Magnetics in Anti-Gravitational vehicles

[Particle]

Would it be possible to use a magnet to oppose gravitational forces to float a car or anything?
How safe would that be to walk under it?

Also how could orbital rotation play into it?

Also could something like this replace wasteful fuel such as used on the space shuttle? Using 'Local' energy more efficiantly could maximize usage.

1. If you want to use magnetism to make a car float, it needs be able to reach right to the core. I don't believe you can make a magnetized object adversely affect the gravity around it.

2. Dunno but maybe with such magtenism i can imagine all your bodies materials will go bjorked.

3. You'll need something that can handle a high rate of spinning in a very dense and compact manner, the only ones i know of are in big labs, i dont think its physically possible yet to fit something like that in a size of a car. And if we ever do, that will create its own gravity in a spherical shape and we will have a car that will not travel in a horizontal manner, but it'll be rolling and flipping around like a ball.
Im saying this because the most common object that spins and creates its on gravity is the cores inside planet, thats why our planets are around. I may have a genius(lol) idea though with something like, what if we had a flat iron disk and made it spin at ultra high rates, that might change the shape of the gravitaional field it creates and something like a slab of metal that reflects any G field going to the top, that makes a bowl shape anti-g field

4. Nothings impossible in the future, but i can imagine alot of technological breaktrhoughs needs to be discovered first. You'll need something that can manipulate the size, shape, and force of anti-gravity for this to be possible, same with the cars.

I thought about this also...

We could lace all the roads in the world with iron shavings and little bits of metals, and then create powerful electromagnets under the cars to harness the magnetic repulsion effect....kinda like those ships in The Matrix.

I don't know how that would work...there are alot of obstacles.

- Most cars nowadays are made of steel/iron, both of which are magnetic metals. Creating a powerful electromagnetic field under the car could cause it to collapse on itself instantaneously upon ignition.

- The kind of energy needed to create a 2-inch barrier from the ground surface for a 2-ton car is enormous. Short of nuclear reactors in the engine compartments, I don't think we have the kind of energy necessary. (Note - Back to the Future : plutonium rods)

Also:
"A magnetically levitated or "maglev" train set a world speed record in Japan yesterday, reaching 361mph during a manned test run. Maglev is part of a government project to develop faster, quieter trains. Japan's conventional bullet trains, introduced in the 1960s, are among the world's fastest."

you could line all the highways and roads with a thick metal strip about 3" in the concrete. A powerful magent could stradle this metal sheet. As with oribital compensation, the earth doesn't have an acceleration great enough to throw the car from the magnetic field holding it to the metal (not to be confused with earth's velocity, people). You'd need a powerful magnet of the same charge to produce the lifting force required, but somehow place attracting magnets on the sides to keep the car from repelling off the strip entirely. Walking under it safely? how safe do you feel walking under a junkyard electromagnet holding up a couple rusted cars? it's all about you're comfort level about magnets.

As for lifting a rocket into space, no, magnets would not be able to do that effectively. Not only would it require nearly the world's electricty for that moment in time to power electromagnets, but the accleration caused by the magnet tower would be so instantaneous that it would crush anything not internally reinforced (living or non). Railgun principle is the only way a projectile of that size could be lifted into space. But seeing as we don't have a tower 500miles high for the slow acceleration astronauts are used to, we'd need to provide enough anti-gravitational force to compensate earth's gravity in, oh, 500ft. squishy!

you all need to learn and read about NICOLA TESLA and the TESLA COIL, it can do what we need today and has been around for over 100 years , no flaming what you dont know go read if your into science you ll enjoy, and you ll be pissed at the end of what could have been...
Cars with a reciever arial for power, houses to, extreemely high current trains/ super fast......the list just doesnt end....
go read people....
And it FACTUAL SCIENCE, been done and proven.......in the u.s.........

 

[mdchesne]

receival arial? I wouldn't want enough power to power heavy duty electromagnets arcing to my car, let alone through the air. microwave transfere of every is one thing, but high voltage AC?

 

[AsianriceX]

There's a reason why arc lights failed and the incandescent light bulb succeeded.

Not only would I not want to hear random arcs of electricity being transmitted to my vehicle, but have you played C&C? Those tesla coils can wreak havoc on people

There is no doubt Tesla was a brilliant engineer. There is no doubt he would have advised you to take your own advice; "learn and read". Just for starters; a wire does not carry electrical energy, the wire determines the direction the energy takes. The energy is carried by the electro/magnetic field (EM wave) of countless electrons perturbed by the applied voltage. The drawback in Tesla's technique is the lack of directionality with most of the energy not reaching the "reciever arial". This lack of efficiency was known by Tesla and was something he was not able to overcome. We may yet use his concept to beam power to the earth via satellite microwave transmission. With microwaves, we can provide directionality to the beam and efficiently receive it.

