The first Blood-Powered Heart Turbine is here
posted May 17 2011 19:56.07 by Giorgos Lazaridis

This tiny little gadget comes from Swiss scientists who designed a blood-powered turbine that can fit in arteries and power internal electronics, such as a pacemaker (for the present) or a mathematic brain co-processor (for the near future).

Pfenniger explains:
The heart produces around 1 or 1.5 watts of hydraulic power, and we want to take maybe one milliwatt. A pacemaker only needs around 10 microwatts

Each turbine can produce some 800 micro Watts of energy. Read the original article in this link.
