I read 2. as about moving the storage unit itself. Charge the unit at on place then move the unit and generate power at another place.

I often find the following analogy useful to have in mind a-(b-c) = a+(-b+c) = a+(c-b) a/(b/c) = a*(/b*c) = a*(c/b) a*(/b*c) is not legal syntax in most languages, but why not?

In all seriousness, civilizations, dumb or not, are natural processes. There is very likely something we don't know about advanced civilizations.

I became suspicious when TFT was spelled out as Thin Film Translator and sure enough the whole piece turned out to be somewhat mumbo jumbo.

You do get a boost from the wave contracting and converging towards the opposite point from halfway around the earth. I think it is not at all obvious what the order of damping will be.

The /r^2 factor is due to the fact that the surface of a sphere grows proportional to r^2. That will hold for the wavefront half way around the earth, but from there it will be reverse. The energy will converge to full strength at the

It is enough to think about the part of the sound wave, a ring, that travels horizontally to see that it bends with the curvature of the earth. The front of the wave will at every point "shoot" some of the energy horizontally forw

Sound waves are points of high pressure and points of low pressure. At each point of high pressure the pressure tends to spread uniformly in all directions. Likewise at points of low pressure there is sucking from all directions. Opposite d

Sound waves can diffract around objects, which is why one can still hear someone calling even when hiding behind a tree. : http://en.m.wikipedia.org/wiki/Difraction

Your perfect "textbook" must be structure free in som sense. The classical textbook imposes a given structure which may or may not suite the teachers ideas of course form. The flexible learning resource is the problem to be solved

The "complex one" is better because it is correct. I don't know C#, but as I read your program, I'm pretty sure it's wrong. It seems like you just do a depth first traversal. That way you can't get breadth fir

I'm just trying to say that one should not neglect the importance of damping factors in dynamic systems. Our human environment is a complex dynamic system. No one can tell what would be the right amount of evolutionary progress without

Innovation is not stifled. Look around, we have plenty. But we can't have too much. Evolution should happen with reasonably stability. Evolution takes place on the border between order and chaos. Innovation is promoting force. We need
