THE TRANSHUMANIST SCRAPBOOK: INVISIBILITY CLOAK ONE STEP FURTHER WITH ...
While we're on the subject of three-d printing and "teleportation"(see yesterday's blog), we might as well talk about another thing that it is enabling to take one step closer to reality: invisibility through meta-materials engineering. This one is near and dear to my heart, because way back in my very first book, The Giza Death Star, I speculated on the possibility that special kinds of crystals could be grown, perhaps through the use of nanotechnology, which would effectively trap light inside the crystal, through a special kind of negative refraction, imagining a whole series of "dark crystals" - dark rubies, dark garnets, dark sapphires, and so on - that were brighter on the inside than they were on the outside, so to speak. And in the Giza Death Star Destroyed, in spent some time with the Bablyonian Enuma Elish epic, and Marduk's "invisibility" cloak.
It should come as no surprise that materials engineers and technicians are now entertaining very similar ideas:
Harry Potter-style invisibility cloak is a step closer to reality: 3D printed device that bends light could make objects disappear
"These objects are put together in precise geometrical patterns to bend waves of energy in unnatural ways.
"In particular, they reveal a property called 'negative refraction', meaning they can bend a wave backwards.
"But metamaterials with this negative refraction have presented a vexing physics problem: They reduce the strength of the wave.
"'One of the biggest problems with metamaterials is that they produce energy loss,' Professor Xin said.
"'The waves decay as they pass through the artificial material. We have designed a metamaterial that retains negative refraction but does not diminish energy.'
"In fact, the synthetic material not only prevented energy loss - it caused energy gain, with the microwave intensifying in strength as it passed through the material.
"Professor Xin achieved this by embedding battery-powered tunnel diodes – which is a type of semiconductor device - and into the new material.
"'Many people did not think it was possible to achieve energy gain along with negative refraction,' Professor Xin said.
"He first showed it was possible, with one-dimensional metamaterials, in a paper published in Physical Review Letters in 2011.
"His new findings, reported in Nature Communications, have broader implications, because they involve 3D metamaterials."

This technology has been around for at least 5 years. I read this article when it came out in 2011, meaning by the time someone actually saw it, it had “been around”. If you get into high tech arms available to Joe Blow computer geek, I think you can buy all kinds of material that will either make you “invisible” to undetectable by the infra-red armed police looking to find you in your house…
Being able to appear or disappear at will or with a changed aspect is one of the siddhis or special powers attributed to the sages of the Indo-Tibetan traditions.
Thank you Dana – much appreciated.
Another rabbit hole to enter…
Can the good Doctor or someone familiar with the stories of people simply vanishing expand on this please?
Like most nowadays, I’m familiar with aeroplanes disappearing but not people. I’m interested in learning more about this.
The Break-Away arsenal is getting quite extensive. In my opinion, at some time they won’t have to be so stealthy. They’ll be quite in your face about it. It will be interesting to see what paths they choose to take.
How about the Romulean cloaking devices or the Philadelphia Experiment to hide vehicles of all types. As well a personal cloaking devices for spying and assassination, kidnapping uses. What humanity can fantasied they can at some time make real a lesion our official scientist have in the pass refuse to admit to.
Someone just bumped into an Aladdin’s Lamp of invisibility. With a few tweaks here & there; your only limits now, is your imagination.
An invisibility ray gun; set on kill, or just living as the invisible man looking for a cure. I can see this Invisible man talking to doctor invisible specialist, “was this through injection, pill, ray gun, or…?”
The Tablets if Destiny?
The Invisible aspect open one’s eyes to another Pandora’s Box.
Oh what a tangled web we invisibly weaved…
When first we practiced invisibility.
“Moderation” is getting to be the new “normal”.
Perhaps it was the word that rhymes with shill.