You need to read more on the actual experiments, he has lit hundreds of lights at 30 or 50 miles distance no wire, are you telling me if the wireless power network system was developed back then it wouldnt be as good as the one we have now ?
Thats a joke it all came down to how much money they could make how fast, nothing to do with science and what system was better.
He has hundreds of patents , he invented radio control, he invented the first crude radio to work, a device that osilates and CREATED an artaficial earth quake ,destroying biuldings around his workshop ,stuff on turbines its increadable, but nothing tops his TESLA COIL system designed to run off ac power supply, ac he had running at a freq that doesnt kill the human body, what did the companies do to it ? Dropped it to a freq that kills.... 50htz...
The science/TESLA COIL if you look close is not unsound just undeveloped, a very sad thing for humans, and over time we will probably see them used in military equiptment, as the AC power system is now so massive worldwide, a set of Coils of the size and nature to power the globe would fry the present AC system, it needs shielding, its a massive task ,not likely to happen on earth now , but the moon if we put a base there, Mars, these are real possibilities, only if we develop it, and at the moment theres just to much competition...

I may have a genius(lol) idea though with something like, what if we had a flat iron disk and made it spin at ultra high rates, that might change the shape of the gravitaional field it creates and something like a slab of metal that reflects any G field going to the top, that makes a bowl shape anti-g field.

First, I am a computer scientist so I do not know allot about hard science but I am very inventive and learning. I will try not to be too divisive. (STUPID annoying).

So you're saying that you can create artificial gravity "Indirectly" meaning spin something one place and then create the gravity in another? Meaning the Iron disk? Wouldn't that be like how a motor works? Spin the motor magnets to create a magnet?

The kind of energy needed to create a 2-inch barrier from the ground surface for a 2-ton car is enormous. Short of nuclear reactors in the engine compartments, I don't think we have the kind of energy necessary. (Note - Back to the Future : plutonium rods)

What about commercial magnets picking up cars in Junkyards? Would it take that much energy to repel a car's amount of gravity?

As for lifting a rocket into space, no, magnets would not be able to do that effectively. Not only would it require nearly the world's electricty for that moment in time to power electromagnets, but the accleration caused by the magnet tower would be so instantaneous that it would crush anything not internally reinforced (living or non). Railgun principle is the only way a projectile of that size could be lifted into space. But seeing as we don't have a tower 500miles high for the slow acceleration astronauts are used to, we'd need to provide enough anti-gravitational force to compensate earth's gravity in, oh, 500ft. squishy!

How would the planet scenario compare to a small piece of steel in a magnetic field or even a log under the ocean and how it floats to the top? So you're saying it would take allot of power to float it to the top and even then the small object would get crushed? This is different then an object in orbit around the planet where the object is being attracted by gravity but 'missing' the earth so it continues to rotate wound the planet.

Also, with the MagLev that is more like a lubricant. So you are directly repelling off of the magnetized steel there. How would you repel something off of the size of a planet's gravitational force per/object energy amount not the entire planet? Would you be able to create a powerful magnet under the car that would repel planet gravity; not the car itself but a separate magnet under the car? Also I don't know much about how gravity works and am still learning. Why does a planet's gravity work with anything equally while other types of magnets seem to only work with 'conductive' material or material with magnetic properties? Also I know there is static electricity that works with cloth but the cloth can't conduct electricity i think although you can create energy by rubbing two sticks together.

Also what about anti-matter?

 

[mdchesne]

piddlefoot, ac frequency does not kill people. it's the amperage. I think it's like .8 amps is lethal (correct me if i'm wrong, i want to know ) radio control is a totally different concept than wireless power, so don't even start putting him up on a pedistal for all his patents if none of them have any application with this thread. We also know you can power a 20watt lightbulb with just static electricity in the air. I don't know what wattage bulbs were back then, but that's not a direct power feed via wireless technology... he just supercharged the air with static. I bet if there were flourecents back then, there would be a lightshow for 100s of miles. What we are trying to determine is if there is a DIRECT route of power via a wireless terminal and receiver. I think microwaves would be the best use today, but the dishes are huge and wouldn't fit on cars. You need a form of radiation, not raw power. Radiation can be transfered in a laser-like beam to the individual car, then a device onboard could convert the radiation to usable energy. Like solar rays on sunlight. but because we need such emense power for our vehicle, we need radiation that will hold that much usuable energy and a way to beam it to the vehicle without radiation poisoning to the driver or people on the street

Another crazy question:

Could a laser shield work off of the atmosphere to surround the object and then move it? I am taking some of this from the movie:
http://www.imdb.com/title/tt0089114/
but I thought of the idea way before this movie so no I'm not living off of Holleywood.

 

[mdchesne]

not quite sure what you mean by laser shield. I don't see how light could move something besides the slight push the absorbtion process yeilds. If you're talking about something light the superhero Green Lantern and his ring of light (or w/e, fanboys know what it is), no. thats a comic
