Solar Energy Motor / 12 Sided Mendocino - Motor 

It's beautiful, I was looking for the worlds largest Mendocino motor and found this video. Thanks for showing it.

No doubt one of the finest models of a mendocino motor ever built ! Does it generate electricity ? I have visited Germany several times in the last few years and am always impressed by resourcefulness of the people and the quality of the craftsmanship in the things that are designed, manufactured and sold in Germany. Great job , well done .

I can't resist the temptation to do some analysis of this thing. @ 0:49 we have 36 individual panels that are 30x55 mm in size, each with a power output of 0.5V*400mA = 0.2watts, but ONLY when you have ideal conditions: the sun shining directly on the panel perpendicular to each panel at the equator. Otherwise the power of the cell quickly falls off as the cosine of the incident angle and the time of year when solar insolation is reduced. The claim for each cell's power output of 0.2 watts assumes about a 12% efficiency, not out of line with a low cost solar cell and assuming a solar insolation of 1kW/m^2 (generally considered to be the value to use). When a cell is angled to the sunlight, then its output power drops by the cosine of the incident angle. Hit it head-on, and cos(0) = 1. Hit it at a 45 degree angle, and cos(45) = 0.707. Hit it at a 90 degree angle, and cos(90) = 0. When the cells rotate to the shady side of this 12-sided "cylinder," it produces no power at all. Thus, a row of cells receives power only during half of a complete revolution; the other half of the rotation produces no power at all because no light hits it. This reduces the efficiency of a row of cells by a factor of two. To calculate the total power during the 180 degree rotation when light hits a row of cells, you need to perform a simple integral of the cosine of the angle between +/- 90 degrees, which calculates out to (-1 + sin(x)) for x = -90 and +90 degrees, which is equal to 1. But because the other 180 degrees of rotation results in no power output, the AVERAGE power output for a complete 360 degree rotation s the integral term (=1) divided by 2, or 1/2. Because we have 3 cells lined up side-by-side, the maximum power hitting any one row of cells is 0.2W * 3 = 0.6W. As this row of cells makes a complete 360 rotation, per the above calculation, the total power it produces per revolution is 1/2*0.6 watt = 0.3 watts. There are 12 such rows, so the total maximum power going into this motor is 0.3W *12 = 3.6 watts. Note that this is 1/2 the power that one would assume by multiplying the total number of cells by the power output of each cell (36 * 0.2W = 7.2W). Assuming no losses from the output of the cells, the motor can deliver no more than 3.6 watts of mechanical power, or about 5 milli-horsepower. I.e., don't expect to see it powering your next power tool. Let's now consider the physical size of this contraption. I am about to make some educated guesses here since I don't have actual motor dimensions. The panels are each 55mm wide, and there are 3 of them. There is space between them, so let's assume that the 12-sided "cylinder" is 65mm * 3 = 200mm wide. The circumference of the drum can be roughly assumed to be (30+10)mm*12 = 480mm. This is a circle approximately 480/pi = 150 mm in diameter. If I shine a light directly overhead on this cylinder that is 150mm in diameter and 200 mm wide, it will cast a shadow that is 150 mm * 200 mm = 0.030 m^2 in area on the ground below it. What if I now pitched this solar-powered motor and replaced it with an array of cells laying flat on the ground (i.e., a typical solar cell array) with an area the size of the motor's shadow, 0.030 square meters and with an efficiency of 12% (same as the assumed efficiency of the motor's cells)? It's power output would be about 0.030 * 120, or 3.6 watts. Compare the two calculations, and you see that they are identical. In fact, they SHOULD be identical because this rotating drum's X-Y surface area that is illuminated by the sun, MUST be the exact same X-Y surface area as just a conventional flat solar array. I.e, there is absolutely NO GAIN to be had this motor and a flat solar panel with the same dimensions as the drum's X-Y footprint! In fairness to the motor's design, the driving force behind putting the cells on the motor itself is so that they do not require power wires going into the motor which would entail complicated brushes and the like. The motor is "self-contained." You can place it anywhere and it will turn (assuming some light source is available). That is why the cells are on the motor, not on the frame that holds the motor in place. *The motor can supply no more power than the solar cells can deliver to it.* If you now advocate using mirrors to cast more light on the backside of the motor to increase its received power, I then reply in return, "okay, then give me the same surface area of your new mirrors and let me add that to my flat solar panels, too!" You take real estate to send more light to the rotating motor; I take that same real estate and add it into my flat solar cells. No net gain! What is the purpose of the motor, solely to rotate, or to deliver torque? How much torque can the motor deliver with a candle as its power source? A: the same amount of power that is contained in the candle light. I.e., virtually zero. While beautifully constructed, the motor's main feature is friction-less bearings, not power conversion (light to mechanical power (torque)). Some commenters here have themselves convinced that this thing can be scaled up and used to power a 100- ton freight train on a winter's night. Wrong! Remember this: *you will NEVER get more power OUT of anything than the power that goes IN to it.* It's called conservation of energy. If you believe otherwise, then you also believe in perpetual motion machines. Good luck with that.

Amazingly incredible great presentation brilliant great work

10/10 for documentation.

