  The Top New Videos list is always full of interesting, current videos. It is always recommended that you have a look through the Top New Videos, but also have a look at these:
  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?
  Post and share it here - VideoSift is the best video aggregator on the Web, where we share, discuss, promote, and interact with the best videos out there on the web. Post it here, and share it with the large community of video-interested users. And - you are guaranteed to find more very good videos here already!
  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

The smallest radio that will ever be built

submitted by Almanildo

1 decade 5 years 4 weeks ago

This is incredible. A single nanotube performs all four of the core functions of a radio: That of the antenna, the tuner, the amplifier and the demodulator. Plug in a battery and a speaker and you have music!

See Scientific American for details.

that's pretty cool, they actually use they physical length of tube to vibrate at one frequency (the carrier) which then provides the demod because only the envelope generates current.
