The Neverending Powersource

Energy has to come from somewhere. A motor, when turned, creates electricity from the terminals. When electricity is applied to the terminals, the motor shaft moves. Backwards compatibility, anyone? The sun constantly gives off energy. The suns energy is used to grow food. Continuing on with the theory. So, in this example, energy came come from the sun, which goes into plants. Now, we can make the plants into ethanol, however, the amount of energy burned from ethanol is almost equal to that producing it. BUT, if we do not use the plants to make ethanol, humans can eat it. That, in turn, lets us function and work. Now, do you know what the near neverending powersource is? Do you? Animals. Humans in particular. So, to create electricity, we need some form of generator that creates electricity when work is applied to the generator. Hmm... I know! A bike generator! A human pedaling a bike generator that is connected to a motor creates electricity. Basically, we are more efficiently harnessing the suns rays. Yes, I have accounted for the amount of energy it took to produce the bike, motor, and other unneccessary accessories humans MUST have on that bike. But eventually, We may overcome the amount it was needed to produce those things. So, I will soon be creating an instructable on a bike generator, created from your previous/preexisting bike, that will be very simplistic to create and easy enough a 12 year old could do it. Remember, humans can harness the suns power even more effectively than other sources of green power. (I know this will cause a disruption in the comments, but so far, Nuclear is the cleanest, however the waste is not very good...)

Im glad this struck some comments. Most, if not all were informational and brought me into the "Laws Of Therodynamics and Superconductors!" Thanks All! -RoAr
[ missed this comment when you first posted it... ] You're welcome! You can tell that there's a small group of us who really enjoy these sorts of discussions. And for the educators (me, Kiteman, maybe others) there's the satisfaction of seeing someone else make new connections in their knowledge.

If you're talking about harnessing human activities to generate power, that is already being worked on.

Some club dance-floors use the pounding of dancing feet to generate electricity. Fabrics have been designed to turn bodily motion into tiny currents that could trickle-charge a phone, I posted a topic some time ago about a generator that attaches to the human leg, harnessing the flexing of the knee to generate electricity.

There is even a watch that runs on electricity generated by exploiting the difference in temperature between your skin and the air around you.

But... an efficient way at harnessing the Sun's energy? Hardly! Since both plants and humans run at a smidge over 30% efficiency, we'll be generous say that the devices do as well - that's 30% of 30% of 30% = not a lot.
Granted most perpetual watches seem to work really well with a simple generator from motion, I say perpetual because that's the general name, I'm not losing my mind.
I'm not saying it doesn't work, I'm saying it's not an efficient way of harnessing solar power.
I know, even the best of PV cells aren't particularly effective...

Let me rephrase that: --Another-- way to use the energy, instead of wasting it on just say, running, as in exercise. This is a way to actually make energy with the energy used for running, in this example. It's another way, thus increasing efficiency of overall use of the sun. Does that make it slightly clearer? That's pretty cool about the dance floors and fabric. -RoAr
Oh, we still talking about the same thing, as some gyms have started using their equipment to generate electricity.
No. Please see the forum topic on why thermodynamics is correct. You can't win, you can't break even, and you can't stop playing the game.
you can break even, kinda superconductors, if it's cold enough
