we know everything about you..

The beam would have to be reflected to a detector no, and even then i don't see what information the beam could carry back.

The only thing i could see is that if the beam could be broken due to not being able to pass through certain molecules and hence a broken circuit. Maybe different molecules have different frequencies that the beam can/can't pass through?

Yeah, determining molecules by that is called spectroscopic analysis, I learned it in A-Level Physics :)

If true, although i don't see how it would be accurate at that distance, then all one needs is to lather one's self with so much chemicals that it scrambles the sensors.


Pointless, completely, entirely...pointless.

Once again only really harms stupid criminals and the rest of the population, smart criminals are usually in league with the very people who say they "defend" us, so its laughable.

The point is you can't really scramble it, I'm guessing it works on specific frequencies as above, meaning if you set your scanner to "cocaine" the ONLY thing it will detect, EVER, is cocaine. The beam would just pass straight through your layer of chemicals. Then while they're arresting you for possessing coke, they'll be laughing at you too for rolling in shampoo, baby powder and splenda.

If everything I just read is true and none of those claims are exaggerated (highly unlikely), then this will be a fantastic, yet scary technology. If done right, it could be an end to a hell of a lot of crime, cut down massively on the time it takes to get through things such as airport security, create cheap, quick and perfect medical scans, and numerous other helpful applications. If done wrong, we could end up just not leaving the house for fear of unknowingly breaking the law and getting carted off. I feel like the true application would be closer to the latter.

science really doesn't work like that.

A cliche response to a cliche statement, for the only reason is that he has a point and you have nothing better to say.
But yeah, if real it's scanning for dubious materials, that's it, unless it's harmful.

Topic is also stupid, as well as some people's understanding of what it apparently does, not in this thread specifically.
Sometimes I'm bemused by what people complain about in the effort of safety.

i just cant be arsed with the 'ive got nothing to hide, so erode our freedoms at will' stupidity to be honest.

the war on terror has already been lost when we lose our freedoms.

1984 wasnt a training manual

I remember watching this anime thing as a kid where to combat this mind-reading enemy, this guy stuck his face in some boobs and ran at her all horny so she could only see boobs when she read his mind. That's what I'll do when that day comes.

Huh, sounds interesting, name of the movie? :D

I had to check that wasn't published on April 1st.

While I imagine the underlying principles are sound I don't believe for one second a laser fired from 50 metres away is going to penetrate my pocket and wallet bounce off some cocaine on a bank note then make it's way 50 metres back to a detector through said wallet and trousers and set of an alarm in picoseconds. For a start it would take light 166834 picoseconds to travel 100 metres.

This is PR junk to get funding and most probably sell another generation of inefective scanners to airports.

This.

Such a molecular 'scanner' doesn't exist in a form that would make it feasibly useful.

Never said it did, I was being hypothetical. In reality, I highly doubt this will come to fruition in anything more effective than what we already have, but they'll tout it as next generation scanning to rake in a load of profit from governments. That's all it really is. Exciting concepts, not so great application.
