Given the energy shortage the world is facing today, we are constantly trying to switch to non conventional sources of energy like from sun, wind, water, nuclear etc. But I think that adding this additional layer of transducers in between is not efficient. At least today, these transducers consume a comparable amount of energy to work than the energy they produce leading to low efficiency.
A more efficient way to get energy is from humans. Just imagine that your mobile phone is constantly getting charged as you hold it in your hands. We humans get our energy from food. So why not use the energy from within to power other devices. But how can we come up with a non-intrusive way to do this? For the uninitiated, non-intrusive means that we cannot insert wires or implant devices into human beings. A simple possibility that comes to my mind is to use the heat energy emitted from the body to charge devices. But the problem here is that these amounts are usually much smaller than what are required by the devices. Plus, we will still need some transducers in between. So this idea does not sound good technically.
Ultimately we do need transducers at some level and the proposed idea does not help. If it helped, we could just feed the sources from which we get our energy directly to these transducers. It is just the coolness of the idea of charging your mobile phone by holding it in your hands that initiated this thought process in my mind.
So, I do conclude that the above idea does not make much sense.
But still, if such a thing happens, there are serious social implications of this. Can you imagine a scenario where the poor become energy slaves for the rich? Some kind of employment will just be to sit in a place and pass on the energy to other things. This scenario will just be like Matrix movie with the only difference being that there it was the machines that made humans their slaves for energy. Some countries whose average obesity levels are quite high could come under a serious threat. Imagine India invading US to get more slaves who can eat much more and hence give more energy.
