Science Nerds Assemble

You should look at the videos "energy from the vacuum" 13 part series.

Basically using different techniques they show you can get more energy out of circuit than you put in. He says it gets the energy from the ether. Using tesla technique of using pulses to create spikes and using electro magnets and the pulses you can create over unity or negative resistance.

Over unity is when you get more energy from a circuit than you are putting in.

Absolutely impossible. The zero point energy that popular science has seemed to clung on to as a source of perpetual energy is completely inaccessible. Yes, quantum field theory calculations shows it certainly exists, the energy in the vacuum is not zero. However, to extract such energy would require taking the vacuum to an energy state below the vacuum level. Such a state does not exist.

I watched the trailer, and it is absolute rubbish.

It wouldn't be perpetual motion in that case. Anyway the low efficiency and impracticality of such a device would mean it would never be built, solar panels are far better.

Groen, seriously, find something less wasteful to do with your time. Perpetual motion is just a way to exploit gullible people. All these supposed perpetual motion machines will have some source of maintaining power, even if it isn't obvious. For instance Cox's timepiece:

No I appreciate it wouldn't but in a sense because of the nature of the sun, and the frictionlessness of space, I thought it would basically run forever, which I stupidly assumed would make it very efficient. :(
Could even just leave it in orbit generating electricity into capacitors, then use laser to transfer to earth. Silly i know. :D
 
it is experimental science, we would not have electricity if tesla did not break through conventional thought barriers. I am sure there was a load of hardcore scientists back then who said exactly what you just said.

Tesla was just a gullible fool until he invented ac eh ?

ok what about this video, you think the guy is a fake? he is actually lying?

I don't believe he's lying, I think he's wrong.

"Adding comments has been disabled for this video." because they don't want people with actual scientific knowledge explaining what's wrong with the concept.
 
No I am fully willing to accept the possibility that the guy is mistaken and does not know what he is talking about etc. He may even be talking **** to sell free energy books. I still find the topic interesting though and look for videos of this nature.

Do you think it seems possible that using the repulsion of magnets that you could create a device that after a spin by a human that it could carry on spinning and generate electricity? the concept seems basic and plausible to me, what about you?

I still wonder what happened to these guys: http://www.youtube.com/watch?v=g59cGTswGCI

the australians that claimed to have invented the same sort of device as the bedini i believe.

All is see that guy doing with the batteries on his motor is slowly draining them?
"You can run a pump off it or even a car" ??? As soon as you connect it to a load it'll slow the motor right down and you won't produce anything to charge your second battery?

And his $1.50 Bridge rectifiers, thats not a 100% efficient energy transfer, so he'll be losing energy there all the time, and it won't "run forever" as the bearings will fail?

Anyway, obviously gash not worth thinking about!

It seems as plausible as standing still letting a large pendulum fall from your face, and it coming back to hit you in the face rather than falling short.
 
For instance if the bowling ball at 55s in this video smacked the woman in the face then yes it would be plausible.


Also if every bouncy ball acted like flubber or if a whole host of other things about the physical world were different it would be plausible. Infact if perpetual motion machines were possible life probably wouldn't exist.

Tesla invented stuff that actually worked, was reproducible, and didn't fly in the face of the most well established and successful principles of physics.

These 1000's of people playing with magnets and 'working on' over unity devices are not doing experimental science - they are jumping into the air and flapping their arms in different ways thinking that one day they just might actually fly. Sadly, gullible, uneducated youtube viewers can't tell the difference.

Actually, of those 1000's, I'd wager only a fraction are genuinely delusionally flogging that dead horse - most are more likely just trying to pull a more convincing hoax than the next guy for some youtube attention :).
 
If we have two types of electricity currently AC and DC, is there space for someone to invent a new type? Wouldn't necessarily have to be 'better' but is it possible?
 
Variable DC, square tooth AC or any shape of signal you can think of. Not really fundamentally different to AC or DC and no advantage.
 
This has probably already been answered, but there is such a thing as magnetic drag. Or more accurately, ripple torque. In a motor/generator you have various poles around the outside of a spinning magnet, you spin the magnet by applying an AC current or generate an AC current by spinning the magnet. But since you have (and have to have) more than one pole the magnet will still be attracted to the pole behind it, even as it is moving past. That's how it looses energy.

It will also be periodically attracted to the oncoming poles, so that mechanism isn't necessarily a big killer of efficiency per se. It does mean that output torque is not continuous though.

i heard the earth might be slowing down, and possibly might spin the other way one day

is has been said that the polarity of the earth will and has changed before. it might happen soon or a million years.

me and a mate invented a perpetual motion machine ages ago. in theory it works . we just dont know how much energy it would produce. it used magnets and the fact you can calibrate a compass to spin depending where you are.

he is a science nerd and im just a stoner though.

There is already perpetual motion machines I have seen them with my own eyes.

check out the over unity videos on youtube, many machines exists that run on magnets and charge a battery up while using it and the machine can run a light bulb etc for ever. Well as long as the battery and the mechanics of the device hold up.

There are tons of examples.

Sorry but that's BS. They might remain in motion for a very, very long time, but NOT perpetually.

For example, the ball is rolling on a track. This creates friction which heats the track slightly, and slows down the ball. The track then radiates this heat out into the air and it dissipates into the atmosphere.

With regards to the OP: yeah something in a perfect vacuum would keep spinning indefinitely. However there is no such thing as a perfect vacuum, not in space, and not in a lab either. Furthermore, any energy you remove from the spinning object (by ANY means) will be subtracted from the objects kinetic energy - ie it will slow down. All the spinning object is doing is storing energy by its motion, not creating it.

The only way to create a perpetual motion machine is to create a system in motion that somehow recaptures 100% of the energy it loses due to frictional forces (including magnetic friction). As far as current scientific understanding goes, this is physically impossible and anyone that tells you otherwise is either stupid or a liar.

Not really. DC is current flowing one way, and AC is current alternating direction at some frequency. There isn't any other way which isn't just a subset of one of these.

On the topic of energy..
Leccie prices are much cheaper at night, so why aren't more people buying batteries and charging them up overnight?
Click to expand...

Electricity is cheaper at night because demand is lower. If you moved all the demand to night then the prices would increase dramatically. Not to mention that you're just adding another source of inefficiency and removing some of the main advantages of having a national grid by using batteries (at least, i assume that's what you were suggesting).
