Self-winding Pacemaker   (+5)  [vote for, against]
Magnet resonantly suspended in chamber to produce power

We are starting with a nice rhythmic heartbeat, why not harness that to power the pacemaker? The power cell is a spherical chamber with a magnet suspended in the center. The suspension is resonant with the standard heart beat, so the device could either be directly or acoustically coupled to the heart. The resonant design will allow even small vibrations to magnify till the power can be bled off by inductors arranged around the chamber to produce power.

Another percussion beat for the heart song under the stethoscope.

Aaah, no self-winding Peacemaker? Most of them are full of hot air.

//Another percussion beat for the heart song under the stethoscope// No, the central magnet should never hit the wall as energy put in would be bled out as electricity, so the magnet should just "swing" silently inside the sphere.

Ah, but think of the old school stem winder applications for this.

"Are you feeling okay?"

"Oh, I just forgot to wind my..."

"Quick - put him into the recovery position and make sure he's pointing due North!"

Good idea. Let the heart power itself. Certainly better than gluing solar cells to your hat.
