Place it in a vacuum and see how long it can run for after the light is removed, I would like one of these


Apprehensive_Fly_489

I'm curious to see it in a vacuum with a perpetual light source. I wonder if there any space applications for this 'toy'


ghettithatspaghetti

What is a perpetual light source? Regarding space applications: the only thing we do today in space that requires a lot of mechanical rotational energy is in reaction wheels, so someone may propose it as a replacement (with the proposed benefit of increasing electric efficiency by not needing to store as much power in batteries?), but implementing reaction wheels this way would be less efficient than how it is done today because your 6 solar panels you lugged up into space are ~1/4? as effective as they could be (one fully exposed and 2 partially exposed to the sun at a time instead of all 6 fully exposed) and so youd probably end up needing more weight than the batteries you displaced. Additionally, this is much harder to control (only works if sunlight is hitting your reaction wheel, which you really want in the center of your craft), you'd need additional electronics and design considerations, further reducing your efficiency and increasing weight. Also, if you're in a situation where solar is a viable source of energy, you probably get enough of it. Many space applications cannot rely on solar energy, and instead use radioactive power plants.


Tobuntu

I could be wrong but i think those magnet poles (talking about the donut magnets on the ends) are aligned so they are not a constantly changing field, which is what generates electricity. Otherwise it would not have a stable force levitating it. One pole points toward the solar panels, one points away. A rotating magnetic field off the same magnitude

Living_Hearing8377

“probably doesn’t generate more electricity” is quite an understated way of saying that


Mammoth_Echidna2166

In this case electromagnetic field --> movement instead of movement-->induced field. It's a gradient, so maybe you could siphon off some energy with gearing, but the losses are gonna make but worthless. Better to put all that energy into spinning around and looking cool that trying to charge your phone.

_clem_fand_ango_

Seen something similar before. It was anchored at both ends though and moved a bit slower. Google rotisserie chicken.


_Romove1_

a motor that spins at the same time as the axel wouldent be very useful..


Gurk_Vangus

the energy needed for the magnetic field would probably use more energy than the setup is producing


raggedy--man

For a hypothetical commercial application, they could probably skip the levitation part and just use normal bearing housing for the shaft


IHeartBadCode

Could just skip the bearing housing too and just move straight to the blackjack and hookers.


bythenumbers10

I don't think blackjack holds up well under those kinds of stresses.


Ryanhis

The hookers should be fine though


bythenumbers10

Well, they're used to supporting their illegitimate children, what's a green energy source to add? XD Seriously, though, #legalizeSexWork.


Gurk_Vangus

maybe doing some solar farms in deserts ? just an idea like that


raggedy--man

You can use traditional solar panel and motor combination if you have the space for it. Im not smart enough to figure out if this rotating solar motor thing could be an actual viable thing with better output than a normal dc motor running on solar power. But theoretically you could use something like this if you're limited on space. I think


CalmTempest

The sides not facing the sun are wasted material because they're not getting optimal sun. It's most likely just a novelty idea.


PaurAmma

But then you have to get the energy from the desert to where you actually need it, if you can't use it close by. [There's a good video about it from RealEngineering,](https://youtu.be/7OpM_zKGE4o) and others as well.


ScottColvin

That is what I was wondering. If you're not electricity, but solid magnetics. How big could you scale it up. And my real question. Even at this scale. Do magnets stop being magnets at some point? Or do they always keep there polls and strength. If this was going fast enough, with my limited knowledge, they should become demagnetized or super magnetized? Is it heat that might destroy a solid state magnet?


Gurk_Vangus

Magnets are element (iron, cobalt...) which developped ferromagnetism. if you transfer this energy somewhere else (law of conservation of energy) they can loose their propreties. For this kind of machine with this kind of scale, you can't use magnets (like the kind you put on your fridge) but you have create a magnetic field using energy (sending electricity inside a wire).


ScottColvin

Not sure about the downvotes there. Did my best with an upvote. Groovy, thanks for the info. Fascinating stuff.

Gurk_Vangus

well, i don't know neither, sometimes people downvote for no reason, especially that you don't have to give any reason why. i usually don't care about them. You are welcome, i asked myself same questions before too, i read some stuff about Cern laboratory which as (if im not mistaken) the most powerfull magnet we could produce yet (https://home.cern/science/engineering/pulling-together-superconducting-electromagnets) , there is aswell the one they are making for fussion reactors https://www.newscientist.com/article/2280763-worlds-most-powerful-magnet-being-shipped-to-iter-fusion-reactor/


ScottColvin

Well that's just shnazzy. Thanks for the link.


CimmerianHydra

If I remember correctly from my condensed matter physics, this isn't quite true. The end result is the same but the process is a little different. Ferromagnetism is already the "lowest energy state" of some materials like iron; that doesn't make them emit a magnetic field. What actually is responsible for the magnetic field are so-called "magnetic domains", regions of the materials that settle down in such a way that they do act as little magnets. The problem is that in normal conditions (like regular iron you find lying about) these domains are randomly distributed and hence will not coalesce into a stronger magnetic field. On the other hand, properly magnetised objects have large domains that more or less align, hence they form a stronger field when taken together. Now, the act of using the magnetic field to perform some work simply *scrambles* the magnetic domains. The energy of the system is roughly the same (yes it will decrease a bit), it just settles down in a different way with less domains aligned together. If this goes on, the material eventually de-magnetises. Moreover there are crucial differences between a magnet that is such because of the material and a magnet that is such because current is being applied, I won't go too much into it but they behave in a different way.


PaurAmma

To specify, ferromagnetic materials are materials that exhibit relatively high remanence and thus a permanent magnetic field due to small areas within the structure of the material which can be aligned with a strong magnetic field during production, and stay that way (mostly).


