This engineer has giant commitment to bolster transition to sustainable energy.. Great Job, Sir!
thank you for saying so - cheers
"...including a lump of cast concrete". Now that right there is the kind of thinking that has us coming back over and over. Thanks mate.
At coral castle that is what Edward did with his model T motor. Sand bagged with cement and used magnets from 7 cars.
If the flywheel doesn’t need to be heavy I just heard about an interesting die-casting material - Polycaprolactone is a nylon-like polymer that softens to an easily formable consistency at around 60°C (140°F). So a heat gun and some makeshift ‘wheel shaped’ mould
lol - I can be brutally practical mate lol
@@ThinkingandTinkering If it works, why not?
On a lump of cast concrete flywheel. That's fine as a flywheel that's greate in certain circumstances, but flywheel mass is not good for wind turbines. Half the time it spins too slow for a given windjust trying to catch up. The other half the time, the flywheel is spinning too fast for a given wind turning your turbine into a fan making wind.
A rotary version using microwave magnets? That is a nice one, would love to see it working!
Cool idea mate and on my mind - cheers
I seen a build simular to this. But it didn't operate like this.
What a way to think outside the box. Your skill set is impressive 👍👍.
wow - Thank you very much!
Thank you sir, really. Thank you. Its channels such as yourself that inspire future engineers, I really am indebted to you
Brilliant! I emediatly thought of 4inline motors, meaning you can do1/4 ofset crank and use 4 bobbins to make 4 phases!
That's a great idea!
Thank you so much for taking the time to make and upload this!!
This is kind of the skill level I have got myself back up to, and I am keen to get one made and working!!
Thank you again.
glad it helped mate and go for it
Good stuff.
Impressive little creation, with huge potential.
I think so too mate - quite a lot could be done with this and the winner here is the sheer simplicity of construction
This is another old but gold video lol.
You need to try this but with smaller magnets and those Lego pneumatic engines
Good stuff. great Video . and I learned something new. ... the bolt just moving while the coil and magnet are stationary. When we were told all the time that one of the two needs to move. but it is the FLUX that needs to be disturbed. COOL. 👌
What about using this concept in reverse? Use a pulsed linear motor to "nudge" a heavier flywheel with magnets around it's perimeter passing by multiple coils...
Was hoping for this today. We are all time travellers. But for most of us, it is a one-way trip.....
Likewise!!
But I can’t quite accept that I weren’t the first comment. :-P
@@matsveritas2055 Let's say you were first today. I cheated by time-traveling to the past.
lol - for sure
That's really cool. Thanks for sharing Robert.
glad you liked it mate
The voltage x amperage is very useful for us poor people who have math skills. Thank you!
Glad it was helpful!
Another useful one I learnt here was the number of electrons in one Coulomb. I knew the charge of one electron was 1.6×10 to the -19, but I hadn’t put two and two together to realise that the practical significance of the inverse i.e. roughly 6×10 to the +18
Looking at the way it operates, the input energy does not seem to be subject to the counterforce of magnetic repulsion the way most generators and alternators are due to Lentz Law. Does that mean less input energy (Or horsepower) is required to operate it? Makes me wonder if this setup wouldn't work well with a Stirling heat motor.
Might be fun to run the Stirling off a plant pot heater in a power outage during the winter.
Morning Rob and Luke, beryllium we use to have washers with it in if they got white power on them over time would double bag them. Who knows where they went too.
landfill probably mate
Hi Robert. Great video. Please stay safe and healthy and take care of yourself and your family members. To all members also. Ttyl my friend. ☺☺☺😇😇😇
cheers and take care yourself
It would be really interesting to compare the efficiency of this one and the one with a magnetic rod (no stationary magnet around the coil)
there is quite a bit of research on this subject mate - just check out google scholar
Thanks for showing how to build incredibility simple generator.
glad you like it mate
Love this!
Could you potentially stack these by using a longer plastic rod with metal sections and multiple magnets/coils?
Amazing how a little bit of trial and error will get your mind thinking about just how easy it is to generate energy. Fair enough you only got a little by spinning by hand but many of these on a large blade section will do surprisingly well at charging batteries freely.
