An unpowered invisibility cloak…

 

Watch this. There’s no electricity involved, and also no smart government operatives. The US and Canadian military couldn’t see much potential. The inventors tried to keep it secret and give the military a heads-up but they’re only getting replies now that it is on youtube. Another case of incompetence rising to the top in Western bureaucracy. If the West survives it will be despite our governments…

UK Express: Invisibility breakthrough: It’s cheap and it’s thin, and it would foil heat-seeking cameras as well.

Yaron Steinbuch, New York Post: ‘Invisibility cloak’ straight out of Harry Potter is now a thing

HyperStealth Biotechnology Corp. has announced four patent applications for “Quantum Stealth,” its own version of the fantasy cloak that could be used to make things appear to be invisible.

“It can hide a person, a vehicle, a ship, spacecraft and buildings,” the British Columbia-based company said in a statement. “There is no power source. It is paper-thin and inexpensive.” …

It works just by bending light. An optical illusion.

“It bends light like a glass of water does where a spoon or straw looks bent except I figured out how to do it without the water or volume (thickness) of material,” he told the news outlet. …

“The light comes from the sides and comes out the middle,” CTV’s science and technology specialist Dan Riskin said.

“You think, intuitively, that the light comes straight through the middle and comes and hits your eye, but the light that’s coming out the middle has bent there from around (the sides). It’s the bending of light that makes it look like it’s not there at all,” he added. …

There are many less obvious applications, Ciaran McGrath, UK Express

“Hiding shadows in the solar industry can potentially solve the problem of the newly MIT developed 3D Solar Towers from achieving their potential of 1 Terawatt solar power generation.”

“With the laser splitting, apart from the many military and commercial LIDAR type applications, I can foresee quantum computers utilising this as it solves two of their big requirements: millions of  and room temperature quantum computing.

“Currently quantum computers need to be industrial cooled and just a little, they need very cold temperatures to operate, whereas I demonstrate the splitting at room temperature.”

No actual clothes yet due to the distance required around an object.

        Bill in OZ, you really are in Oz !

        This so-called invention is a piece of junk.
        Unless you are a magician.

        With a carefully written promotion story.
        And YOU fell for it.

        It does not hide that well.
        It will surely be expensive.
        Tanks can be detected by heat.

        You said:
        “The gubermint ignored it” ?

        No, they did not ignore it — they rejected it/

        The claim that the inventors tried to keep it secret is total BS

        Inventors promote their inventions, they don’t try to keep them secret.

        Mr. Oz, I have a bridge in Brooklyn, you may be interested in buying.

        I’ll sell it you for half of what I paid.

        Always remember the classic definition of a gold mine,
        that could be updated for this worthless invention:
        A gold mine is a hole in the ground with a liar on top.

        Have a nice day !

          Looks like it’s a near/far focus thing done at the macro (maybe micro) level (modified Fresnel lensing?).
          Reflected light rays from distant objects are closer to being parallel to each other than reflected rays from close objects.

          Look at the man with the ‘cloaking’ shield in the video — when he’s close to the shield his outline is observable but very blurred with the background still clear. As he moves the shield away from his body the blurring intensifies but the background still does not blur. I suspect that there is an optimum distance from the ‘cloak’ for this to be truly effective.

      Just saw another U tube video from an honest scientist. He didn’t refer to this article.
      He had smallish pieces(3×5)of a similar semi-transparent camouflage film. Turns out it is a variation of a Fresnel lens made by fine grained Fresnel lens formed into one surface.
      With his small samples they had a field of view of about 45deg. Holding it in front of a couple of dowels he demonstrated that only horizontal lines could get through. A pair of gaudy, orange-handled pliers was completely obliterated into nothing.
      Turns out the same thing can be done by imprinting very small Freznel lens, which probably is the type used in the hype piece. With circular lenses anything seen through the lens is fuzzed into invisbility.

      Only camouflage problem I see is that with the computer power available now a program could be written to find what size and structure the lenses have and back calculate what was fuzzed out. The computers in many cameras and hi end phones do a similar thing. The light coming in flares over more than one pixel, but in a very predictable way. Process each color at a time and you can calculate how much light flared around the center pixel and add it back. Doing that for each color triples or quintuples the brightness and resolution.

