Unplug the electricity lightfag

Please don't ever say that again

Fiber optic (glass) is an insulator and does not conduct electricity.

It can transport power but not very much or for a price that would be reasonable.

Yes, but why?

Yes but then you don't have electricity.

He's actually right you homos.
You can transfer power as light and then have a photovoltaic cell at the other end doing the same thing a solar panel does.
It has uses where you need total isolation and no RF interference but other than that as he said it's just isn't practical.

>the absolute state of Jow Forums

Kel, read that in his voice...

Yes but enjoy your 10% efficiency.

Yeah, all you have to do is put a solar panel at the other end and send a lot of data through and you should be fine!

you mean like, instead of having a car battery you just had a bundle of fiber optic cables? i dont think that would work

wow, look at these idiots

If you hook them in a loop you could store the light and then open it when you needed energy.

PoF (power over fiber)- can be very inefficient if we are talking over conversion over a typical data fiber standard.
However power over fiber using impulse currents/impulse lasers is very efficient especially over long distances and with far less safety issues with high voltage and no EMF noise. You could transmit packetized data too just with normal fiber.

The issue is you need to have nearly perfect glass and materials that can handle the energy involved. Typical lenses for very high output lasers can fail over a few uses. A transmission fiber has to be on continuously. There are obvious safety issues too with lasers that have the energy output to flash vaporize flesh too.

The amount of attenuation you're talking about makes it absolutely infeasible, and very unstable.

yes but it is absurdly expensive and incredibly inefficient, the system below for example provides 1 watt and consumes 75 watts

Sure, just put solar panels on the other end.

>is it possible to replace electricity with something that has a thousand times less energy

Yeah but electricity doesn't move at the speed of light

>electricity doesn't move at the speed of light
It's pretty fucking close.

Think of how many KWh you can save in the long run

The fuck? Are you trolling?
WTF happened to this place? When was it flooded with literal retards?

Neither does light in the fiber.

Exactly zero.

Light always moves at the speed of light
f the electricity's moving faster you save time though

he's right though

>Light always moves at the speed of light

no it doesn't

Yes it does. Don't conflate "the speed of light" with "the speed of light in a vacuum".

Unless you're talking about light's speed through a substance being slower than the speed of light, elaborate

nothing other than that. he just said speed of light is always the same, which it isn't always the same

>Light is slowed down in transparent media such as air, water and glass.

idc about vacuums, my house is clean

...

I spent 20mins looking for spdif cables and it turned out they are called toslink
Thanks for nothing

wtf? it literally shows up at the top of the page in google and the wiki is like second result in duckduckgo. All you have to do is type "spdif" in search bar. What are you talking about? 20 minutes?

>can I replace energy with matter
Sure, kid. Go ahead!

Matter is energy, dumbass.

Ooooh shiiet. We might be on to something Jow Forums

>f the electricity's moving faster you save time though
You don't.

Except it pretty much does
Have you taken a single physics class in your entire life?

>prettty much
Damn you sure got me. Tell me, how did "pretty much" do for you on your physics exams?

Speed of electromagnetic wave propagation in copper is 0.9c. Speed of light in glass is 0.66c.

yes, but you'd have to convert electrical energy to electromagnetic energy and then back to electrical energy. both have efficiencies of well under 50% so it would be a huge waste.

that's why you have erbium amplifiers along the way

ok so basically this board is /b/ tier retards larping as computer experts?

>have to use electrical repeaters in fiber optic cables over long distances adding extra power cost just to move data
>let's use it for energy transfer

You could do it for fun as a proof of concept, but it would never ever EVER be used for your intended purpose of "replacing electricity".

Ever shined a laser through a cracked fiber? Now imagine a 100W laser leaking through such cracks. It'd instantly catch fire.

It earned me a theoretical degree in theoretical physics
Also it doesn't matter how fast it moves, light still carries thousands of times less energy and is not viable in any way

I know user, I was just trolling

>woah! Oil has chemical energy, so-so-so, we can just replace wires with tubes and place tubes in circuits and and then just fill all the tubes with oil. Fuck yes, I'm a fuckinh genius
Please kys before you spread your mental aids to more people.

>store the light
Fucking hell. This is literally "fart in a jar" tier shit.

False analogy.

here's how you do it

Absolutely possible even today, with microwaves - using microwave waveguides and rectennas. It's even relatively efficient. But very bulky.

