Professor Eric Laithwaite: Motors Big and Small - 1971

blogs.imperial.ac.uk/videoarc...
Professor Eric Laithwaite (1921-1997) of Imperial College London demonstrates the difference between magnetic and electro-magnetic motors. Examples futuristic - include minute pump that can fit inside human tissue and a huge test rig to help develop high speed vehicles driven by a linear motor.
This is one of a series of 16mm colour films made for schools. They were all made in Eric Laithwaite's "Heavy Electrical Laboratory" in the Electrical Engineering Department at Imperial College London.

Great video! I wish I had teachers like this. And that voice.... so clear, authoritative, yet not intimidating.He must have been a natural teacher.

[@andthetruthis1640]

felt like I studied under him! What a professor to have! Thanks for the video

[@user-wt2yz4le7c]

A clear explanation and excellent examples. Continue like this

Many thanks!

I wish everything in life will be like the scientist is showing us he is truly a genius!!!!!!

[@davidmyersretiredaerospace8038]

Nice man very similar to my old professor my dad.

[@balance2935]

Very glad he planted that seed of knowledge I mean. At least he had a chance to give his dream to others.

I have only watched 2 videos if teachers taught like this life would be easier. But then again some people back in school wouldnt of kept up.

That three-phase linear motor is pretty cool

This is quality video, not what we have today, finding such films in an avalanche of shit these days is almost impossible. In addition, nowadays in education, instead of respecting knowledge, it is more important to learn how emotions have an impact on the world ...

With relation to the cylinder rolling the opposite way to the flat plate, on the moving magnetic flow. It's like having a hoop or cylinder on a long carpet . Then taking one end of that carpet and quickly pulling it out from underneath the cylinder ,giving the hoop a revolving force which sends it the opposite way to the carpet

I love this.

That was 1971. Now 43 years later, we still use the over 100 years old combustion engine. Something is seriously wrong in this world.

[@RonJohn63]

The diesel & gasoline engines of 2015 are *radically* more efficient than those of 1904. *R-A-D-I-C-A-L-L-Y*. Anyway, 40 years later we also don't have flying cars and practical supersonic passenger airliners. Why? Chemistry, physics & STP. Some types of heat engine are more efficient than the ICE, but that engine must fit into the hood/bonnet and fuel under the trunk/boot while being conveniently fillable even by those barely able to string three coherent words together, much less control 1500 kg of high-speed death. So... of all the wrongs in this world, "still using ICE" is the least wrong.

***** /I don't believe - I know that is a huge difference./ That's exactly what Kennedy Assassination and "9/11 Truther" conspiracy theorists say.

[@eXtremeDR]

RonJohn63 But they don't know - they believe because they can not verify their believe. What some claim to be a conspiracy, is none - it's the system we are all living in. And there are reasons why it has to be that way. The advantage of physical existing motors/generators is - you can build your own - no need to believe and relay on others.

Eric Laithwaite a truly remarkable man made machines that worked for ICI and so was the man. Them that can do them that cannot teach. The paper only profs slammed him because he wanted to levitate a gyro pair that never stopped. There are a phew gyro motors on KZbin and if you spin a permanent magnet on a spinning top over a flat large permanent magnet it does levitate and there also videos on KZbin showing that. he did make his double gyro but with Mechano at home because he lost his lab and this machine in this video the Japanese turned into a train the British Government who should of funded that after this was shown changed all schools to Comprehensive from Grammar and Britain's inventors go unheard and un funded ever since.

Only the beginning......

[@ruanjiayang]

In the film, Is the "magnetic motor" the so called Switched Reluctance Motor nowadays?

[@audiodood]

I think its a synchronous motor

[@stevengoelzer]

A tank of water next to an open and uncovered ac current? What could go wrong?

[@bad71hd]

They need to show these to third graders if they want to change the world and free energy production Galore

[@-41337]

too bad he didn't get to realize his dream of anti gravity. i wonder why? any forces working against him?

[@Pinkielover]

rip

[@youngrogsoprano5343]

Honestly, it is screaming Nicolai Tesla. As in the work that was taken by the Feds as soon as possible following the death of his Body. I am not saying that it was not right. I am sharing a gut feeling. Either way, I am grateful for the weird things that electricity does. I am happy to be an electrician. I love the fact that I aced the class. Now I will start the video over because of my incessant need to make it about me. 😤💯🖤😤💯🖤❤️😤🖤🖤😤🙇🙇😤Just listen to Deftones. Duh. I am a Californian exactly like the SNL sketch

[@lordfantastic]

why the heck do we still use gas??? what is the wrong with the world ?
