Human body could power smartphones, pacemakers and other devices

Does "other devices" include armies of malicious robots/AIs?

This isn't requiring us to eat more, it's just using the excess energy that's wasted.

I should think the sheer amount of energy wasted everywhere else in life, from my heatbox of a computer to my shitty car to my poorly insulated house, far surpasses the meager extra calories I could offer.

You're right about that, and plenty of companies are looking into it, but since your house and your car aren't regularly with you it's pointless, eh? Can't power a pacemaker with your house.

It's weird that you guys are pushing back with "there are better ways" or "this isn't green." This is looking at a problem: there are many devices on you regularly, some of which are very difficult to get to (e.g., attached to your damn heart) which need energy. At the same time, your body produces a lot of excess energy that goes nowhere. It seems like an easy solution. Even if we're not producing enough energy to permanently power a Pacemaker we can probably extend the lifespan of the battery considerably. And having something in your shoes, or wherever, that takes some of the energy of you walking to power a device in your pocket longer is a no-lose situation.

Yes, there are other forms of lost energy that are of a much high magnitude, but they aren't permanently with you. And yes, the human body isn't particularly efficient, but this isn't using the body to create more energy, it's using energy the body is already creating but not using.
