A real Cloak of Invisibility.

"Titled 'Demonstration of an ultralow profile cloak for scattering suppression of a finite-length rod in free space,' their research, published in the New Journal of Physics, describes a cloak consisting of 66 µm-thick copper tape and 100 µm-thick flexible polycarbonate film which scatters and cancels out incoming waves."
“In principle this technique may be extended to visible frequencies; in fact metasurfaces are easier to realize than metamaterials in optics. However, the object size that can be efficiently cloaked with this method scales with the wavelength, so when applied to optical frequencies we may be able to efficiently stop the scattering of only micrometer-sized objects,” the research paper claims.

It will never replace x-ray glasses.

I already have one. It comes with the Vodka and Candy Cigarettes.

I guess The Washington Post is going after the right-side-of-history demographic.

Yes, but do they have a Cone of Silence?

The best Cloak of Invisibility for visible light won't work if your foe has infrared glasses.

And since the article is about cloaking microwaves, well it's use for tricking the human eye is pretty limited.

I believe they have tested this compound in laundry detergent, and it makes one sock of a pair invisible forever.

Man, if it can hide responsibility and blame, politicians will pay billions to fund it.

Brilliant! No need for surreptitious activities. Theft, lying, bills passed and all kinds of mischief perpetrated in the open and in front of our lying eyes but without the knowledge of We The People.

Question: How do the congresscritters discern their own lying-partisans from the other lying, lying-partisans?

This has been around for about ten years. I met one of the guys who developed them. He signed a contract to be professor at our university, just before he got famous--so naturally he backed out and went somewhere more prestigous.

The range of wavelengths it makes you invisible to is very narrow, so even a visible light version would only make you invisible to one color at a time.

You can't fix that by stacking different ones, either--your red cloaking device is visible in blue light.

Yes, but its use for cloaking against radar is pretty interesting.
Think about it. you don't have to build a stealth anything. Just cloak it in this stuff.

Hey, did you hear the latest news about NBC executives inventing a real-life cloaking device? Have you heard that? Yeah. They decided to call it "ratings."

I've got one of those cloaks. It really works. Look I'll show you. I'm going to cloak the rest of this comment, and your won't see a thi

Be paid weekly and earn like a boss! I just bought a great Mazda MX-5 from having earned $7126 this past 4 weeks and $10k past month. Without any doubt this is the easiest and most comfortable job I’ve ever had. I began this 6 months ago and right away was bringing in more than $83 per/h. Here’s what I’ve been doing Rich45.com

If it only cloaks small things politicians will have to wait a few more years before the technology can hide lies as big as the ones they tell. Anyway, low information voters and compliant media seems to be working well for now.
