World's Tiniest Radiometer To Power Medical Scanner 37
BuzzSkyline writes "University of Texas physicists have built the world's smallest radiometer. The minuscule radiometer is only 2 millimeters across and operates on the same principles as the common light-driven toy, which consists of spinning black and white vanes in a partially evacuated bulb. The researchers attached a mirror to their tiny radiometer and used it to rapidly scan a laser beam. Their hope is that they will be able to incorporate the radiometer into catheters to drive scanners that produce medical images of the interiors of blood vessels and organs. The devices would replace micromotors in conventional catheter-based scanners, eliminating the need to run potentially risky electrical currents into the body."

You had me at "catheter" and "electrical current".

Look, I know it doesn't literally spin.
But the analogy needs to be rethought. Because, the Crooke's thing, a laser, and my urethra don't sound compatible.
sigh. some intelligent people should really be reclassified as savants.

This points out a need to revise the expression "where the sun doesn't shine."

If that's what you're in to. They had me at "replace".
