Could this be scaled up and used for weight loss?
By what mechanism? Capturing and stripping the glucose before it's digested naturally? Seems a bit roundabout since the weight we want to lose (primarily fat) is really just an energy store in the body in the first place.
Forget a brain implant. Can a device that lives on glucose help me lose weight?

An artificial means of controlling blood sugar would alleviate the insulin cycle and prevent the body from storing blood sugar as fat.
There is no actual need for dietary carbohydrates.

Quite well understood actually. http://en.wikipedia.org/wiki/Cellular_respiration http://en.wikipedia.org/wiki/Electron_transport_chain One of the fundamental biochemical pathways and required reading for entry level life-sciences degree programs.
What is the actual chemical reaction going on here?
I think the glucose present in the cerebrospinal fluid is there for a reason. Probably not to power implants. PS: I'm not a doctor.
Actually, I'm not sure it is. Not for an energy related reason anyway. I'd wager the main reason the the glucose is present is due to osmolarity when the CSF is being created from the blood. Also realize that the CSF has a high turnover rate, something like 3-4 times per day, so that glucose is being replenished readily. I doubt this chip uses much glucose in comparison (plus, they've probably thought of this).
My first thought was "Does this mean if I want a BCI, I'll have to start eating sugar again?"
