New Uranium Compound Could Lead to Atomic Hard Drives

image

In the future, hard drive capacity could be seriously expanded through the use of uranium.

Steve Liddle of the University of Nottingham has developed a single-molecule uranium compound that could someday lead to super-high capacity hard drives. The basic premise of the compound's potential is the smaller the magnet, the bigger the hard drive.

Hard drives currently use magnetism to do their magic. Liddle's compound is made of two uranium atoms that maintain their magnetism at a low temperature. Using this compound in a hard drive could lead to a hundred or thousand-fold increase in storage capacity while still keeping the storage device small.

It's apparently an advance in the field of single-molecule magnets and with further research could lead to general applications. Liddle explains: "At this stage it is too early to say where this research might lead, but single-molecule magnets have been the subject of intense study because of their potential applications to make a step change in data storage capacity and realize high-performance computing techniques such as quantum information processing and spintronics."

While it might sound weird to have uranium inside of your computer, the research is using depleted uranium, a by-product of uranium enrichment. It primarily points to a technique that can be researched using similar metals, according to Liddle. Your home office would be safe from a nuclear explosion, probably.

Yeah, in theese times of terrorist scares just who is going to be comfortable with releasing Uranium to the general public.

And dont think like someone who knows that this cant be purified to pure Uranium, think like someone who believes Fox News.

Would be fun if it was an actual Atomic hard drive and that suddenly the hard drive break and a new chernobyl will be created.
...
No actually that would be really bad :O

Still, I don't mind a thousandfold increasement of storage space.
Though I already have enough of 1 terabyte. I don't have that full yet :O

Brings a whole new meaning to rage-quitting.

No need to worry, chemical compounds won't ever give you a nuclear explosion because they are exclusively electron exchanges, sharing, etc. (electrons being outside the nucleus)

Sir, you win this thread and deserve a cookie:

On topic, do we really need that much hard drive space? I mean, a 250 gigger should be good for the average user, 500 seems pretty good for anyone that games or listens to a lot of music, downloads a lot of videos, etc. And if you need more, we have multiple terabytes now. I could see NASA or big businesses using this, but I really don't think the general public has any need of such massive amounts of space.

Now, if only they could get the internet to run at about 1GB per second, I would be happy. Hell, I'd be happy with a quarter of that.

EDIT: Alright, people. I have been quoted plenty of times. I understand that many of you are "computer inclined", or at least know your way around well enough. What I meant was the average user. The average person who uses a computer can turn it on, check his email, rip some music, maybe pirate it, and maybe, maybe install programs. It's possible that I'm severely underestimating "the average user", but my experience as a student help desk worker paints it differently - a lot of those student computers I have to fix are just incredibly simple things that shouldn't even be there to begin with. I'm not complaining because it's given me a job, but still.

As for filling up a terabyte - remember, most people don't rip their DVD's and most people don't have a collection of music hundreds of gigabytes big. To many, that sounds way over the top and impossible to listen to all of it.

So, yes, I understand that terabytes are needed, and plenty of you would probably buy one of these atomic hard drives. But many people just don't need anywhere near that amount of space.

Also, remember when Bill Gates said that "no one should need more than 64 kilobytes of data"? Yeah, that was long before we ripped music and movies to our hard drives. It's a bit different now because, really, how much bigger can we make things like music and movie files?

On the other hand, having about ten times more than you need is better than not having enough.

Can you imagine it though? You're in a heated game online, you're close to winning the big championship for major money, then your dog runs through horny as heck because your female dogs are all in heat, and he rips past you and hits the cord, toppling everything over. Worst yet? That anvil you use for your weekly blacksmithing class is right above, and just as the Uranium-drive tower hits the ground, it falls down and hits it. Boom, you just wiped your entire team, and street, and block... district... city... god that sucks!

Quick! Hate the group of people you can understand the least, and dress up the weirdest! They buy yellow-cake uranium from Chinese child-labor sweatshops and their currency is puppy dog blood!

Tom Goldman:

I find this extraordinarily hard to believe, mostly because there's no such thing as non-radioactive uranium, considering the fact that it has no stable isotope.

Still, a depleted version would be markedly less radioactive, so you could probably encase it in a thin sheet of lead and be perfectly safe.

Yeah, that is shady. Even when it is depleted it is still very radioactive.
So i would not want one of those in my house.
If they wanna use them in server-farms to store data be my guest.
But there is already way too much chemical stuff that is bad for your health
in any household and adding depleted uranium would not help it at all.

An atomic hard drive in lieu with a processor that uses diamonds... I can surely dream.

and after it's released people will slowly develop super-powers which are dictated by their personality, all thanks to Radioactive mutations. sure everyone would look like they just jumped out of a game of Bio Shock with the hideous tumours and all, but doesn't mean a thing when you're invisible right?

