Glucose fuel cell

RatSomeone forwarded me this news story: Power from Glucose. The article is about how some scientists have created a device that can turn glucose into energy (while in the body of a rat).

I was curious what would happen in a diabetic… Would the excess blood sugar mean more energy, or would it gunk everything up? Could it be used to easily tell someone’s blood sugar level? If higher glucose level means more energy, that should be easy to display, don’t you think? (My husband was joking about little lights on my arm that we could glance at. If the light goes out, eat more.  If the other light turns on, add more insulin.)

Scientists were trying to come up with something that could fuel medical devices, but perhaps it can be used for glucose levels too.
