Default Laser-Powered Nanotech Gold light windmills

IR laser-powered gold nanotech light "windmills" invented ("light mills" - like regular windmills, but powered by light instead of wind).

Uses the interaction of light waves and nanoscale structures to create rotation - in either direction, depending on color of laser light.

Only 200nm in diameter, capable of doing things like unwinding a strand of DNA!

Also VERY high-powered - has enough torque to rotate an object 4,000 times its own size underwater! So also potentially useful as a propeller / propulsion for a nanoscale machine (aka nanites).

Can "replicators" be far behind?

Enjoy - while you still can!

Nano machines are just incredible! (and scary in a way)

Thanks for the story seoguy

This is why I am going into nanotechnology engineering, it's so awesome.

What precisely is "nanotechnology engineering", if I might ask? I mean, I know what the words mean, but what exactly are you going to be studying?

About nanotech engineering, its a very new interdisciplinary science, at this moment its a just a bunch of biology, materials, quantum physics, and manufacturing branchs. nanorobots like a regular robot can be designed to do almost everything. One of the drawbacks is powering this little machines (you can't use a 18650 heheh). IMHO powering them with light is a very promising way, cause you can drop some hundreds of them, with a laser select exactly where you want the action to take place, and after that simply wash them off.