I've always wanted to see this on a much larger scale and have been wondering why no one on the internet has done it yet.

Schönes Stück Technik, genial

Very nice. Love the way you made your video.

thank you for this video

This is wicked. Awesome presentation.

Revolution is already there and takes time. additionally for the zero-energy-searchings (ahain...): if this machine would be more efficient than just the regular solar cells it would hurt law of physikc. Its just an awesome transformation of electrical energy in rotary energy (the motor itself). its just some different concepts covered in one machine. But this also shows where future technoogies are leading too. Its not about getting ore enrgy than befor, its about having perfect energy-transmission between different forms of energy. this one shows how to translate electrical to solar (LED), solar to electrical (Solar-cells) and electrical to motion (the motor itself (what is the real message of the video)). You dont need to have zero-point energy if you are able to convert all forms of energy nearly without any loose (unwanted energy transmissions in energy-forms that we can handle that well (temperature)). An den Erbauer: Super Ingenieurs-Leistung!! Arbeite selber im Labor für Analog- und Opto-Elektronik :)

bravo ...Nikola..!!!!

Das Video ist eeeecht gut gemacht!!! Gratulation!

starkes Video!

Realmente interesante..Great Video, Thank you for sharing..!

Schaut super aus - nach dem Energie Erhaltungssatz also genau dass was man erwartet ('~') .

sau geil !!!

Super Idee

Wow cool😎

А без света ни туды и ни сюды... "Бог есть свет и нет в нем ни какой тьмы" Библия

What took longer? making the motor, or the video?

great model, so the next one will have horizontal magnetical suspension too ?

Sure, ill bett you could really power a useful load w that, this is basically a rotary version of those toys that rock back and forth in sunlight.

It would be cool to see it run from a jar filled with fireflies. :)

brilliant design, beautiful motor, but its nto free energy if there has to be sun getting it to work

Very nice object and the video is beautifuly made with good music. Thank you.

Hi. Kann man die Rotation und die Energie aus den Solarzellen zur Elektrizitäsgewinnung nutzbar machen und ist diese Energieausbeute dann höher als bei gleichen Solarzellen die direkt dem gleichen Licht ausgesetzt sind ( also Energieeffizienter ) ? Auf jeden Fall ein sehr schönes Gerät, super Arbeit

Why do you need a sensor? The key of mendocino motor is that it works automatically

But why. Basically how it works is "Light -> Electricity -> Motion", then what's the next? Motion energy to what?

Como ventilador funcionaria bien.

We have to respect to Mr John Bedini and Mr Cole for the construction of rotor. Is that right?

What is the practical uses of this motor?

Thank you for this video can i charge my cellphone and watching youtube etc.

Cool idea. a lots of potential. Wireless phone charger? Also gonna be cool looking back at this in a couple years.

Mount on the bottom of the mirror =)

this mendocino motor can act as generator prime mover!

Very good, congratulations! How to adapt a Dynamo to generate electricity?

Stellt man einen 3D Spiegel "mirror" hinter das Model so bekommt der Motor mehr Energie und dreht sich auch viel schneller :)

Large demo of current expertize. Still, : flea power!!

cooool wu savd mi

At present, this is a novelty; it has a very low power output. Some motors even rotate in the shine of a tealight. Mostly the motor is used as technical decoration or as functional model.

😯👍

It's more effective if you use all the solar panels in direct sun light and moves a conventional motor

Does it carry a load? Can it spin a generator? Otherwise what's the purpose?

I have some questions and ideas in regards to adaptations and interesting uses of the Mendicino motor, if you wanna collab, or just hear about it, and help, please let me know, AWESOME Design !!!

good work. what do you think in a box with no air ( vacum )

Why u do not extend the levitated part to connect to a motor and produce power? Wonder how much would that be.

Respekt macht nen echt guten eindruck . wie viel Energie kann man damit erzeugen ?

Hallo Wolfram: Wow, bin absolut fasziniert... Eine Wissensfrage: Wenn ich die Sequenz ab 2:00 richtig interpretiere, betreibt der Motor die LEDs. Wenn doch der Motor (NACH einer wie auch immer gearteten Anfangsenergie) die LEDs betreibt und diese Energie als einzige Lichtquelle wiederum den Motor, ist das dann nicht ein Perpetuum mobile? Oder geht irgendwann der Lorentzkraft "der Saft" aus und der Motor wird langsamer, das Licht schwächer und der Motor kommt zum Stillstand? Noch ne zweite Frage: Ist dein Motor der einzige 12-flächige? Wenn ja, was ist der Vorteil gegenüber den 4- und 8-flächigen Motoren? Schon mal über eine Vermarktung nachgedacht?

I can only see how one end is held up, how is the other end held up?

very funny ; what's the point of solar panel mount on motor directly ? that would impact irradiation and panel efficiency, your panel was no function in half. why can't design panel and motor two system?

So can you put a couple of rotors at each end with small coils to generate electricity. Maybe combine this with the easy spin motor.

