It can assert that many students are able to construct a flying disc; it's enough to know and to be able to use the rule: F = i l X B. In fact making to pass the current electrical to a magnetic field it would develop a force; it is able to raise and to travel a flying disc. Easy!, practically the momentum of electrons is transferred to the small boat. Moreover the disc can remain firm in a point and can turn around to itself calmly remaining in the same place. It's enough therefore a little: a system for the generation of the current, etc...........[]


still before feeling in TV that the Russians had sighted a UFO I already "had constructed" it.  [xx(]

I have no idea what on earth you're going on about

Am I dead? Am I alive? I'm both!

It's a sure system (all alive) in order to go on.

You don't like my translator?
I have not found better.

What a cool site.  Had no idea it existed.  I can have fun with this one.  Thanks.

Most of my sub-contractors / installers are Mexican and some speak very little English. That website allows me to translate all of their labor and driving instructions into Spanish. I love it. It's very accurate and can be very fun.

What a great site Ians Daddy! Shame it doesn't have Indonesian - I'm going there in a few weeks and I'm madly trying to learn as much as I can.

I add:
i=10A
B=1T also permanent magnets
l=1000m
F=10000N
F is a force that succeeds to raise also 1000 Kg.

Good bye!

Thanks for clearing that up Zichichi, I'll sleep easy from now on.

I wish I could follow this formula better. It sounds fascinating.  I hope "Good bye!" doesn't mean forever!

A while back I bought a book for my son called "Build your own Laser, Phaser, Ion Ray Gun and other space age projects"  I'm dying to try out some of the projects.  It has all sorts of "levitation" devices and really powerful lasers.  There's even one that is supposed to be able to melt metals from several hundred meters.

It's another hobby that I don't have time for, but it sure sounds fun to do stuff like that.

OOOH! I want a laser! I'm going to get that book. That does sound fun.

[tweener]

It sounds fun, but the power supplies look like a real challenge.  And collimating the laser is quite intimidating.  Maybe someday...

I bet the publishers of that book have taken out some hefty insurance indemnity. There'll be people taking more than just their eyes out if they get their DIY lasers working !

I bet the average DIY laser would consume a very small amount of power, but the amount on power required to melt metals in a relitivly short period of time would be enormous. I seem to remember that the USAF proposed a series of Star Wars satelites that would have been able to incinerate a warhead. The problem was that the satelite would have to spend months recharging before it could supply enough power to do it again.

The key to melting metal with a laser is to collimate the beam to a very small area.  That way it doesn't have to consume huge amounts of power, it just puts all it's power in a small area.  It really isn't hard to build high power electronics, you just have to be careful.

The "Star Wars" lasers (and other stuff) were truly high power, because they were aimed at melting quite a lot of metal in a relatively short time from a great distance away.  The real problem was more in the tracking and aiming than in the power generation.  Fascinating stuff.

Truely.... I thought that the power consumption and regeneration was a problem. Do we have any idea how much power a photovoltaic pannel can generate? I found an interesting web-page <a href="http://www.ecoworld.org/Home/articles2.cfm?TID=248">here</a> that explains why we don't see a lot of PV power generation on the market today. I would think that any satelite at GeoSyc orbit would have full time light at a much higher density. Another thing to ponder of course, is the use of super conductors for the wiring in the areas not directly in the sunlight. Interesting.

I believe most of the big lasers in SDI were to be ground based.  The space based weapons were interceptor rockets.  PV energy would not be enough to run a laser that could damage a distant missile, and is hardly enough to run the comm gear and computers.  Nuclear energy is an option, but I don't know how seriously that was considered.  Mostly, the environmentalists won't allow it, but with classified military stuff, I guess they don't know about it.
