The meter is not a vector quantity. And....?

Sod off

I just gave a longer explanation and easier equation to understand. Not everyone knows vector algebra you know.

Oh, and photons (the constituants of these radio waves of which you speak) are the exchange particle of the electromagnetic force. Fortunate that they're there otherwise, otherwise there wouldn't be a force acting on the turbine to stop it.

Try reading the Elegant Universe by Brian Greene. It may not have the plot that Asimov's books do, but at least it hasn't fallen into the 'Dirty Old Man' phase that most sci fi authors do.

W says he doesn't have a subconscious. I say what the hell are you talking about you pretensious tosser.

Oh, and the force produced will always oppose the motion (Lenz's Law) Generation of electricity is done by a process described in Faraday's first and second laws. In my universe, Faraday was a famous Victorian scientist, which would mean that the physics is pretty damn old compared with the rest of what we currently accept to be true. When was Faraday alive in your universe, tony?

Lets start at the beginning. Under our current understanding, there are 4 fundamental forces. The strong nuclear force The weak nuclear force The electromagnetic force Gravity As per their names, the strong and weak forces only apply within the atom, leaving us with EM and gravity. Gravity only takes place between objects of mass, and is pretty simple to understand; F = GMm/r^2, where G is the gravimetric constant (a constant of proportionality), M and m are the masses of the objects and r is the distance between their Centres of Mass squared. There are however two basic equations that apply to the EM force, where we're concerned. One is of the form of the one above, with the masses replaced by charges and G being, of course, a different constant. The other equation is the one that we are interested in with reference to this phenomenon. It states that in a magnetic field, moving charged particles will experience a force perpendicular to their direction of motion. The equation for this kind of thing is F=Bqv. (F is force, B is the strength of the magnetic field in Teslas, q is the charge and v is the velocity) Let us look at the specific case of a wire. N = nAl is an equation we shall have to involve, as is I = nAve (N is the total number of free electrons, I is the current. e is the charge on an electron. What the rest of the symbols mean doesn't matter) Assume we're dealing with electrons (we are). Also let f be the force on an individual electron, and F be the force on all of them, and therefore the wire. f = Bev (just replacing q, the charge, with the charge of an electron, e) Mutliply both sides by nA nAf = BnAve but nAve = I so BI = nAf BIl = nAfl But nAl = N so BIl = fN The force on each electron multiplied by the number of electrons is the overall force, F so F = B I l Where B is the strength of the magnetic field in Teslas, I is the current and l is the length of the wire. As I have only assumed that there are free electrons (N), and this is true of EVERY METAL BY DEFINITION, it is clear that there will be a force there, 'even for copper'. Happy now? (idiot)

Nuclear power would do it, with ethanol or hydrogen for cars.

Not in the slightest.

If I wanted to travel to the future, I could do it by using Special Relativity.

We don't need fossil fuels for electricty or motion. Science could solve all of these problems, if it wasn't for damn things like the Anti GM brigade

Try to learn things that are more useful?

Oi, stop giving things I said in the 2nd post in the thread as new information

They're a bit tachy. HOHO.

As I said, thermal expansion of water

The crime fighting duo?

Water's odd stuff, and it's quite likely that this property is the only reason life exists.

It's true. There would be a slight rise in sea levels, from the melting of antarctica (it's on land), however most of the change would be from the thermal expansion of water. And we don't know about the rest of it.

Ali G's a college man.

Isn't that what my post says?

That depends how probable it is, and how alike the 'spawning' conditions were.

Strange, but very good, excepting The Business and Dead Air.

Well, for a start IQ doesn't actually measure intelligence. Secondly, online tests are usually not exactly accurate (for a start, it's in their best interests to give a higher value; you need a disinterested source). Thirdly, it depends how you define genius.
