Uric acid is a strong electron doner. Some kind of oxidation cell could use it to produce electricity to power ones bionic implants. Don't really know about oxidative source...haemoglobin? Kinetic batteries could potentially generate alot more but with old folks sitting all the time this might be good
as a back up

So, um, you pee on it to make it go? |
|
| |
It goes inside you right after the kidneys..prob needs to have blood going thru it or some kind of refillable oxidative agent |

The natural source of uric acid in humans is the oxidation of xanthine by xanthine oxidase. The oxygen atom added to the substrate comes from water. Do you suggest water should be used as an electron acceptor for the cognate redox reaction? |
|
| |
I can't see any physiological way to recover the xanthine so that the supposed battery re-charges.
Obviously, the enzyme catalyzes both the direct and the reverse reactions, but unless some syndrome or oxidative stress is suffered, the 'forward' reaction outperforms the 'backwards' one. |
|
| |
If you put excess water into the system, you've got both an active person and a water-closet crowding because of regular kidney function. |
|
| |
Furthermore, the electron acceptor should be specific to those bionic implants, so, again, either my imagination is too short or the proposal is definitely halfbaked. |
|
| |
Mmmmh, in vivo chances are few.
In vitro, I really don't know. I bet you could pee into some 'battery liquid container', then tell the biotech guys to feed that into any electronic device. |

Your kidneys produce their own kebabs?
Wow.
sp. "a lot" |
