Lets develop a car's engine. We can do it in 1 or 2 years, test it, do research on it, and use the data gained to develop the next generation of the motor. The cycle of creation and testing linked to time truly matters! People often forget that building and testing a fusion reactor takes 30-35 years, especially in the past. With such a slow cycle, expecting fast results wouldn't be logical. Fusion research has a very time-consuming development cycle. If you want to know about progress, find data on specific research advancements. For example, magnetic fields for fusion are 10,000 times more efficient than 20 years ago. There's been great progress, but there are still hurdles to overcome. Superficial judgments are easy, but they're simply misguided.

Envisioning a groundbreaking new use for something, is infinitely easier than the trial and error process of turning a theory into a useful tool. Not only that, but it's not just the linear problem solving of engineering the whole thing. You have to figure out every step in the theoretical process and then turn that into a machine that can do what you need it to do. It most likely takes more time to build fabrication technology up to par for the new tech than it does to actually engineer that new tech. and that was only generation one... See how it can take years to move forward? When you look at the situation, actual time spent on the new tech is limited by the speed at which fabrication can keep up. Imagine you run into such a novel problem, that is a known solution, but the fabrication technology doesn't exist... You stop doing everything on the new tech, and start over with the fabrication tech... It's not just a straight forward thing.

A little thing about graphene synthesis. There is a company out of San Diego called Grolltex which has made strides in synthesis and fabrication. Their CEO did his PhD thesis on the subject, too. The main bottleneck is not necessarily the synthesis of pristine graphene, but transferring and fabricating on different surfaces. That's what this company is trying to do. I know the sad joke about graphene being able to do anything except leave the lab, but the number of companies that are working on scaling, the number of companies working on graphene fabrication infrastructure, and also the very smart people in materials synthesis labs have put out lots of papers recently on the subject. There is one professor at Johns Hopkins who is working on graphene synthesis via CO2 splitting, which is exciting. If you're an aspiring materials scientist or chemist, this is a great field to be in right now.

Theranos and FTX failed because they wooed the public and venture capital, but they did not at all consult with accredited experts. The name of the game is Due Diligence.

"Electrons can only be in a few discrete layers, or shells, above the nucleus, which we can call bands" A band is not the same as a shell. A shell is what you get if you have more-or-less isolated atoms (or molecules), like in a gas or a liquid. A band is what you get in denser materials such as crystals, and it's a collective thing involving the entire structure of the material. A shell only allows one energy (e.g. the ground state of the hydrogen atom has an energy of -13.6 eV, take it or leave it), but a band allows a whole _range_ of energies, which secretly are like lots of little shells extremely close together, and shared across the entire material.

It's not that the theory making stopped, it's just that we only now have the fabrication technology to start working on where the theory has led us. Take an engineering course and chemistry for that matter...

​@@percywhitehead9228 Do a search for graphene chips and you'll find a dozen large channels covering this very breakthrough. I don't know how you missed it, especially, seeing as though, its sounds as if, you keep your ear to the ground on these topics!? Do you watch Sabine Hossenfelder ? She even covered it...

You didn't mention what the "height" of the ladder steps represents, which would make it hard to understand what the gap is supposed to refer to for anyone who doesn't already know that we're talking about energy levels.

Amazing video as always. Thanks alot.

Excellent presentation Sir.

We’ve been hearing about twice as fast processors and half the size 10 times better batteries every year for 20 years. It’s never happens either because it’s not possible or those up top who get rich don’t allow it.

Are you referring specifically to graphene? Because computers in general have gotten consistently two times faster or smaller every few years for the last 3 decades. Slowing down now, but only recently

Prototyping isn’t easy

I feel the need to point out that, faster clock speeds are not simply limited by the silicon. As clock speeds increase, you start to have a problem where the signals are bIeeding through as RF noise faster than they are traveling across the intended circuit. If the signal "jumps" the circuit gap, then you start to have all sorts of timing problems and the circuit would become increasingly noisy. So, a lot of the circuitry would have to be replaced by opto-electronics which would drive the prices sky-high!

The era of robot domination is getting closer every year

To everyone complaining in the comment section. All the “future” tech that disappeared or “isn’t being used yet” is being used they just aren’t consumer products. So many wild things have existed in history that weren’t consumer products.

They've been talking about this coming soon since 2011...that was almost 15 years ago. Where is it?

The problem you speak of at the end (current leakage) can be solved while scaling down the transistors. When researching problems with leakage at sub nano level it was actually discovered that taking advantage of quantum interference of electron by sending waves shifted by PI you can actually achive near-zero current leakage.