I would think so mate - the thing about reluctance devices is they work well at high speeds
Great idea👍
Thank you! Cheers!
@@ThinkingandTinkering it reminds me that it's the opposite of a solenoid and wave movement would power it instead of being attached to a wheel moving up and down.
All of the "for free" videos on UA-cam do not take into account the CNC machines. I appreciate the focus on finding already built parts and just using a drill and saw
Robert, The curiosity to see the higher voltage at a fixed RPM to better know the electrical generation efficiency of your linear metal rod motion magnetic circuit path design has hold of me. If I were to replicate your design, but instead of driving the pulley with a variable speed human finger, instead use a rubber sanding tube wheel attached to a electric hand drill placed against the metal pulley's outer edge smooth surface to drive the metal rode reciprocation faster in hope to measure the steady voltage increase at a known and, consistent pulley RPM thus discovering the efficiency of magnetic reluctance path copper electron movement voltage pressure is an intriguing thought to replicate to quantify. Robert, so interesting of a linear design concept that combines a magnetic field lines circuit, and copper coil electric generation !
I'd be more interested in using this without the rotary part as a way of harvesting energy from steps. The piezoelectric generators need to slightly crack every time you step on them and it's not so easy or cheap to scale up. With these you could have stepping stones that might be somewhat uncomfortable to some people to walk on but that generate significant energy.
Maybe some sort of mechanism that lets a spring fire it in and out really fast before latching back on to the stepping stone, or an elastic one like a wind-up car
fascinating version of the Kromrey generator! or More commonly known G-field. Patent number USP #3,374,376 But without brushes! nice!
cheers mate
In feb of 2016 you have made a rotating switched reluctance motor that can be easy modified to an switched reluctance generator
cheers
Nice video such a good teacher!! take a look at gérard morin hyperdrive !
I think that this generation method would lend itself well to the wind ribbon method of collecting wind energy.
With this type of generator, is there any reluctance or back EMF force against the bolt moving in and out?
Nice thinking.
Thank you! Cheers!
I can imagine that multiplying the generation cores by maybe 8 in the configuration of an old rotary. Airplane engine then wired together . you can probably use a mtn. Bike Wheel as a jig to mount the whole assembly . one question though are the poles oriented the same in a speaker magnet as they are in a microwave magnet or would one be better suited then the other
I think they are mate - basically north/south on opposing faces - but I am not sure and will have to check
Robert...what about making a multi rotor homopolar generator, and a DC/DC converter to get the voltage up to usable? No windings. Can be made from steel discs and magnets ( brake rotors etc ). Wouldn't be good for a HAWT without a mechanical linkage, but for a VAWT would be easy. You could even put a big cap inline to smooth things out.
FYI, the material used for the rotor appears to matter in some way. Iron is apparently better than copper, for example. I haven't studied this, but I've heard the word "reluctance" used.
Personally, I think homopolar generators are a wonderfully unstudied area.
Wow I can see that this generator can be expanded in many ways. Have you tried to use computer fan motors to generate a voltage? cheers DVD:)
Yes, mate I have and done a few vids on it
1) What is nice about this is the mass of the flywheel, the piston, and piston rod can be minimized to only that which is needed. But then again, one ends up adding mass when they goto balance the weight Of the piston and piston rod. As to a lump of cast concrete flywheel. That's fine as a flywheel that's greate in certain circumstances, but flywheel mass is not good for wind turbines. Half the time it spins too slow for a given windjust trying to catch up. The other half the time, the flywheel is spinning too fast for a given wind turning your turbine into a fan making wind.
2. Don't use an aluminum ring inside the bobin. Use nylon or something nonconductive. A conductive ring acts like a shorted single turn coil on a transformer. It's just going to disipate heat from circular eddy currents. Drop a magnet inside a copper pipe to see how much energy may be lost.
Some videos ago you had made a magnetically controlled motor with this clever system you can made a linear switched reluctance generator
cheers
Would running a single rod through multiple coils generate more electricity or would it simply cancel one another out?
If it cancels, you could always extend the rod using plastic or wood couplers so that each coil and rod setup are independent of each other.
