I have a need for a magnetic insulator for an invention of mine. If you know of one, please advise.

Is it the advice of a physicist you seek - or an engineering solution?

[Physicist]

I have a need for a magnetic insulator for an invention of mine.

Since there is no such thing as a magnetic current, I don't understand what you could mean by a "magnetic insulator".

[Physicist]

That is circular logic, and doesn't really explain anything much to me. Gravity is a force, space/time are measures of variations.

I'm not sure what your problem is, here. Is it that you don't understand how spacetime can have a curvature, or that you don't believe that if you start with flat spacetime and induce a curvature, it will quantitatively and qualitatively exhibit every feature of a gravitational field, down to its last measurable detail?

[_Jim]

Perhaps he means (or needs) magnetic shielding instead ... "mu metal" anyone?

[Physicist]

Harvard scientists say they've stopped light: Speed of light is zero

Scientists at Scotch, Memorex, BASF and TDK say they've stopped sound: Speed of sound is zero.

121 - "Is it the advice of a physicist you seek - or an engineering solution? "

Well, as it is a practical and potentially real invention, a real, rather than theoretical solution would be preferred.

I do know that the NACA (now the NASA) flew a B-36 bomber (the HUGH bomber with 6 pusher props and 4 jets in two wing-mounted pods near the wing tips) with a full-size nuclear reactor on board in some kind of secret research in the 1950s. I read it was some kind of nuclear propulsion experiment. Never have read anything more.

... then you need to seek out an engineer rather than a physicist (no offense to physicists or "Physicist") ...

124 - "Perhaps he means (or needs) magnetic shielding instead ... "mu metal" anyone?"

WOW - _Jim, you may have just made up for all the hastles you have given me over the past few years. Thanks a bunch.

Now, if I can just find a 'gravity insulator', it would be perfect.

As I said, physics is not my area of expertice, but I do find it fascinating.

I remember what you are talking about. There were also some preliminary designs for super jumbo transports (600 ft wing spans) and bombers, which could fly on nuclear power plants for months.

However, it may have been after 3-mile Island, I don't remember exactly when, perhaps in the 50's or 60's, but someone finally figured out that the planes might 'crash'. So the whole idea was dropped.

[XBob]

127 It seems to me that they did get the powerplant to fit the aircraft, but they never flew with it on board and activated, and definitely never flew with it as a power unit. Long time memories, from when I was a kid.

[Physicist]

I thought a physicist would know the difference between an insulator and a barrier.

Explain to me what you think an insulator does.

[Physicist]

I need this for my commute.

And this is what I need for my commute. OK, I was just looking for a cheap excuse to link this somewhere. It's a really cool mpeg of a jet fighter breaking the sound barrier, up close.

According to this the nuclear powered version was never built or converted, only the testbed to study the effects of the reactor on the instruments and pilots.

There is some speculation that the B-2 has a small nuclear reactor onboard, that suposedly powers an electrogravity system that reduces the mass of the plane and payload by 89%. See here

It's not every day that you see people speculating to two significant digits.

[XBob]

a barrier blocks physical passage of something, eg, an aluminum wall is a barrier, but it is not an insulator, which blocks conduction of something less physical - eg heat, electricity etc. For example, the first electron to come out of the wall aluminum wall is not the first electron to go in, it is the last electron in the string of electrons which is bumped, and the first to go out.

interesting links - 134 - pretty much as I said - i remembered pretty good after all these years - "A total of 47 flights were made up to March of 1957. The NB-36H was decommissioned at Fort Worth in late 1957. It was scrapped several months later, with the radioactive parts being buried"

As far as the b-2 - being electrogravinometric, I seriously doubt that. it is 1970's-early 80's technology. And as far as airmen being electrocuted, that may be. All aircraft build up charges of static electricity and the first thing a ground crew does after landing and chocking the wheels is to ground the plane. As the b-2 has some special coatings, it may be quite possible that it becomes a giant super capacitor.

[Physicist]

In an electrical insulator, the electrons are not free to move throughout the material. If "electrons" are physical but "electricity" is not, then instead of thinking of a brick wall stopping "cars", think of a brick wall stopping "traffic".

As for thermal insulators and conductors, they are totally different things from electrical insulators and conductors. They work according to different physical principles. A diamond is a lousy electrical conductor, but there is no better thermal conductor.

Maybe if the theory of quantum gravity is proven, there will exist, as in all particles, a gravity particle and anti gravity particle which can be combined to zero gravity. Just wait about a century

[Physicist]

Under any formulation of quantum gravity, the graviton, like the photon, will be self-conjugate, that is, it will be its own antiparticle.
