The funny ufo...

[Angel of God]

I think everybody knows how it goes up...
Isn't it?...
The important is to know the same electromagnetic force of the electric engines...
Also it is used from some illusionist to goes up a lady who sleeps...on a bed


What do you think about ufo history?
Has it been science..?

 

[pgp_protector]

Actually most* illusionist don't use magenetic levitation

*Actually I don't know of any that do.

An ufo is an unidentified flying object, so in theory every object in the sky could be a UFO. However most of them have been identified.

Plus most people do not understand many aspects of aerospace engineering, just because you dont understand it doesnt mean it uses alien technology. Just look at the sacks a6 from ww2, if people had ever seen if flying they would have described it as a classic ufo, slow hovering look and a disk shape.

I don't believe in alien technology...
I was sure.
Without a propeller or exhausts.. it's surely an electromagnetic force that goes up!!!
Do exist other systems?..

I agree at 99%!
Note.
Scientifically it's wrong if scientists don't use this technology to land on the moon...
It seems to me it's the best way to land on the moon or mercury...

In order for a helicopter sized object to actually lift up using electromagnetism, it would have to use insane amounts of energy, it is simply not viable. Although good point, according to Flemings rules on magnetic fields given enough current theoretically it could be possible

Hi,
I think that calculation is this:
(F=)iLB=mg
i=mg/(LB) E=R * i^2 * Time
L can be a great value, calculate for L=1000 m. ...

Example:
m=400 kg, L=1000 m. , B=1 T.(good permanent magnet),Time=1000 sec.
i=4 A. E= R * 16 * 1000 J. = R * 16 Kj ...

Can it be right?..

I think that's all right!
It's sufficient an electrical wire with a tickness of 5 mm2...
It would be interesting to know its load resistance...

It seems electric current runs without
load resistance...
Infact there is not magnetic flux variation...

Are you wanting something with EHD like an ionocraft:

Tesla imagined such a device. To solve the energy problem, tesla foresaw charging the Kennelly-Heaviside layer from a multitude of bases stations (which is theoretically possible but there could be sever consequences in nature). Energy could then be drawn to to any point on the earth at any time, sort of like a reduced lightning bolt that could be aimed. This would provide vast amounts of energy to every corner of the earth.

Do you know its power/weight ratio?
Its motive force?

 

[mrpiddly]

possibly something like:

F=Id/k

F and I are obvious, K is ions coefficient through the fluid , and d is the gap of air between the layers of conducting material. For every watt, it should theoretically be able to lift about a gram, although this depends on several other factors such as the air gap and materials used.


To make a untethered craft capable of lifting any significant amount of weight would prove extremely difficult. Plus, when working with charges of that size, any person in the general area could suffer a fatal shock.


Maybe if you used a superconductor, which would still have to be cooled to 140k while in mid air, an ionocraft would prove useful for lifting larger loads but that could require some serious scientific and engineering effort.

It seems limited...
Its movement is created from collision between ions and neutral air.
Ions movement is important...
