Not only does it have a wonderful history of failed inventions, schemes, scammers and blaggards it also has the potential to provide free and clean energy forever.

I find it all very intriguing, what with Len's law now having been overcome, its looking like a real possibility?

Anyone else into this, tell me what you know!

I'd like to tell you but I've signed an NDA.

Mr Nutt, I am worried that you are losing the attributes of your namesake. What are you going on about? Do you mean Lenz's Law? Conservation of momentum? Overcome? What? Explain with links..

yes, I mean't Lenz

here you go:

I have a perpetual motion device that works in my garage. Trouble is I'm scared I'll get bumped off if it goes public. You can buy it off me if you like for 10 million quid.

how do you stop it? what if the speed keeps increasing the more load you put on it?

Science is the art of the soluble, MrNutt, according to Peter Medawar. It's a great quote, because it helps you discriminate between truly interesting and important problems in science, and ones that just appear interesting on the surface. Perpetual motion is an example of the latter, it's barely even that tbh. Origin of life studies are another example - a minority of brilliant work but a majority of pish that lacks the art of the soluble.

i think he doubts it because it violates many of the laws of physics.
FWIW I am with him on this one

By definition, of course there is. Physics means the study of how everything works.

It may well be the case that we are only aware of part of it.

Question: if perpetual motion is possible, aren't we doomed to a world of rapidly increasing temperatures and general suchnsuch? As in, the motion/ slowing it causes heat; the motion never stops, so it's a never-ending source of heat. Do it on a big enough scale and watch it all go pear-shaped...

build yourself a hydraulic ram pump (thanks Montgolfier brothers), ok, it needs running water but that can be had free, they can go forever

It'll keep heating up until it hits 2,147,483,647. Then it'll overflow and jump to -2,147,483,648.

The Clarendon Dry Pile?

As an alternative to watching paint dry there's the pitch drop experiment

As a chappy working in engineering in a university I've so far signed 3 NDA's to look at (quite well qualified people's) ideas for perpetual motion machines in the last 2 years. All of which could be blown out o the water in 5 mins with some quick calculations and common sense. I don't see it happening any time soon.

When I was 7 or 8 I went to bed with a pad and pencil and invented a perpetual motion vehicle (big metal object at the front and bloody great magnet at the back) and went to sleep happy in the knowledge I had solved a major world problem so easily. I woke up in the morning, took one look at my sketch and realised I was an imbecile and would have to satisfy myself with a life of mediocrity. Probably one of the most depressing moments of my life.

I was once at a technical conference in Edinburgh Uni where an engineering student stood up and asked if there were better ways of recovering energy in a vehicle (than solar panels on the roof) "such as placing a large wind turbine on the roof". There was a large intake of breath and a the mutterings of dissappointment spread throughout the room. The student, clearly aware of the growing unrest around him said "I'm just one man in one minute and I can come up with something like that, if lots of us think about it...". I'm amazed the speaker didn't even break into a grin, he carried on very professionally.

Weirdly enough I went through the same thing with a MAGLEV train I'd designed. I thought I was a genius. The Germans and the Japanese thought I was forty years too late.

If you put a fan on the rot of a car, will it recovery energy on a treadmill?

Actually, there is something to think about here. Perpetual motion is clearly nonsensical since where does the extra energy come from? Even if you had perfect bearings in a vacuum and made a machine spin indefinitely, the moment you try and draw any work from it it'll slow down.

The real question is about converting energy from somewhere that's either a) not obvious b) currently unknown or c) readily available and free/really cheap.

Nuclear fusion would come under c) but would have been in categories a) and b) 100 years ago.

I'm sure the answer is magnets. 😀

Good luck with that! Been there, done that. Can't take the disappointment of going down that road again. 😉

What about a piezoelectric motor sat on a car engine? To capture the wasted vibrational energy of the car.
You could then use the motor to power a little smiley face that lights up on the dashboard. It might quieten down the car a bit too.

What if you mount the fan perpendicularly to the direction of motion?

Yup, I believe that's currently being researched/applied but the energy available is fairly small and hard to get.

MMM... sat in a traffic jam, ickle motor absorbing all that energy from vibration so the car can smile at you, by turns doubling, tripling, quadrupling your frustration - it'll never catch on 🙂

Once you have an electric/petrol hybrid there are all sorts of opportunities for scavenging electrical energy besides braking.

My ideas are electromagnetic damping in the shocks, a steam turbine driven off the rad (Stirling engine is it?) and a generator attached to an exhaust turbine. That's my fave idea, since we already make turbos nice and easily. Attach some magnets to the fan and bosh.

Mine is clevererer. A boiler that is kept boiling by electric elements that are powered by a steam turbine driven by the boiler.

I'm just thinking where to get an endless supply of water from and where magnets fit in to all this. But once I've worked out those details, my world-beating device is ready to go.

Do I win £5?

My ideas are electromagnetic damping in the shocks,
Exists, tiny amounts of energy are harvestable on a normal vehicle - heavy goods are pretty usable. Checkout genshock.
a steam turbine driven off the rad
Temp not great enough but, though potential with other fluids other than steam - its under investigation...
Stirling engine is it?
At that Thot, the efficiency would be sweet FA on stirling.
generator attached to an exhaust turbine.

Sort of under way, in a round about way - problem is slowing and cooling the exhaust increases losses in the engine, so you can really only scavenge off-throttle energy (which is small) and give it back on acceleration. But this is under investigation too. As is thermoelectric generation from exhaust and coolant.
