New inventions

This article describes a couple of cool inventions. One is a transmitter that allows an individual to hear sound, while the person next to her hears nothing:

"It works by sending a focused beam of sound above the range of human hearing. When it lands on you, it seems like sound is coming from inside your head."

How convenient would that be when you want to listen to music loudly in the office-- even the best headphones seem to "leak" enough that your officemate is bothered.

The other invention, though, is even better:

"One of his most recent patents is for the AirScooter, a personal flying machine designed for commuting. It reaches speeds up to 55 mph and is light enough — under 300 pounds — to not require a license to fly."

Right out of the Jetsons, man. I want one!! But something tells me that machine would be regulated even more harshly than the Segway, if it ever becomes popular. Ah well, I suppose I'll just stick with my Prius...
