    Portable Laser Projectors!?

    I have been on a eternal search for a portable/pico laser projector! It may seem like an odd thing to want, but from what I have been reading, laser projectors are more environmentally friendly, require less power, and never need to be focused. I could take it with me and start projecting...

    Is my Doctor a Quack?

    Stop Smoking the Laser Way

    Saw an item on the Fox News channel about a "cold laser" treatment that claims to help people stop smoking. Apparently it works similarly to acupuncture. Judging from the cost of these "treatments," I figure people stop smoking because they can't afford to buy smokes any more. Here's a link --...

    The Dry Ice Laser

    The whole thread on rectification of room temperature heat into electric power brought back memories of my days reading a newsgroup on free energy. Quite a few unsuccessful ideas popped up. But the one that caught my interest, the dry ice laser, almost looked like it would work. The laser...

    A quick laser question.

    Just say I had an 820nm 200mW laser. What colour would it be and would it do to my skin? And my eyes if I shined it there? Thanks muchly.

    Question on Laser Concepts

    Has anyone ever heard of anything called "laser concepts" or something similar? I heard a commercial advertising it, I think its a company's name, but I wasn't really paying attention. The only bits I heard were "lasers" and "acupuncture" and my woo detection meter spiked immediately. If...

    Laser treatments to stop smoking?

    I was listening to the radio the other day when I heard a commercial for a center that helps you stop smoking through the use of laser treatments. The commercial stated that a patient could return for unlimited laser treatments as long as they did not smoke. So I'm thinking, well, duh! "We'll...

    Laser anti-smoking therapy

    Anyone heard of this one before? I ran into someone today who claimed to have become a non-smoker thanks to a laser treatment. He said he went to a health centre where he lashed out £26 to have a laser stuck in his ear for 30 minutes, after which he stopped smoking. The way it was explained...

    Laser Tasers

    I had a thread about the threat of lethally modded tetanization beam weapons . Well, here's the org. that's working on the non-lethal ones. How long after they enter service do you wager the U.S. Military will have a company create a lethal version? Really quick I'd bet. Bullets can't top a...

    Color laser printers

    Does anyone have experience with either the Xerox Phaser 6250 or the Minolta Magicolor 3300? I'm in the market for a fast color laser printer and those two seem like good choices. I'd jump on the Xerox, except that there are some negative reviews at Amazon. ~~ Paul

    Laser / lightning risks

    There is currently much media talk about pilots being temporarily "blinded" by land based lasers. A technician was arrested and confessed to pointing a fibre optic testing green laser he bought on ebay for $100 at an aircraft. Green lasers certainly can affect night vision which peaks in the...

    Phosphorescence and lasers: why do laser reduce the effects of glow-in-the-dark stuf

    I recently "charged" some glow-in-the-dark material and then shined a laser pointer on one part of it. After only a few seconds, I removed the laser light and noticed that the targeted part glowed considerably less than the rest of the material. Why?