Why does this sound like something Aperture Labs would develop. I'm waiting for Cave Johnson to come out with an ad that's something along the lines of:

"Is your hard drive an ancient piece crap? Well don't worry, your buddy Cave's got ya covered. Meet the Aperture Hard Drive, we've used the best atomic science money can buy to give this hard drive 100x the space of your crappy one. Using a special uranium powder there's no limit to how much porn you can stuff in there!" *insert animation of two companion cubes smashing together on a computer screen* "Just so you know Aperture is not responsible for any nuclear disasters you may cause when using your hard drive. Cave doesn't like getting sued."

Has anyone actually seen the video on this very compound on youtube? It is remarkable, what they've done but Steve Liddle himself and Martyn Poliakoff dismiss it due to the fact that it only works between 0 and 2 degrees kelvin.

Here's the video about it: http://www.youtube.com/watch?v=2qZycn7o7Po

Also while you're at it, go ahead and watch everything else Brady Haran has done with the University of Nottingham, you won't regret it :D

What ever happened to memristor technology? Once we get that down, things like drive speed and storage capacity become memories, not concerns. One petabit per cm^3.(A petabit is 1024terabit, or 128TB). This would make the a 2.5in hard drive(laptop size) would be about 6350TB. A 3.5in hard drive would be just under 9000TB(8890TB). Of course, that's actually using a much larger portion of the drives, because swapping out drive plates for non-moving components that don't have current solid state drive problems would be nice.

The largest you could get right now as per the article would be around 400TB for a drive with read time delay. The memristor doesn't have that problem either. Programs would load faster, and with fewer errors.

Of course, with memristors, you can also use them as very efficient computers for data processing. They can be used as transistors, but at much lower voltages(1 to 1.1VDC). This could be used to multiply the battery life of your average laptop by a factor of about 3, unless you used anything that required moving parts. Your systems would stay cooler, run on lower voltages, because they are smaller in size than current semiconductors(3nm vs 25nm).

This just seems to be a stopgap until memristors are brought to market.

its not weapons grade uranium so its impossible to detonate but the radition would be an issue. (most people don't realize that lead shielding only stops some forms of radiation.)

So my case would need 10 feet of lead around it? No thanks, also I don't like the idea of my hard drive having a half life other then the one from valve.

Depleted uranium is a broken down form of uranium into the highest stable atomic structure it can be, which is lead, except with a couple of extra subatomic particles in it for extra mass.

Don't worry people, a 3 molecule thick collection of depleted uranium isn't going to do much to the background level of any room, especially encased in a hard drive mount, in a hard drive. It sure as hell isn't going to melt down, burn through your computer, and become a pile of radioactive slag.

excellent good sir!

so umm how many rads to i get if i open it

This plus quantum computing equals greatest computer ever developed by mankind.

Does it have 92 protons? No? Then it's no longer uranium, end of story. It might be a different, stable isotope of lead, but it's the number of protons that dictates the species of an element.

silverdragon9:

Well, it has the potential to stop all of it, but the scale you would need could get pretty high, but I think going too far into Heisenberg's Uncertainty Principle when talking about deflecting individual neutrons might be a bit excessive for the average reader here.

The difference between what's called depleted uranium and "regular" lead is nothing more than leftover neutrons from fission. I'm pretty sure we can reach agreement there.

Oh no, my computer is overheating! I have to shut it off before-*Atomic Blast*

OT: This seems like a dumb idea... but if they can find a way on how to handle Uranium properly, then I think we should go for it.

you need a TINFOIL HAT! My friend. Also a physics lesson.

That said, this product will never reach market, because for everyone willing to ride the edge of SCIENCE! we're gunna have millions of detractors worrying that our Depleted Uranium hardrives are going to nuke baby jesus. And FauxNews.

Maybe they'd do better if they said it was made from 'UnUranium!', no lemon scented kneejerking with UnUranium!

As long as it doesn't affect my balls, I'll take two.

That was enlightening, as per the fact that this would only work at -2 Kelvin. Not F or C, K.

I imagined this in Cave's voice. I'm not sure when I'll stop laughing.

Yes, but I still think it's a bit disingenuous to call it 'uranium' and not its proper nuclear annotation, Lead-207(or whatever it is).

to be fair though, you can already buy Uranium online.

-2 Kelvin, so it will never work. That's interesting. You should have said below 2 Kelvin, which is different from an impossible number.

I'll leave the tinfoil hats to Americans.
On the physics side you are prolly right, i could have studied more.
And about the depleted uranium. Yes, most of what i know of it comes from the info i have
read on the depleted uranium rouds used by military in Iraq and other war-zones. And the
way it is used there does cause radiation, mainly because they do use other agents that burn at high temperature and thus release the uranium particles that actaully are very unhealthy.

So yeah, that is my reasoning behind it.
I do not want any uranium in my house, even if it would be available one day.
And if that makes me worthy of a tinfoil hat then so be it. I can live with it.
