.
6368099
Hello... my name is BuckDos. Are you ready to begin testing?
Watch out for my spider golems.
A hoof sized teleportation portal is one thing.
A hoof sized lubricated teleportation portal is another.
The latter can violate so many things.
6368108
Clearly, it isn't perfected just yet.
I'll let it go since it's fiction and you already said you don't believe it, but air friction and gravity would eventually stop that ball in the middle of the portals, assuming the portals don't affect the speed of the ball at all
best kind of science... MAD SCIENCE
6368135
I would imagine that sealing the system off in a vacuum would help. I foresee LOTS of problems in the long term. But the theory itself is sound enough. The execution would reveal all kinds of long term problems.
Does anyone else think that this might end like Chernobyl with the machine overheating and what not?
6368107 I read that in Wheatley's voice.....
I would like to thanks you, kudzu, for all the enjoyment you provide to us.
Sorry for what you have been through in the last days. i write nothing ´cause...I really have nothing relevant or helpfull to say. In the other hand, you always have something good to wirte for us, that make our day better. And believe me, with all the problem my country is going through, I really need something like your work to help reach the end of the day.
Thanks.

So, is this an infinite source or only practically infinite? For it to be infinite, magic has to be infinite.
6368142 All the good stuff comes from those who are mad. usually
6368281
Tesla comes to mind.
6368254 This is what I was thinking too. Where does the ley line energy come from? How much actual energy does it take to create and sustain the portals? It would be true infinite energy if the electricity produced powered the portal. Any excess electricity would be a bonus from the device.
6368314
Depends on how cruel the author feels to the inhabitants of the world. Ones who are particularly cruel treat magic as, in the end, a finite resource just so there's a looming doom to Equestria's way of life as an arbitrary screw-over for magical ponies.
Others treat magic as being something akin to the water cycle. Gathers in leylines where it's drawn through living things and dispersed into the environment, where it returns to the leylines.
6368314
Electricity can't power the portals though. The portals are powered by raw magic, done with a trickle charger from the ley lines. It keeps the portals open.
6368353
In this verse, as it has been revealed in the story... ley lines, some of them anyway, are extra dimensional. They go through the planet, but there are also lines that move through the universe and other planes, like the astral plane.
6368363 So basically, as long as the Multiverse is infintely expanding by new cosmic gods coming into power and creating their own worlds, there will always be magic going through the Ley Lines. Is probably also how the portals work. The Ley Lines cause there to be some link that allows for the creation of portals to other worlds/dimensions
6368404 So based on that, the ley line is an infinite source of energy. The trick is where/how to harness that energy.
Jeez, he can't even listen to joyful cries? Luna, you bucked up.
Also... given the fact that... if the Shadowbolts are anything like the Myrmidons... does that mean that everyone who's going to go through the project is now, first and foremost, a weapon? That they are going to be barely-controlled killers, restrained mostly by a ton of emotional controls?
I'm going to go back to my old stance that doing things for survival that involve doing something to yourself that requires emotional control to stop is a bad plan. Hell, I don't like the emotional control at it's base, so a plan that necessitates it is abysmal.
6368454
The ley line is an endless source of magic.
Earlier in the Chase, Twilight made some arcano-tech batteries that recharge with vibration, and the vibration comes from magical power.
They're low power, but so long as the draw isn't too bad, those batteries will run for a long time.
6368471 Ok thank you for clarification. I had forgotten that fact. That clears up my confusion/suspicion on Lyra's discovery.
6368468
Actually, for PTSD sufferers, hearing any sort of startling cry is troubling.
Luna could actually fix this, but she is unable to get inside of Bucky's head.
Hmmm Lyra, the alicorn of mad science sounds pretty cool.
6368519
It's not Luna-inspired-foal-obsession caused, but like... actual event caused?
I see.
6368135 Ah... why would gravity stop it? Wouldn't it, y'know, keep pulling the ball down?
6368495 The best way to look at Lyra's invention is less a source of infinite energy, and more as a method to convert the infinite magical energy of ley lines and the gravitational pull of the planet into electrical and thermal energy (via mechanical energy; woo, science!).
6368633 6368143 6368135 Gravity would not stop it as long as the tube remains parallel with the direction of gravitational pull. While evacuating all of the gas from the drop tube would alleviate the friction induced heat build up, the lack of resistance would eliminate the braking effect on the sphere, allowing for gravity to accelerate it indefinitely.
If the gravitational constant is the same in the Chase as it is here (and for simplicity's sake, let's assume it is), that metal ball's going to accelerate at ~9.92m/s/s, minus any other external factors that may act to retard the velocity gain (the magnetic field which is generating the electricity would retard the acceleration to some extent; not going to try to calculate how much, there's too many unknown factors). Which means it'll be moving at orbital velocities within a minute or so. Within an hour it'll be moving at a significant fraction of C. That....would be bad Maintaining one standard atmospheric pressure would limit the velocity to a much more reasonable level, probably about 140km/h (ballparking again, not calculating).
I can see them having all kinds of fun figuring out the engineering to make these practical and efficient. Hooray for mad science! Hopefully there are no catastrophic failures, that would make me sad.
There are Stirling engines also that could be utilized. They work on heat difference between two parts of the engine. Bigger the difference, the faster they run.
6368778
Ooooh, explain more!
...because most of those things are things I know not. Specifically, whatever C is.
6368834
C represents the speed of light.
6368855
Ah!
Hmmm... in that case, with enough- infinite- time, wouldn't it theoretically reach C?
6368778
Would make a great bomb, wouldn't it?
