How much energy could a device extract from blood sugar?
3 comments

"One single implanted GBFC device of 0.24 mL volume (2.4 mL for the whole implant) produced the power required to operate, using a specially designed electronic circuit to charge a capacitor, two types of electronic devices: a LED and a digital thermometer."

I'm waiting for someone to invent the implantable chip that converts blood sugar into heat/light purely with the intention of wasting that energy.

Grab enough power to monitor blood sugar, to make sure you aren't putting someone into a coma, but otherwise just try to burn an extra few hundred calories a day.

Why waste this energy? Couldn’t they devise a way to mine bitcoin with it? :)
Oh god, just what the world's food distribution problems need.
Good idea, but I’m guessing you’d have fever as a side effect ;)

Then you need to radiate heat somewhere. If you heat up the blood the body will spend less energy keeping warm leading to no benefit.

If you generate a lot of heat... it goes really bad.

Easy, simply install a venting port in the patient.
The first patient should be a congressman then, because they already have a hole they blow hot air out of.
It would be an enormously complex device, most of the sugar we consume gets converted into fat as we quickly cap out our "energy blocks".
Alternatively (and arguably much less complex and much cheaper): 1) eat less, 2) exercise
You're thinking too fancy - with our technology today, we could install a bypass valve at the pyloric sphincter that just dumps chyme into a stoma appliance/bag.
That's interesting. Seems like a low tech solution would be to give blood every day. I wonder if somebody has already invented the blood donation diet.
Problem with that is that we don't replenish it fast enough for that to work. Maybe with plasma donations but I'm not sure there either.
The real question is can that conversion be done in an efficient enough way with materials that are safe to put inside someone and in a small enough package.