You could have a couple of thousand fiberoptic cables all connect together on a Solar cell. Then you purchase light on demand from a future company (since one doesn't exist now) to charge your cells. It would be much easier for them to transmit light to you since there is an abundance of it and then you can convert it to electricity and use your appliances.

A well built infrastructure could transmit more powerful light than what comes from the sun.

Fuck no. Even if we made photonic computers where the fuck would we get the coherent light for them?

/Thread

see a broken power line causes a fire /sometimes/, while a broken high-power light guide would cause a fire pretty much all the time
that and it's just not as easy to manage, you can quite easily power a gameboy from a bank of truck batteries using some bits of thin wire and a small voltage regulator, since the gameboy will simply only draw what it needs
what would you do with light? draw off a little bit of power and sink the rest off as heat? have some kind of two-way system such that the source is adjustable for the load required? the latter isn't really very feasible outside of small/custom/closed circuits, which would almost certainly not benefit from light-based power transmission

lol

Yes it is possible. But, theres a big but i cannot lie.
You would need to replace the entire electric infrastructure to do that.
An interesting idea non the less.

That is not using light as electricity. Which was the question.

This thread has to be a troll.

You don't have to transmit infrared and ultraviolet. Solar cells could be designed specifically for this purpose for using more colder light. With advancements in material science, this is inevitable. Just because you can't envision a safe way to it doesn't mean other people won't make an attempt. That's how science works.

Photons are the most abundant things in the universe. They have no mass and literally travel at the speed of light. Electricity is inefficient over long distances. Light can travel across galaxies.

Its a good question and there are good answers. Go back to your GTX porn if you want.

You have the double think down pat don't you.
Light is either real or it is not. Reality is always effected by Reality. Light doesn't just exist in the lab you know.

No. because the light would be instantly turned off.
just like power lines do.

that's only one of the two points i made
the second point is how a light-based system would be based on 'pushing' light from the source, while electricity is 'pulled' from the source
'pulling' from a source has great advantages in variable load applications, which is most things, including a mains power grid
ask yourself, how much light should a home be supplied with? too little and things wont work, too much and the excess must be wasted. a house doesn't use a constant amount of power, it's always fluctuating, so you're either;
a. supplying enough, and wasting a lot of power
b. adjusting the supply dynamically to suit the load, wasting less, but increasing the complexity of the system

at absolute best i can imagine light power to 'last mile' substations, then copper for the last mile, but that's assuming this can be made more efficient than existing electricity transmission, and at least as safe

You can "pull" light as well. Everything electrons can do photons can do better. When it comes to energy transmission.

>You can "pull" light as well.
how?

Electricity isn't just the "flow of energy" you mong. It is the flow of electrons. We don't use batteries just because it has energy "stored" in it. We use it because it can push out electrons due to the chemical reactions that occur inside it. Your "theory" is no less retarded than drenching hardware in oil or leaving copper wires in sunlight to
>make photons hit it and cause electricity, hurr
Go study what solar panels actually are and for what reason they exist in the first place before bullshitting with "muh sloar powa!"
Even if this is a troll, this is beyond autistic.

Excellent thread OP! Elegantly trolling Jow Forums while sounding like a retard.

>Electricity is inefficient over long distances. Light can travel across galaxies.
what are you talking about
EM waves are just have the same attenuation as light
Or is your argument cables vs. wireless transmission?

Using photonics for anuthing is a meme, fiber are like mirrors within mirrors and light will just get infinitely trapped

10/10 baito

there would be no performance gain. electricity already travels at (basically) light speeds.

I'm sorry, but what you said makes absolutely no sense what so ever.

Power lines have circuitry for that, and you can actually detect that something broke at the source. Not possible with light, it'd require feedback from the receiver.

If you mean for computation than yes. There's tons of research going into optical computing but it's shit in pretty much every aspect compared to electric computers.

Probably works better with a maser.

Yeah, they are intended to be used in single mode. Like optical fiber basically.

So what you are saying is that there is nothing faster than the speed of light? whycome?

>woah! Oil has chemical energy, so-so-so, we can just replace wires with tubes and place tubes in circuits and and then just fill all the tubes with oil. Fuck yes, I'm a fuckinh genius
We already do that. They're called combustion engines. Are you retarded or something?

electromagnetic radiation in any frequency or magnitude is magic. Physics doesn't say why, its just a ruleset about what we've observed, and how it behaves. The internet, and the device you and I are using, and tons of other things are built using what is essentially well understood and described magic.

>So what you are saying is that there is nothing faster than the speed of light?
Yep.

Stop being retarded.

He clearly is, don't waste your time anymore.
