Free energy

Free energy until the energy is used up.

What's the expiry date on magnets?

The amount of energy a magnet can release is equal to the amount it stores. In the video above no energy is being created whatsoever just passed from the magnet to the fan to the lightbulb, with some loss due to the nature of the machine itself.

I've seen a few of these designs, and while they are for sure neat, they are usually a 5-10$ magnet, 5-20$ fan, a few bucks of electronics, and a 50 cent lightbulb. Add it all up and you could get years worth of 75 watt electricity into the lightbulb from the power company.

A small bar magnet would run out rather quickly IMO, but im no magnet scientist. Really the best application for these is something like a survival lamp, but as they already have the shake-able ones that market may be gone.

I've never heard that a magnet has a fixed amount of stored energy, you can actually make those fans for free, what other electronics are you talking about, the price of the lightbulb is totally irrelevant unless you include the price for the Electric company to remove it from your colon.

The actual magnetism in a piece of iron or in a permanent magnet is actually caused essentially by electrons orbiting in one direction more than the other, and the electrons are going to keep on orbiting, as far as we know, for billions of years, as far as we know forever, unless something interrupts them. So the little atomic magnet is going to carry on forever. There’s no reason why the magnet shouldn’t carry on.

Well the magnets have an initial cost, they certainly aren't free from the local magnet tree. Neither is there a computer fan tree, superglue tree, electric wire tree, nor steel pieces tree. The lightbulb is irrelevant however. I'm simply pointing out this machine has input costs.

I'm not sure if a permanent magnet would have the same effect, that magnet in the video looks like a magnetized piece of metal which i've been told lose magnetism over time, thus the name permanent magnet. I think a permanent magnet would fail to power much and a magnetized magnet yields as much energy as was put into it, with no net gain. Friction both on the air and any turning shafts needs to be taken into account as well as the heat created by this friction, at the shaft.

My main point is that these machines are not free energy, but rather cheap energy with a low scale application. I don't think that a large scale operation would be practical, such as a power plant generator. But a small scale application such as an emergency flashlight or another item would be a good use. Want to power your house with this technology? that is likely to cost you a good deal unless you have access to free magnets which would be the most expensive part.

Here are some relevant threads to perpetual motion magnet machines:

Why would you think this is some idea to replace the Electric company, that's a pretty irrational baseless fear. Magnets don't grow on the magnets tree, but experiments like these are meant to increase your perception, not simply confirm your bias.

Did you actually read the links or are they simply copy pasta, I like the first one:

So a bunch of these kinds of videos exist showing how to make basic generators out of perpetual motion mechanics that are kept in perpetual motion with a little magnetic help. Now to quickly deter anyone who will argue that perpetual motion is impossible because of loss of energy and friction and air resistance, I say unto you that all those things are weak forces, easily beaten by a much stronger magnetic force, like one shown in the linked videos.

"Oh, but that video only shows a tiny device, a much larger generator could not possibly sustain perpetual motion even with magnets!" And to you I say WRONG.

Why are you linking info that shows the fallacy of your argument?

"replace the electric company"

"irrational baseless fear"

"increase your perception"

ok you seem to be well off the rails at this point.

I'm a mechanical draftsmen, i work in an engineering department at a company that makes machines for practical purposes, based on cost inputs. I'm simply looking at a machine and gauging its effectiveness in different applications.

The higher you amp up the scale of this and the longer that it runs the higher the heat from friction will raise at the shaft until the machine fails. That's simple me looking at the machine and saying "hey this wouldnt work for a 24-7 application to convert electricity" (i.e. an electric company's or individual's electric turbine generator). But would work for an item that needs to run for a short duration an infrequent amount of times, such as the emergency flashlight i eluded to.

People often look at a device like this and think "hmm they should make x, y, and z out of this" without taking scale into consideration much less the output of friction and practicality of construction. This wouldn't work on a large scale without massive magnetic input which would be expensive or some sort of cooling apparatus to offset the heat from friction which would also be expensive.



so because a single forum post on a single thread i linked discounts what you think im saying i'm wrong?

the force negation of friction can be beaten by a magnet, thats obvious, the machine moves. The heat from friction does not get negated by a magnet, the magnet creates it. Regardless this isn't a true perpetual motion device because it will break down, that is the crux of any perpetual motion device. The only true device would need to be free from friction held together by some other force, perhaps magnets.

Didn't you study statistical data for Law or something like that, now you're a mechanical draftsmen too, do you put unemployed gamer who shit posts on your resume too?

I have a bachelors degree in criminal justice and a minor in stats, specifically criminal justice stats. I was going to law school until last spring semester while also holding down my current dayjob as a mechanical draftsmen. I got this position because i needed money to put me through law school, started as an assembly position on the floor right out of my undergrad after a very short stint in insurance sales. A draftsmen upstairs was fired a bit later for looking at porn so i bought a textbook for Autocad 2013 learned the basics in a week and applied for the job. I convinced the engineering manager to give me a shot and 2 years later am still here. I was going to law school while working as a draftsmen but was approached by the CFO to start grooming for a project management position instead. So my choice was between paying 40-50k$ more to finish the last 1/2 - 2/3 of my law degree or having my 2 year degree in project management paid for me by the company, which is about 10-15k. So a 50-65k$ swing in my debt. Plus PMs here make between 80-100k so the tradeoff with a lawyer in my area was negligible. I will complete my PM schooling hopefully next year at semester break, but perhaps in the spring if i cant fit a class into my schedule.

Any other brain busters Card_Sultan?

you know the last few times you've played this Card (pun intended) i've challenged you to run down YOUR educational and employment history and you disappear every time. Will this be any different?
