I understand a future tank would beat a future mecha, but the mere definition of a tank ensures limits as to what it can do, and I again point to some of the things a mech could potentially do as opposed to a tank.
The only viable mech barring some miracle tech breakthrough are powered armour suits

Not sure if anyone has seen this yet, but:
Quantum Stealth; The Invisible Military Becomes A Reality

CNN Interview here.

Apparently it's a camo that utilizes bending of light to render the person "invisible". Not sure how much of it is true, but they claim it works. It's also one of the camos adopted in Black Ops 2.

I remember there was a material that could bend light around an object, but it was a stationary kind of thing. They were talking about using it near industrial districts so the urbanites would see the hills beyond without seeing the factories at all.

eh....

"it works, for realz, we're not gonna tell you how, not even a hint, just trust us! those are totally not photoshops because we said so!"

yea... I'm skeptical, at best.

Active Stealth, like in Full Metal Panic would be a game changer for a lot of things. But can it prevent the detection of heat?

Imagine a new model Stealth fighter with both active and passive stealth. Not only might it not show up on radar at all, but you wouldn't see it either. But the effect of it being there will still be noticable I think. Noise, heat, contrails if they aren't careful. But you have to be looking for those things, before it puts a missile in your communications bunker.


Somehow I can already imagine the Israelis with something like that. The only way to prove it was them would be from the remains of the ordinance used.

Well, theoretically, it MIGHT be possible to create a material such that it refracts light all the way around the material and through the other side, like water running over a rock. And if it's possible with the visible spectrum, it should also be possible with radio/IR waves as well I guess. But this seems like quite a big jump, so I still have my doubts about this..

according to the site, it blocks IR as well, though tbh the way they're putting it, you'd think it can block a supernova explosion too.

The more I read it, the more it looks like hot air to me.

Scenario 4: One of the most vulnerable times for a submarine is when it comes to periscope depth to look around to verify the enemy, ships or aircraft are not loitering in the area, before the submarine surfaces or fires on the enemy. The periscope can only be hidden with painted camouflage to a certain degree. With Quantum Stealth; the entire submarine can stay hidden near the surface as well as the periscope above the surface which also cannot be seen.
I'm not even gonna go into the apparently magical cloth that also works underwater and is durable enough be used on the outer hulls of a sub, but I'd love to see how that could in any way shape or form eliminate periscope wake.

Oh I know, magic.

Scenario 6: A group of Canadian Battle Tanks in Quantum Stealth engage an enemy group of tanks, the only indication to the enemy of the Canadian Tanks location is the direction of the noise of the tanks engines and the sound of their guns firing. As the enemy looks through their targeting scopes to fire back, there is no indication on any sensor to where the Canadian tanks are located, nor can the enemy see the other Canadian tanks which are moving to flank them from the side and behind.
Even if their material can mask against direct IR detection, how are they going to "contain" the heat? even with exhaust cooling etc., eventually the heat would have to go "somewhere", unless of course, magic.

also, I'd love to see how that material is supposed to hide the tracks

Do I care that people remain skeptical? Nope, the people that need to know that it works have seen it and verified it and their opinions are the only ones that matter.
Then why did you make an amateur website talking about how great it is while stressing how the "US Military" is super interested in your work but you can't really talk about it. Actual secret projects are, you know, secret.

I feel that it needs to be said that this technology has been making the news for over a year now. For a relatable source, Cracked.com is one such place it's appeared. It's been on a few news outlets for science as well, I recall.

The most likely use of this technology will be infantry warfare. Ground vehicles, ships, and planes are all vulnerable to a myriad of different weapons but also have the capabilities to defend themselves, hence why we still use all of that stuff. Infantry is vulnerable to basically everything, and we humans simply aren't built to withstand the weapons we've produced for the specific purpose of killing humans and things we've built to kill humans. Even a mostly invisible soldier is a huge leap in saving lives from any threat that requires a direct line of sight such as armor, other infantry, and all sorts of other threats.

While a lot of you are spot on about issues related to large-scale objects and their ability to diffuse high quantities of heat effectively, those issues could technically be mitigated with some sort of cooling system prior to exhaust. Even if the exhaust was vented at a higher-than-average temperature to be visibly seen it would still be rather difficult to find in many environments.

As far as submarines go... Submarines are already capable of becoming basically invisible to all means in a specifically located layer of water below the surface. Sure, this technology could, in theory, protect them from being discovered at the surface. The issue is that this isn't WWII, and if a submarine doesn't want to be found it wont be.

If I've said anything incorrect, please be sure to let me know.

The problem with bending light around an object is basic -- you can't see shit if you're inside - just a spherical mirror if you bring your own light.

Not quite I think. With the development of nano-sized cameras and possibly VR-HUD, those things could act like giant presidential cars and still function - albeit the images and sounds are streamed and not real time.

P.S I know you and your colleagues already had a breakthrough in that area long time ago. Share please for the sake of science.

The only major invisibility breakthrough I've heard of was years ago when they managed to bend light around an apple from one angle. Which is to say completely useless considering the same effect could be achieved by using a camouflage blanket according to your situation. :P

TBH, it would've been more convincing if the guy had just said "we can't show it what it looks like in action because it works too well!".

or "you see your facebook profile photo? I was actually right behind you!"

I find it shocking that despite all of my interest in things like this, I never really considered this.

The nice thing about humans is that if we were to completely cover them in this invisible material and leave only small holes for their eyes, you would still have a 99+% invisible person. Spotting and engaging a tiny little disc of white and brown/blue/green from a distance would basically make you superhuman.

Also, there's this: http://en.wikipedia.org/wiki/Oculus_Rift

Break through against Leukemia.

This method is still in its experimental stage, but the impact it can potentially have in the future at fighting disease is exponential. I was all excited reading through the article.

Just one step bigger from the vaccine, no?

But actually, this is kind of genetic modification-lite, at least in effect; not quite modifying the genes themselves, but the body and its immune system and more importantly how they work. Very, very promising.

The question is will it be available to all? Cause a lot of these people are poor.

This can cure everybody but not everyone could have it. That's a painful fact.