I think you would need metal-plastic-metal-plastic as an arrangement mate
Can we make one big enough to induce flux cavitation? What would be the consequences?
I have no idea what that is mate - want to expand?
Can you complete the path with a fast ass switch.?.connecting the left n right pieces of steel on the magnet... Or it's gotta be a a certain size related tube?......I work at a dump ..they got much large blower etc type motors .....seems like ya could just take the guts outa em n solder a mile of those coils wrapped in steel harnessed magnets and oscillate slide a steel tube through em with no wheel?...or can ya shake steel in oil a billion times a moment back in forth the same way? I don't know what happens to the poles in magnet oil...but steel seems like it shouldn't matter...idk ..this is my fave one ya done but they are all Bangers..:)thanks
I think you can slap a magnet on the end of that rod for a boost!
But then the generator would not be a switched reluctance generator anymore
Switched reluctance motors are getting interest for their independence from magnet producing countries.
@6:41 you've made a little song there!
it did have a rhythm didn't it lol
You to. Thank you. ☺☺☺😇😇😇
Hi Robert, This could be a good starting point for a wind compressor? I'm off grid and currently "waste" about 9kwh a month of my solar power to pump air through my sewage treatment plant (timer only runs it for 15mins per hour) so potentially people could save upto 40kwh per month by replacing the electric air pump with a wind pump. I've watched some Armish videos, they use wind powered air compressors to power all sorts of tools, even washing machines obviously they need higher pressure, the treatment plants just need air bubbled though the water to maintain the oxegen levels and to provide agitation.
Are you using the sewage to make fuel?
@@MAGnetICus_Attractus Sadly no! I do have to waste Diesel fuel in the generator when the Sun fails to show up! although the UK Sun is surprisingly reliable.
I suppose it could mate - you can see compressors powered by wind as a kind of battery system - the compressed air taking the place of the battery as an energy store
whats a mosfet in circular array on a disc turbine as brushes make?
I dunno mate
@@ThinkingandTinkering could this be used 4 pulsating Direct current
Hi a linear solenoid can it be a generator 🤔
please sir... can I have some more?
you forgot to mention where the wires are connected
sorry about that mate - there is nothing complicated the output is straight from the end wires of the coil winding
Is it possible to make a DC generator by having a second magnet/coil and rod that pushed into it when the first gets withdrawn? Or would that simply “double” the outputs? Seems to me that you’re not maximizing the potential here, even though the voltage and current is small from one half like this.
I am definitely not maximising it mate - this is really a proof of concept model - tons of improvements to make I would guess and I think your suggestion is great though it wouldn't produce DC
@@ThinkingandTinkering you’ll show us how to increase the output in upcoming videos, I hope?
the usual way to “double” the outputs is to add a second coil to use the unused magnetic pole(s), oc there's also the original designed in 'transformer' reinduction options at the same time too
Quite interesting design. Could be used in some scenarios where classic designs are not practical.
I think i saw something like this is the sterling generator from nasa for the deep space probes.
absolutely agree mate
I thought that used a moving magnet?
What about magnet motor?
Is this more electrically efficient than a 'pancake' generator? There must be more friction though?
I have no idea mate but I doubt it - I didn't do it for efficiency - it's made for ease and there will be an efficiency cost to that that's for sure
this somthing for the beach some floating stuff and then whit the wave it moves
I like that mate - anything where there is straight linear motion - nice one
Reminds me of the windswimmer, could also be used as a waterswimmer
With a CVT (electronically controlled) you can obtain pure 50/60 hz and power at disposal
Don’t know what That is (about to look it up), but that possibly sounds like an inexpensive way to turn and inverter into a sinewave inverter for sensitive equipment like laptops
cheers mate
nice.VeryNotUsed,TheseSwitchedReluctanceDevices.
no they aren't but they are awesome have lots of benefits and are the subject of a lot of academic research
What's the windmill on a stick called? They can be brought on beaches and from garden centers.
It's like a square sheet with the corners pinned into the middle.
Anyone know Please?
most I have seen are called a toy windmill.
Pin wheels or pin mills
Rob has done a few vids on these.
