New Battery Technology Powers For 12 Years
wellington map writes "University of Wisconsin-Madison scientists say they are developing a new lithium battery technology capable of making batteries smaller, last longer and, soon, accept a charge from outside the body without the need for surgery. These organosilicon batteries are projected to power tiny implantable devices for more than 12 years."
MADISON, Wis., Oct. 3 (UPI) -- University of Wisconsin-Madison scientists say they are developing super-charged tiny lithium batteries to help treat nervous system and other disorders.
Key word there, 'developing'. The article gives basically no information at all about how it works.
I remember a story about human-powered pacemakers and such though - did those pan out? Seems that those would be more useful than these low-current batteries.
Buying & changing batteries for people like me with a cochlear implant is a major pain - something like this would be fantastic.
What about preserving power in a capacitor and using a coil to recharge it from background radiation? By now people are constantly in a sort of electromagnetic field, so if you switch between two of them you should be able to generate a current, with a few proper diodes etc. you could charge a capacitor with that... given people that are still alive and enough mobile phone use, it would work?
You might just get into a fight with the people next to you, since you're in a way using their mobile phone battery to reload your pacemaker. On the other hand, calling in public and in hospitals would become accepted and even encouraged.
But when are they going to get me a laptop that can last 12 years bewteen charges!?
Instead of lithium organo-what ever why not use decay from an alpha source with a long (20+years) halflife? the alpha emmissions can be shielded by a modest tianium/glass shell
In the not too distant future, next Sunday A.D.
