Wheels, Bombs, and Perpetual Motion Machines

"It worked until the city experienced a power cut."😂😂😂

You should make an episode that's a little more unsettling than the rest and call it "Things you might not want to know"

Inventor: hey everyone I just made a perpetual motion device that puts out more power then it takes in.
Scientist: He's got a bomb!
Soon after the words "perpetual motion" are also banned from airports.

I prefer to define the term "perpetual motion machine" as "a kinetic sculpture with a very cleverly hidden source of energy."

[MichaelJenkins]

The distinction between "pah-tent" and "pay-tent" was duly noted and deeply appreciated by this American. Thanks for an informative video!

In this house we obey the laws of thermodynamics!

My partner works at the UK Intellectual Property Office and apparently they have a room somewhere with all the models sent in by perpetual motion machine inventors who are insistant that they do work. These are usually sent in the post without proper labelling and also cause a bomb scare every now and then

I made a perpetual motion machine once. Unfortunately I left it in the future while testing my time machine.

For those just arriving from the notifications and wondering why it looks like other people were already here: the Royal Institution tends to publish their videos in the morning, so some people have come over from their channel. :)

Nice effect at the end there. I did not expect that.

“Until there was a city-wide power cut.”
*glove snaps*
Great timing and execution.

"It would keep spinning forever, you just wouldn't be able to get any useful work out of it." No need for a true vacuum, we have plenty of politicians who can manage that right here.

[maxximumb]

That couldn't be a bomb, it didn't look like a clock.

Has anyone else noticed how Tom marks his videos in the thumbnail? "Things you may not know" videos always have a red bar on the left, and "Amazing Places" videos always have a bar on top, I just thought it was cool.

I used to think about this concept back in like second grade. My theory was put a motor to a generator that in turn powered the motor. To start the machine you need to use a large capacity battery to get the motor going fast enough where the generator would be able to power the motor. And to get energy just slap a few fan blades to the motor so it makes a breeze and then convert that to energy. I know this would not work but it fascinated me as a child

Tom Scott's is the most pleasant comment section to have discussions in. In all of YouTube.
Great job in building such an intelligent, educated and amicable community!

[vladtepes]

you didn't have to spin that wheel to know it wouldn't work. the designer knew what he was doing when he put that stop sign in its centre.

[MeowMeowDeathRay]

"US patent office" and "UK patent office"... That's cute.

"After a few seconds youve got a bomb"

Pressure cooker motto

[SpektralJo]

It is really surprising how many people actually belive in working perpetual motion machines
