There is plenty of energy out there to capture, it's just a matter of whether or not it's cost effective to do so. For better or worse, economics drives the vast majority of these sorts of things.
Also, all of the lost kinetic energy that you mention is really small change in the grand scheme of things. Just think about using an exercise bike...if you crank up the resistance pretty high and pedal with all your might, you'll just barely be able to keep a moderately bright light-bulb lit while you work out.

Aha, my music buddy!
I see what you mean about the bike, etc. It's like the ball they invented that I mentioned, won't capture enough to make a difference - but when you think of how much in total there is to capture. Whoeee. I found some books about energy capture, I'm going to read a few and see if I can clear my head on this issue. I keep thinking of certain things, like all the semis running back and forth across the country - just that alone, how much would that generate?
The oil companies would probably start killing people off, but that's another thing entirely.
That extended video about the solar roads was interesting if a little to promoie.
Nature itself provides nearly unlimited energy. The sun is one example but geothermal is another yet closer to home. Just think of the amount of energy say in a volcano and if we could tap a smallish portion of that would likely be enough to give up on most fossil fuels. Yes volcano emissions are a pollutant. But it is polluting no matter what we do anyway. Geothermal springs are another source of energy. And if we started to drill deep enough toward the mantle, there is boatloads of energy there as well. If we survive long enough I am sure we will end up harnessing that energy.
Yeah that's a great example.
Hey auntblabby what is a skeleton watch? Do you just mean a watch with a skeleton on it?

basically a watch with a see-through cover so you can see the internal workings.

Oh cool. Hee hee, I really thought you had a skeleton on it. I was picturing the arms moving to tell time.
that would make a good watch also.

Lately, I've been a little obsessed with the idea of energy capture. I keep seeing the world as a huge mass of energy transference, except that we are not using the transference the way we should be. Instead of having our own energy stored and reused, we are doing stupid things like using fossil fuels.
I had the idea to implant energy capturing tools on sidewalks thinking it would get a lot of energy, but apparently I'm not the first to think of that and it is said it wouldn't be all that much of a helpful amount (I'm not sure I believe that, from just what goes on under my window alone).
Anyway, I saw somebody had invented a kids' ball that collected energy from being kicked, great idea but still not catching a ton of energy.
But would it be possible to invent an energy capture tool that we could carry with us and whenever we saw some form of massive energy source, just sort of clip it on and capture it? If you think about everything that is moving in the world, how are we letting all that go to waste - oh and don't get me started on the sun!

I suggest you study thermodynamics. In particular the second law of thermodynamics. While energy is indeed conserved when used to do work it is degraded through an increase in entropy. Look up entropy and enthalpy.
Used energy is never as good as fresh new energy even though it is conserved.