Suddenly, BLACK HOLE!
Observations on Lyra's device that I currently see:
I find it odd that the object is a ball and not a cylinder, spherical magnets are weird. (Think of a typical NS bar magnet and then apply to a sphere). Only advantage I can see is even air resistance, but since the magnetic field of the ball is the important thing I would think that the ball shape would not outweigh simply having a cylindrical magnet.
Device would be producing DC current. Has upsides and downsides compared to AC, not getting into that now. (Not even sure if AC current has been invented on Equus or not)
Alternate Application for portal tech as gravitational rail-gun may be possible if exit point can be reliably switched between passes. May be accomplished by changing the orientation of the exit portal between passes, moving in second set of entry/exit portals that would be aimed at target, or switching what portal it exits out of (would require capability to cycle connection of an entrance portal to multiple exit portals).
In Air filled tube;
Ball will have terminal velocity due to fixed gravity and air resistance. Hopefully this will prevent runaway speed buildup and create maximum output based on this speed and the amount number of coils it would pass through.
Gravitational orientation (since this relies on falling) or jostling container could have problematic effects. Because it is gravity reliant, could possibly (big if) be stopped by turning device upside down until ball stopped spinning. More detailed next.
Not certain of math involved at this time, (been a while since E&M) but if the induced magnetic field of the wire doesn't hold the ball nearly perfectly centered in the cylinder as it passes, the ball may hit the sides of container and rattle around. Also could be caused by container not being perfectly in line with gravitational vector. This could cause catastrophic damage at high speeds. Would have to check vector math. May be dependent on relative geometry of falling magnet, tube, and coils.
Heat buildup from air friction will need to be tested. Depending on terminal velocity of the ball and the properties of the involved materials, possible failures include melting of the wires, cylinder, ball, even the ignition of the air (unlikely but possible). Dispersal of this heat could be used to power steam engines, but there is still risk of the interior air and ball being negatively affected by the heat. (deformation, loss of magnetism, auto-ignition)
Heat will also simply buildup from the electricity flowing through the wires, output from this should also be measured, as hot wires will have greater resistance and their productivity may be impacted. May also affect falling magnet.
In Vacuum Tube:
No significant restriction on fall speed, object will continue to accelerate.
Runaway current will certainly cause critical failure of components if anything is even slightly out of alignment.
Ever-increasing current will eventually outstrip any system that could diffuse heat.
Forcing current in opposite direction as it was being generated could potentially create a magnetic field that slows down and eventually repels the falling object. This maneuver would be complicated if possible at all and very mathy.
6368878
No. But it would suddenly weigh as much as a star. And would keep getting heavier.
6368896 i
What would be the limit to its heaviness?
6368921
Not sure. Would start warping gravity and time around it.
6368931
I will put money to this being used as a weapon.
Actual money.
Because if you didn't, we would all be surprised, not to mention kinda dissapointed.
Back on track, how will Lyra stop this from happening?
6368778 couldn't you use nitrogen or some other vaguely inert gas to keep it semi frictive while at the same time slowing the velocity to a value less than c? And to those scientist out there I know mass is a thing but what gasses have the biggest mass vs non kinetic values so that friction could occur but also limit the heat buildup so that making a boiler or something from such a device wouldn't cause it slag out. I know gasses as a whole vibrate the fastest out of all the molecules, so picking a gas that isn't non thermic but vibrates at the correct frequency would be a must in developing such a device.
6368931
Also, you're currently at about 2.8k or so per chapter as an average if you're going for it.
6368891
Addendum: The following hypothetical is crazy complicated turbulent compressible fluid dynamics problem so I have no idea what could be actually happening. This is just a couple limited guesses, but should get across the point of how crazy this thing is. Hypothetical is subject to relative dimensions of the falling ball and the tube.
Also of note, fluids in motion experience a reduction in pressure as velocity increases, (Bernoulli's principle) but I don't know enough about fluid dynamics to know if it could even be applicable in this situation.
If the air in an air filled tube can pass through the portal, then the ball's motion causes a wake effect, Pushing air in front of it and pulling the air behind it. This fluctuating pressure differential will have weird effects.
Eventually the ball and the air could be moving at such a speed that the air "behind" it is at a higher pressure the air in "front" of it, this would cause the trailing air to actually start pushing the ball forward, accelerating it faster, while the lower air pressure in front providing less resistance to acceleration.
Alternately, the ball and the air may end up going the same speed, since you could basically think of the entire contents of the container falling as a single object through the portal beneath it (everything is falling). Or this effect could possibly be lessened or even cancelled by the air at the top trying to expand upwards and pushing against the air at the bottom trying to expand (and fall) downwards.
I'm going to be talking to my professors about this next week to see if any of them have a clue as to all what could be going on here. This shit be crazy yo.
6369052
I just don't know what went wrong.
I just had a very silly idea.
Lyra just can't make anything beneficial...only destructive...poor girl.
I just saw this a day or two ago
6369073
Oh, you can totally ignore most of my posts by saying "magic" or just having them work it off-screen. I just saw physics thought problem and couldn't stop myself.
Everyone(who hasn't already) say it with me now:
Now Lyra's thinking with portals!
6369106 Welcome to Lyra´s mind, it is contagious and uncontrolable...first sympthon: trying to apply real world phisics with pastel colored ponies magic...and asking your teachers help on it.
No turn around...too late !
6368594
Goodness Radi, it sounds like you're... jumping at shadows.
The Lyra Class of Physics is AWSOME.
Bad thing about trying to break the Laws of Physics.
They tend to end up breaking you!
