Ask HN: Why can't I use my body fat to power my devices?

2 点作者 mozak1111超过 3 年前
Hi - This sounds like sci-fi brain storming, but I am actually asking a serious question.<p>I often think that the key to weight-loss in 21st century could be some kind of way to convert energy stored in our body to electricity. Maybe you can plug in your laptop to your body, or have a chip inside your body to mine Bitcoin or whatever. After some research, I assume the generated energy would not be that much but the goal here is to find a way to burn [use&#x2F;waste] the extra energy so that you can lose weight.<p>Any input on this would be appreciated.

Put a generator on a stationary bike and plug your phone or a usb battery into it.<p>Besides, we all know the best use for human fat is soap.

1. Very, very small energy potential. 2. Infection concerns. 3. Much, much simpler ways to do it much more effectively. 4. That being said, implants are getting more and more common, it won&#x27;t be too long before finger pricks are replaced by injected sensors, as the latter is already a deployed technology, for instance. 5. It will happen on some level, but weight loss &#x2F; gain isn&#x27;t just energy in and out.

It takes 600 Kilo Calories to replace a pint of blood so maybe some sort of maggot box that You feed your blood to that can then have their heat converted to electricity through peltier plates?

You would need a glucose fuel cell.