    No electricity, I just found this information;

    O/T but at 11.17am with temperatures in Dodgy Danistan headed to 30 degrees, and winds howling a gale, power has been cut – either deliberately or due to idiotic Labor-caused fragility of supply – to thousands of houses, air conditioners, refrigerators, food-freezers, shops, supermarkets, factories, warehouses, traffic lights and train lines right across the State.

    Our $46,000.00 richer-per-annum Dodgy Dan is today blaming everyone else but himself and his Party of wallet-stuffing gullible dills for all the problems.

    Gee, wasn’t that a good Labor decision to criminally vandalise our State electricity grid and cut our power output with nothing other than Labor Lies and Greenie Fairydust to replace it….”

    So basically all you need to do is get your tank or fighter to operate within a large plastic box?

    (also there is no point in blocking a thermal signal if the blocking material itself has a thermal signature. You don’t have to look out for the thermal image of a tank anymore, you just have to look for a large rectangle that doesn’t match the background.)

    Yeah, pretty sure the US and Canadian military were right.

    (although, just for trivia, the desire for ‘visual stealth’ with aircraft dates back to when military aircraft were first invented and hasn’t really stopped. In WW1 the Germans experimented with using a transparent plastic instead of fabric on some of their early ‘R Class’ aircraft. It worked… unless it was bright and sunny, in which case it helped the sun reflect off the aircraft. The material also, iirc, didn’t handle moisture too well.

    (In WW2 the Allies (I want to say British, but going by memory and it may have been a joint project) experimented with placing lights all over long range ASW aircraft. The theory was a bright aircraft against a bright sky would offer no contrast and hence it would be easier to shadow enemy surface units or to sneak up on U-boats. The practice however was that it absolutely worked, however by that stage of the war every man and their seal had air search radar and it was considered being hard to visually spot was no longer worth the effort.)

      Compare and contrast with the pattern used by the Berlin garrison component of BAOR during the Cold War.

      At the time ‘normal’ British military vehicles were painted ‘normal’ camouflage based on the sound theory that they would be fighting in ‘normal’ areas. The Berlin garrison of course was expected to be fighting in Berlin, a rather urban environment and as a result had a pattern that was base dark grey with irregular white and dark brown squares over the top.

      Also, while we are on the topic of British armour, the Caunter Scheme. This dazzle style camouflage pattern was used by tanks in the Western Desert from 1940 to 1941. It is a hotly debated topic for tank fans and has been described as a carefully scientifically designed pattern, a compromise based on the fact the Western Desert Force had to source their paint from the RAF and everything in between.

    21 Nov: UK Times: Extinction Rebellion disowns co-founder Roger Hallam over Holocaust remark
    by Oliver Moody, Berlin
    One of the British eco-warriors who founded Extinction Rebellion has been disowned by his allies and rebuked by the German government after insisting that there was nothing “unique” about the Holocaust.

    Roger Hallam created a schism in the radical protest movement yesterday with an interview in which he described the Third Reich’s systematic murder of six million Jews as “just another f***ery in human history” and said that genocide was “almost a normal occurrence”.
    His remarks caused widespread offence in Germany, whose modern culture has been profoundly shaped by its efforts to atone for Nazi crimes.

    Mr Hallam, 53, a former organic farmer and sociologist, was one of the three Britons who set up Extinction Rebellion in London in October last year…

      mosomoso:

      Why hide the gas plant? Just route the electricity cable via some island (Timor? some spare island in Indonesia?) where they couldn’t care less about CO2 emissions. The gas plant could operate anytime they need the electricity and Australia’s Greens wouldn’t be able to see it, much as they celebrate getting to “50% renewables for 5 minutes” without asking what happens at other times?**

      ** Latest from Sub Australia the ‘big battery” is to be up-graded from (maybe 2 minutes supply to 3 minutes supply) with adoring commentary in the media about how Sub Australia is now got more reliable generation and a safer supply. That they are not getting any extra supply (indeed a slight reduction) doesn’t bother the media. Nor, since the battery will use low priced renewable electricity*** to charge and periods of low supply of renewable electricity**** to make money, will the public benefit.

      *** i.e. when the wind blows strongly and the wholesale price drops in order to dump it onto the grid and get the RET subsidy
      **** i.e. when the wind doesn’t blow very much and there is a shortage of generation (filled by the Big Battery at a profit). The effect is to reduce the amount (time) of low wholesale prices and increase the amount of high wholesale prices, thus raising the average RETAIL price.

