back to article US boffins tune into carbon nanotube radio

A team of scientists from the University of Illinois and Northrop Grumman Corp Electronics Systems has succeeded in creating a microscopic functioning radio constructed from carbon nanotubes, Reuters reports. The nanoradio consists of two radio frequency amplifiers, a radio frequency mixer and an audio amplifier, crafted from …

    Whats the point without bluetooth?

    Low tech the hard way

    When I was a kid, back in the 50s, I did the same thing with technology which was then at least thirty years old -- a bit of lead ore called "galena" and a fine wire. A tuning coil and capacitor were helpful, but not absolutely necessary.

    I'll be impressed when they turn out nanotube tubes (valves, auf Britisch) complete with filament, cathode, control grid, and anode. Screen grid and suppressor grid optional.

    creating a microscopic functioning radio constructed from carbon nanotubes,

    Which is powered by three car batteries.

    Not electronics at all

    I think you'll find that the "nanotube output transistor" is still waiting to be invented.

    That black stuff would also be cool because...

    we could finally do the black paint job described of the ship stolen at the Restaurant at the End of the Universe.

    Fantastic. Now ants can enjoy DAB radio

    While the rest of us can get our orders from the Alien Greys without anyone else overhearing. Nice to think the Alien Greys could respect our privacy when the government doesn't.

    Wasn't this reported somewhat earlier?

    Re: Low tech the hard way

    I think you missed the point that it's demonstration- they themselves said this application wasn't interesting. Obviously they still have a way to go, but demonstrating these properties are an important first step.

    @oxo- It's not meant for radios or audio application. Think faster and smaller microprocessors that hopefully use less power and breathe more life into Moore's Law.

    A microscopic radio?

    we just made the worlds smallest radio! but we had to attach this keychain to it so you don't lose it..

    Presumably the only tunes it'll pick up are...

    "Diamonds are Forever", Shirley Bassey

    "Diamond Dogs", David Bowie

    "Coal Miners Daughter", Loretta Lynn

    anything by Neil Diamond, "Carbon 9" or "Carbon Leaf"

    I think you will find that Arthur C Clarke got there first with the Black Monolith ;-)

    Yeah, but...

    Can it pick up DAB? Sorry, wrong debate. I'm going.

    The Navy Black(tm) leather one please...

    What happens when you combine stem cells and nano tubes?

    Since stem cells seem to be able to do anything these days and carbon nanotubes seem to be able to do anything these days I can't wait until someone releases a drink made of stem cells and carbon nanotubes; it should give me super powers. I just wonder how it will taste? Probably like Red Bull.

    Blacker'n'Black evil super stealth aircraft chugging over friendly home base, flies through cloud of partial nanoradios suspended in atmosphere through "natural" forces. Nanoradio + Nanoblackpaint + atmospheric static electricity becomes highly visible complete nano radio transmitter. Bad black bogey brung low by blighty's bitsy boom box bits..

    Yes? Maybe? No? Oh, I see....

    OK, I think will stay anonymous on this one...

    make it wind mill powered

    such low consumption just normal air con moving air about would power it

    we used to call these …

    a fucking crystal set.

    Playing catch-up

    I love these "to challenge silicon" stories.

    We have been making integrated circuits on silicon chips since the early '70s and technological development had been driven rapidly by massive commercial investment. Those nanotubes are going to have to be very very good indeed to catch up as silicon has a three decade head start.
