Dark matter optical coating for CDs
So specifically with regards to that and other examples:
1) What "completely false pretences" do you think they have commited, in their words?
2) What claims have they made, in their words, that in your view it cannot achieve?
The best way of being a charlatan is to invent a problem that doesn't exist, so you can say that you technically didn't lie, upon scrutiny. They're talking an awful lot about how to solve the problem, but the whole the description of the actual problem fits within a single sentence:
Dark Matter absorbs background scattered infrared light that could otherwise make its way into the photodetector as noise.
We are to take it on their word that scattered light will penetrate the aluminium foil, scatter, once again penetrate the aluminium foil and then that whatever is left of the light "could' be picked up as noise. We are expected to believe that the manufacturer of the CD player didn't cover the inside of the player housing with a material that absorbs all relevant wavelengths to prevent them from scattering inside the player.
So again, since they're failing to demonstrate that this is actually a problem, they're not technically lying when they're claiming to solve the problem. But, this bit stood out to me as well:
Coloring CDs improves the sound because colors, especially green and blue-green (red's complement) affect the visible red color portion of the scattered laser light - the laser is not, strictly speaking, monochromatic so there is some visible red in the background scattered light. However, the infrared scattered light - because it's invisible - cannot be influenced by color, i.e., there is no complementary color for infrared light. So other means must be employed to absorb it before it can reach the photodetector
This makes very little sense. They're framing the light spectrum in terms of visible and are talking about complementary colors, which doesn't make sense in the context. What does talking about complementary colors matter for light that will never reach the eye? "However, the infrared scattered light - because it's invisible - cannot be influenced by color ... So other means must be employed to absorb it" This describes IR light as something very mysterious, that only this magical product can block.
Outright lies? Not sure. Filled with weasel words for luring people who are illiterate about these things? Certainly.
Edit: Haha. Just looked at the rest of the site. It seems like the "Dark Matter" coating was literally the sanest product they're selling. Scattered infrared light? Infrared light exists, so maybe it does something. Who knows right? Now take a look at the "Blue Meanies", a sticker you can put on a wall to tune a room.
http://www.machinadynamica.com/machina47.htmThe Blue Meanie is neither a damper nor a resonator so it's location on the wall, unlike dampers and resonators, is not critical whatsoever. A Blue Meanie can be placed anywhere on the wall; it can even be hidden behind a picture or bookcase. Four white 3/4" removeable paper stickers are provided to cover the blue dots if desired, making them less conspicuous. Codename Blue Meanies operates via mind matter-interaction. The subconscious mind interacts with room boundaries, i.e., closed-in spaces, producing a claustrophobic reaction that interferes with and degrades the listener's sensory perception. It's like putting in a better set of interconnects. Price $99 for set of 4 Blue Meanies.
Mind matter-interaction. The subconscious mind interacts with room boundaries. Yes, totally not snake oil. Note how they're careful to point out that these stickers actually have no physical tangible effect, again useful if someone would have the propensity to claim that they're lying.
And of course, they have a pebble product.