          The current policy is that the older Torrens Island units will keep going until the end of March, to provide cover though the hot weather and peak demands.
          When they shut down SA will have slightly less reliable capacity.

        :) Thanks KK

        ….CO2 is the only molecule known to (climate) science that can absorb infrared and then direct it, like a laser, to earth instead of scattering IR in every direction like the other chemicals and elements……amazing how CO2 can absorb heat, and then direct it back to earth or hand ball photons of heat over to other CO2 molecules so they can stop the IR (infra red) from getting away into the upper atmosphere.

        Obviously the invention/cloak of invisibility takes advantage of this property of CO2 that seemingly knows which way is up and down, as though it can distinguish up and down by using gravity.

        For example, the sun emits infrared to earth and CO2 catches any infrared …. and then re-directs it to earth….CO2….. , even though there is very little in the atmosphere, is able to selectively re-direct infrared heat energy that is absorbed by it back to earth which creates the greenhouse effect….Hardened CO2 in the form of a kind of glass might have the properties of ……

          CO2 also has the property that the central carbon atom has two oxygen atoms linked to it.

          Unfortunately these oxygens find each other repulsive and are in a constant state of agitation trying to get away from each other.

          This makes it look like the CO2 molecule is constantly bending and reversing its appearance.

          Some scientists have commented that it’s like watching a politician over the course of a day, dodging, weaving and shape changing.

    21 Nov: SBS: Qantas executive says flight delays caused by climate change
    Stronger winds caused by climate change have led to increased flight delays and cancellations over the past three years, according to a Qantas executive.
    The company said above ­average wind strengths had contributed to a slump in on-time performance, most notably within the past four months at Sydney airport.

    “We have seen wind ­velocities 34 per cent higher than the average of the last 30 years, and it’s a prevailing westerly ­rather than the south-south-westerly we’ve seen in the past,” Qantas Domestic chief executive Andrew David told The Australian
    “That’s led to runway closures, meaning (aircraft) movements are slowed.”

    Mr David made the comments during the airline’s investor day on Tuesday, where he backed a recently announced Qantas commitment to work towards zero net carbon emissions by 2050 as part of a long-term ­environmental campaign…READ ON

    21 Nov: The Hill: Supreme Court weighs lawsuit pitting climate scientist against skeptics
    By John Kruzel
    The Supreme Court on Friday will consider whether to take up a prominent climatologist’s defamation suit against a venerated conservative magazine, in a case that pits climate scientists against the free speech rights of global warming skeptics.
    The dispute between scientist Michael Mann and the National Review has drawn attention from lawmakers, interest groups, academics and media, as the court weighs adding a potentially blockbuster First Amendment showdown to an already politically charged docket.

    Scientists hail Mann’s lawsuit as a necessary defense against efforts to erode public confidence in the scientific consensus that climate change is an urgent threat, while free speech advocates have rallied around the iconic conservative publication.

    The case has made for strange bedfellows, with the National Review receiving backing from the Center for Investigative Reporting, which has produced award-winning coverage of climate change; Senate Majority Leader Mitch McConnell (R-Ky.); The Washington Post; and the American Civil Liberties Union (ACLU).
    “The only way to protect free speech for our allies is to protect it for our adversaries,” Arthur Spitzer, ACLU D.C.’s legal director, told The Hill. “Today it’s unacceptable to deny climate change, but yesterday it was unacceptable to deny that homosexuality was sinful, and tomorrow it may be unacceptable to deny that robots are better parents than humans.”…

    The ACLU sounded a similar note.
    “Society can’t progress unless people are free to express and consider heretical ideas,” Spitzer said, “because there’s no way to predict which heretical ideas will be tomorrow’s truths.”…READ ALL

    20 Nov: E&E News: Emissions: Booming Southeast Asia’s dirty secret: Coal
    by Nathanial Gronewold
    SINGAPORE — Southeast Asia has one of the fastest-growing economies in the world, but intertwined with that rise is a rare distinction: a shift toward the use of more coal.
    The Association of Southeast Asian Nations is “the only region in the world where coal is expected to increase its share” of the energy mix, said Keisuke Sadamori, director of energy markets at the Paris-based International Energy Agency.
