Tiny Gold Nanomotors Spin 10 Times Faster Than A Race Car Engine

Nanomotors are an amazing feat of engineering: tiny gold rods less than a micrometer long, powered by ultrasonic waves to spin at crazy-fast speeds. How fast? Scientists just figured out a way to measure, and it’s astonishing: 150,000 RPM, 10 times faster than the fastest race car engine.
