Tractor Beams Are Now Real!

Posted September 09, 2010 8:40 AM

From Neatorama:

Okay, that may be overstating it just a bit. But Australian scientists claim to have moved small particles five feet using only light: The device works by shining a hollow laser beam around tiny glass particles. The air surrounding the particle heats up, while the dark center of the beam stays cool. When the particle starts to drift out of the middle and into the bright laser beam, the force of heated air molecules bouncing around and hitting the particle's surface is enough to nudge it back to the center.

"Okay, that may be overstating it just a bit."

AKA wild extrapolation, completely ass about on the principals, or in fact the stated direction of the effect.

What ever happened to science reporting on the science - as opposed to the glory of the reporter?

Peanuts like you set back energy reformation a decade by twisting 2 research programs into "Clean Coal". It's quite possible that bit of self gratification is solely responsible for climate passing the tipping point.

However; I like the idea that your probably young and will get to fully experience it.

Have a nice day

Look at the name of the web site! Probably oriented toward 3rd graders?

" However; I like the idea that..."

A) your young

B) your are young

c) you're young

If you answered "A", you are probably an engineer.

If you answered "B", you accidentally received an engineering degree from a school that shouldn't ought to be accredited!

If you answered "C", you wasted a bunch of (studying) time, "nose-to-the-grindstone", believing that the english language would NEVER suffer the sort of 'bastardization' that it now suffers day-in and day-out, anywhere and everywhere (including news anchors on tv!).

Hmmmm...my response here is about identical to: (see #12 at) THIS post.

Balloonists have long moved masses Far FAR greater using much simpler technology...!

Now, I would be TRULY impressed if they were spending the same money to develop an array of the ultra-tiniest "narrower-than-simply-invisible" nano-beam 'lasers' to assist with the detection (or "validation", "verification", or whatever term is appropriate) of the existence of other dimensions that physicists tell us MUST exist.

Guess they need to make $$ first, developing THIS (so-called) technology, for some kind of GAME , no doubt...!
