I’m disappointed that I never got my jetpack, promised to denizens of the future in the animated sitcom The Jetson’s from 1962.
But as a small consolation, I’ll take one of these:
MIT scientists have developed a way to spot rotten produce: A cheap electronic sensor built out of carbon nanotubes that can detect the ripeness of fruits and vegetables by measuring the amount of ethylene gas in the fruit.
The sheets of carbon atoms rolled into cylinders, with added copper atoms, will cost about .25 cents and when combined with a radio frequency identification chip will run about $1.00.
Next up are monitors that detect mold and bacteria growth.
These appear to be safer than jetpacks.