With such fine scale structures you can achieve great results but at this stage the manufacturing processes are not there yet, well not for any large scale production. Deposition and layering are often done with sputtering in semiconductor manufacturing and is improcice a lot of the time. These structures can be made by placing individual atoms at the moment but production at scale has proved difficult.

we have been hearing these things for over 10 years and we have not seen anything on the ground

It feels like another one of those wonderful discovery you never end up seeing on the market.

Great video, keep up the good work.

No it's not, your chip CYCLES 1000 times faster BUT your OS, UI, display, etc.... ARE NOT..... Simply put, you have 100cc engine and 1000cc engine, in theory the latter is 10 times more powerful, but IS IT FASTER? No, if 100cc is on a bike and 1000cc is on a car.

Interesting stuff, quite a break thru. Be interesting to see how long it takes to get in to consumer devices.

I have the Elecjet power bank and it’s such an incredible product! The crowdfunding experience was all but smooth, however the product itself truly feels next-level, so am happy that I backed it the end and got to try this new technology 😄

Sounds neat, but big skepticism until I see a commercial product.

My PhD studying electrical properties of graphene convinced me that it will never move beyond an academic curiosity. It’s totally impractical to work with even when you move beyond the exfoliated flake method.

Dunno why so many armchair scientists/engineers are hating. If you don’t have experience in the field, it’s not very straightforward to make a determination about how easy it is to process this material into useable, consistently-behaving, scaleable devices that do anything better than today’s technology. The number of papers making bold claims about the potential practical applications of the authors’ graphene research that only lead to an interesting study, far outweighs the number of papers that actually did deliver something beyond pure research. At the end of the day it’s just my opinion, but it is at least grounded in actual experience processing graphene into devices. So as cool as it would be for graphene to deliver on some of the things its been claimed to be able to do, I’ll believe it when I see it. It was discovered 20 years ago and we’re still waiting for it to impact society.

I'm an ingeneer specialized in powerelectronics. We are working since around 2019 with SiC Mosfets. here are some conclusions in comparison with standard IGBT Moduls (although I obviosly can only talk about powerelectronic side, not microelectronics) - If they die (explode) they do so pretty quite, that's nice. They also don't push the silicon everywhere. I tell you, cleaning a cabinet where a IGBT did explode is annoying... - They are faster. witch IGBTs our switchingfrequency was at (depending on the output current) 2...10 kHz, with SiC we are usually at 12...20 kHz with comparable current. That reduces the losses in the chokes significantly, and reduces the noice by far. Sadly it seems, that the chokes are now at their limit. even if the output current of the Semiconductors could be increased, there are no chokes to smoothe the current out. with 25 kHz most choke technologies are also already at the optimum with copper and iron losses. - They survive overvoltages longer/easier. - they get extreamly hot, therefore the chip is a lot closer to the baseplate (wich is attached to a heat sink. sadly this increases the parasitic capasity, and because of that also EMC noise against PE. It easily interferes with other devices. An EMC Filter is mostly required. - because of the higher switching frequency parasitic problems have gone up a notch as well. For example: we build a bidirectional, galvanically isolated DC//DC converter. In the lab it worked with 30 kHz, but when we build it in a cabinet, we had to reduce the switching frequency to 17 kHz, just because the cables were a few centimeters longer, and therefore the parasitic inductance inceased. The difference is, again, the lab compared to a real application. - they are, at least for now, still very expansive All in all, it is nice, yes, but it is not the all mighty solution. All the manufacturers have already quited down significantly about innovations.

Fyi, for those of you other there that like building your own pc, they make Graphene thermal pads that take the place of thermal paste for CPU's. Personally, I even take my GPU apart and put a pad on the GPU dye. I've used the same pad for years now, even reused a couple in multiple builds, still working great.

gaslight, gatekeep, graphene

Thanks for sharing it. ✌️

Power drain and heat generation of modern electronics is not due to wire resistance, it's due to gate switching speed getting maxed out. Transistors take a moment to change their resistance value from high to low and back, and during that transitional period they pass a lot of current at non-insignificant resistance through them, which generates heat and wastes power. Faster clock speed means there's less low-losses time between switching, and more high-losses active time. The only way you can help it is to develop a gate that flips faster and shuts harder, like GAAFET technology. Clock speeds are also severely limited by physical size of the chip - speed of light and all.

Computing really needs to take a chill pill!!!

This chip actually came from the future and found in 1984. It was smashed and no longer functioning. We were able to reverse engineer it.
