The Challenges of Tapping Blood Flow For Power 143
joshuarrrr writes "Researchers in Switzerland have tested small turbines designed to fit inside a human artery, like an implantable hydroelectric generator. The turbines can draw about a milliwatt of power, which would be enough to run a pacemaker. The problem is that the turbines tended to create turbulence, which can cause blood to coagulate into clots. Competing systems avoid the turbulence but have trouble generating enough power."