@@flytrapjohn thank you. I have seen these videos also. They are equally entertaining.
I'm curious as to the name of the rotary blade set up. Not the construct it's self.
Pin wheel means nothing. It is a title with empty context.
I don't think there is a specific name mate - I have seen toy windmill like Ed said and pin wheel like mittens suggested - but not much else
Easy as falling off a log. That's great.
that is an interesting bit of engineering cod the magnets pull the rod throw the Pip on the same way a mag lenth pulls a tram down a pipe .those collapsing sever geniting magnet as it travel the crueller course as a stingier. peace of steel Or joined Together by nonconducting elements . then an engineered circular. generator Driven by a set of repulsing magnets A repeating driving in a cercal & :- {passing on it journey trough a stationary coils such as you have dementated } This powered by switching coils driving the singular slug Of Steel. Or circler slug's of steel equally spaced. , steel being the magnetic interface , i suppose it the classist one can get to perpetual population one could get . could the coils produce sufficient over unity to drive the switching drive coils ? It would be interesting to find, out coils we now can drive along a slug of steel forward in a continua's loop as in selenides do when pushing a starter in to action. but can it when passing past a magnetism colt of wire sow it to such an existent it Avennchaly stalls the drive. ? if not can the drive cols diver sufficient thrust ti pas a grater field of magnetised power producing coils? Just as when we pas a magnet down a coper pipe it slows it's descent. dos the cols failed do the sane . if not you could have a new form of generation in your hands. parps the first tentative step's towards an electro magnetic generator . it is quit an interesting principal you have demonstrated. it need some research i think i suppose a system using compress air could used the the rotation of such a devise contend in a circular pipe doing the job of the salmonids just a different approach & idea.
It's a reciprocating combobulator :-D
discombobulator! ^_~
Combobulate (Verb) To put together in a somewhat mysterious manner. To bring something out of a state of confusion or disarray. To manufacture by some unusual or novel means. Antonym: discombobulate.
Definition. Combobulator (Noun) Any contraption the combobulates. Usually a far-flung contraption usually designed to perform a mysterious process in order to manufacture an amazing or highly unusual product or outcome.
lol - it works even better when you connect the doohicky to the thingumabob mate - or so I have heard lol
@@ThinkingandTinkering everyone forgets the doohicky & thingumabob so their hard to get, and cant order them on line O.O
Lenz law will still apply
yes - of course it will
bruhhhh... aint no way lol... my face right now. thanks boss. Ill be making one now. but now im thinking a way to combine.
awesome mate - do a vid! I would love to see it
Reluctance is inductances weird cousin lol
yeah - I know eh lol
you just built teslas earthquake machine!
I thought Teslas earthquake machine was a mechanical oscillator?
@@ThinkingandTinkering your setup is electro-mechanical
What's wrong with your videos...
They are addicting... And I stay up to late..... 🤣🤣🤣🤣🤣🤣🤣
Rod in Rod out
Wallah you have electricity
like magic lol
Or adult fun time?
I’m sorry but I think that you generator aren’t a switched reluctance because it’s using a magnet and no electronic.
You can made a linear single phase generator with a coil electromagnet two mosfet transistor two diodes one condenser and a optical switch and one arduino to control the switching of the mosfet transistors
actually jgb can make & video a version of 'a linear single phase generator with a' ....
wouldn't want to wait for everyone else to make 'the thing' so you dont have to right....
it's like nothing in the macro scale didn't already exist that these micro devices took their names from right ^_~
* 'and no electronics' = The field-effect transistor is a type of transistor that uses an electric field to control the flow of current.,
A diode is a two-terminal electronic component that conducts current primarily in one direction; it has low resistance in one direction, and high resistance in the other.,
An accumulator is an energy storage device: a device which accepts energy, stores energy, and releases energy as needed. Some accumulators accept energy at a low rate (low power) over a long time interval and deliver the energy at a high rate (high power) over a short time interval.
switching the flux along different paths is what switched reluctance is mate - you can do it electronically or mechanically - or indeed a hybrid - but the core of what switched reluctance is - is changing the path the flux field takes through the magnetic circuit