IGetItCrackin

Solar levitation is an energy-free form of transportation by which we capture the potential energy of the sun's energy (i.e. harness) and channel it into a propulsion system. It does not use fuel or other energy source, relying instead on the energy from the sun that would otherwise be wasted in transmission to a power plant. While the exact definition of solar energy is debated, it is generally accepted to be an infinitesimal quantity of electromagnetic energy released throughout the course of a solar eclipse, that would be stored in mirrors and collected in a special battery. However, if a sufficiently large power array is built within the field and is operated at a suitable rate, then it can produce sufficient energy for such a system. If one wishes to go further with the solar-light levitation concept, it is important to have the proper magnetic field to capture energy and use it to power the levitation system. There are a variety of options for a basic solar levitation battery system, including conventional high voltage battery cells that have been optimized for the purposes of solar-light levitation.


a_ninja_mouse

wtF are you on about


ElectricFlesh

I understand all of those words, and a few of them actually mean something, but not in that order.


Gurk_Vangus

i understand the appeal of collecting solar energy and at the same time creating a dynamo, but still, charging the magnets to allow the rotation will consume too much energy. you would not harvest solar energy but mostly transfer and collect the energy you are using for the levitation, and losing some at the same time. i don't know what you are talking about... "infinitesimal quantity of electromagnetic energy from solar eclipse"?


raggedy--man

I think solar levitation is just magnetic levitation using solar energy. Like mag-lev, but using a solar energy grid. The current maglev trains draw their energy from the normal existing power grid systems. So any solar grid with same capacity will cover the maglev requirements. Infinitesimal is very different from infinite. So im thinking he means the loss of solar radiation due to the sun being covered for the eclipse duration. But i think the night time redundancies should cover the eclipse, so im also not sure what op means


Libran

Whatever you're smoking, you should probably use less of it.


Fez_and_no_Pants

Or more.


South_Dakota_Boy

Ah, but you are forgetting the most important part of solar levitation. The original machine had a base plate of prefabulated amulite, surmounted by a malleable logarithmic casing in such a way that the two main spurving bearings were in a direct line with the panametric fan. The latter consisted simply of six hydrocoptic marzlevanes, so fitted to the ambifacient lunar waneshaft that side fumbling was effectively prevented. The main winding was of the normal lotus-o-deltoid type placed in panendermic semi-boloid slots in the stator, every seventh conductor being connected by a nonreversible tremmie pipe to the differential girdlespring on the "up" end of the grammeters. The whole concept hinges on this point my friend.


raggedy--man

Solar-electric propulsion has already been used in a few satellites. And other forms of solar propulsion exist in theory, like solar sails. Solar energy is the radiation produced by the sun. Visible light, IR, x-rays and gamma rays. I dont think its a contested definition. And solar eclipses have no bearing on solar energy output. The eclipse duration isn't long enough to have an impact that cant be covered by the battery systems currently in place. Nights are way longer than any eclipse and any system in place to cover that will also cover eclipses


CimmerianHydra

TIL solar panels only work during a solar eclipse. The fuck did you smoke before posting this

raggedy--man

The armature in a motor does rotate with the shaft. Without the motor spinning with the axle, there wont be any power output. This part isn't visible due to the motor frame. You just need a see through frame that allows light to pass through and you'll get a non spinny motor assembly


TattooJerry

Even with a coil around the whole thing?

its very useful for education

~~If we connect a DC motor on the other end then we have an alternate form of solar energy conversion method. And it doesn't out GE out of business~~


Koala_eiO

You have a photovoltaic panel that produces DC and your proposal is to use two motors in order to produce a bit less current?


lantech

Then you hook that power output to an electric water pump. Pump water up a hill to a holding pond and release that water downhill to a hydro dam and generate electricity. Use it to power a heating element, produce steam to spin a generator and make electricity again. voila, free electricity all from a solar panel

I was under the impression that these are using photon's momentum to power them. But I realised that using photons for transport is barely possible in space let alone earth


verbose_name

Turn the light off to make it go in reverse.


ArdeDarkie

It's a solar wheel, to be precise. Similar to a water wheel, however it runs on solar rather than water.


stronkreptile

But can we use it to make flour?


codenamed0047

u/savevideobot


BjoerBaer

Thats nice and all, but to produce energy of that rotation you need to put a resistance on one End of it so you can convert it into energy, and that pretty mich ruines the whole flowing part. And I don't think scaling it up would be any mire efficient than a windmill.


jecdrk

It is producing kinetic energy in the form of rotation, but obviously putting a generator and a load on it wouldn't be feasible. It's a desk toy, no one is arguing it's a perpetual motion machine


BjoerBaer

The title sais "motor" not desk toy. So I thought it would be necessery to point that out.


jecdrk

Yeah but it still is technically a levitating solar motor. It takes light energy and turns it into rotation.

Its rotation is evidence enough that power is being output, by your own definition, despite how minuscule that power is. Is it inefficient to the point of being useless? yeah. would a traditional DC motor and a fixed solar panel produce better results? yeah. Is it still a motor? yeah.


zatuchny

You can attach a small fan to it to cool yourself on a hot day


vinayachandran

Yes, in two simple steps - 1. Attach a small fan to it 2. Turn on the AC


lantech

now put the whole thing on a boat and blow the fan at the sails!


slykethephoxenix

Can't you just put a coil around it?


BjoerBaer

Good question: No. It is a solar pannel. If you put a coil around it there wont be any sun on top of it anymore...


BrackWackley

Could you not put a long metal bar through it and put the coil around the metal bar extended past the panels?


slykethephoxenix

That's what I was gonna say. Just extend the bar and make the far end a spinning magnet with coil. Sure it wouldn't be efficient, but it would work!