Це МОДЕЛЬ ЕЛЕКТРИЧНОГО МОТОРУ. Немає сенсу подавати це під музику, типу існування всесвіту залежить від цього. І якби то було лише це відео, то вже нехай, але ж так по всюду: "О дивіться, я зробив іграшку для ванної із запальнічки і вібратора, і поставлю такий саундрек до відео, щоб ні в кого не виникло сумніву, що з її допомогою я можу вмикати і вимикати Судний День, коли мені того хочеться!" Я, звісно вибачаюсь, якщо кого образив, але реально вже дістало.

This is like suddenly waking up of a bad dream and finding the real light. Hey Where can I buy them or maybe import them here to my country?

WOW!! this tube is simply mind-blowing, as it shows a 12 sided Mendocino Motor producing 1,5 watt powered by a LED 0,8 Watt this is a technology that will make the future brighter. That's why I share it on my favorite Facebook group, "Future World."

where can I order?

How much difference does it make if rotational axis was vertical? Has it been tried?

Огонь. Интересно на что больше идет энергии, на само вращение или на работу датчика оборотов )

Sagen Sie mir drei Solarzellen auf der einen Seite des Rotors parallel oder sequentiell verbunden? Und was ist der Grund für eine solche Verbindung? Скажите, три фотоэлемента на одной грани ротора соединены параллельно или последовательно? И чем обусловлено такое соединение?

So You have got 36 panells which can produce 0,4A and 0,5V so each is giving 0,2W multiply by 36 items we have 7,2W. Question is how much power You can get above that by Your machine? If it is lower than 7,2W its just a toy then.

Super..er dreht sich. Aber hat er auch die Kraft, etwas anderes, ausser sich selbst, anzutreiben? Durch die schwebende Lagerung gibt es keinen nennenswerten Widerstand. Jedoch wird er schon in Kugellagern nicht mehr laufen. Ist, meiner Meinung nach, nur Spielerei.

"schwebt" der Motor durch die Rundmagnete, oder schaut das nur so aus?

add leds :D

¿De donde eres? Mendoza, Argentina. were do you from????????

3:10 MUSIC PLEASE

is it only fancy or can those motors drive something at the end ? or generate ....

where can i bye this

Yes I get it makes power but the cells alone make very little power nothing close in the range of even 1 kw of power or more hence why rpm's are very important in its spin

Kleiner Tipp für die Lagerung: Auch über Magnete links / rechts von unf auf der Welle machen, sodass es wirklich reibungslos - bis auf den Luftwiderstand - läuft. ... und ein Designfehler hat dieses Konzept: die Solarzellen müssten nicht rotieren, um die benötigte Energie zu liefern - also: drahtlos übertragen von außerhalb, also Spule(n) in in den Sockel, Magnete zentraler auf die Drehachse, und die Höhe der Achse anpassen.

🤫 👀 👍

ماذا المكونات

What is the rpm's for it can u hook a magnet alternator to it to actually make power?

how much ?

Too grand music. so fun.

okey, now where can this be used with this average performance ?

How well would it run in a Vacume ????

das mag ja auch klappen-wirklich es funktioniert-entscheidend ist der wirkungsgrad-ähnlich wie beim wasser das mit der ukw hz getrennt wird und brennt-dazu ist 1kw sendeleistung nötig und was komm dabei rüber?-na klar arbeitet dein Motor er ist aber sehr wahrscheinlich leicht zu stoppen.lg das hätte ich fast vergessen die musik ist sehr gut danke und das ganze noch einmal auf englisch.This may well also flaps really it works-what is decisive is the efficiency-similar to the water with the FM hz is disconnected and burns-1kw transmitter power is necessary and what will come over?-na clear your engine works but it is very likely to stop easily.lg i almost forgot the music is very well, thank you and the whole once more in English.

Amazing

Will this thing generate electricity? A Stirling engine will and the power produced by a large Stirlings will actually drive machines.

For the "haters" out there... we always work to develop the "concept" and make it work. Not work to discredit the concept. Or you can continue to let yourself be screwed by the upper 1% like cattle as usual lol

Pity it can't do anything useful, like turn anything.

use this for generate energy? put some DC motor and generate?

I want to buy this Where can I find it

Is the light pushing on the solar panels causing it to rotate?

Hallo, also ich muss sagen, eine sehr schöne Arbeit gefällt mir sehr, könntest du mir sagen was das Material gekoste hat? und eventuell die Pläne mir senden? möchte gerne deinen Motor nachbauen . Nochmals fielen Dankt für deine schöne Arbeit und Präsentation.

que pasa aca!

Sure it works and it's neat but it has no power.

free energy motor?

This is just a toy! Motors gives tourk. Any tourk?

3:11 song plz!!!!!

like but how much power

Sun light is 126.22 hertz have you tried using different Hertz frequencies to generate a charge?

В идеале его поместить В вакуум.

what good is this? it is a free source of energy, do you think the way things are with our electric companies that they will allow us to get electricity for free?????? good luck with with that ?

Всем, кого интересуют альтернативные источники энергии - рекомендую: Магниты неодимовые - ali.pub/cipjz

Мотор мудачино работает от свечки

Maybe if you give it a fancier name it will produce more power LOL

But does not work in the actual sun. It would disintegrate :)
