12.8 Petabytes, You Say?

MadUndergrad writes "Dr. Jonathan Spanier from Drexel University has come up with a novel way to greatly increase data storage density: water. Specifically, they propose using hydroxyl ions to stabilize minute ferroelectric wires. These wires could be many times smaller than what is possible today, enabling data densities in the neighborhood of 12-13 PB per cubic centimeter. While there are still many problems to be resolved before drives using these can be manufactured this technology does seem promising. For one thing, it would be non-volatile, but could apparently be made to act as RAM. The fact that this is coming out of a university gives me hope that this technology won't turn out to be just so much vapor."

Oblig. Dexter's Laboratory Joke:

[TripMaster Monkey]

A physics professor and his assistant are working on liberating negatively charged hydroxyl ions, when all of a sudden, the assistant says, "Wait, Professor! What if the salicylic acids do not accept the hydroxyl ions?" And the professor responds, "That's no hydroxyl ion! That's my wife!"

DMHO is deadly!

[spun]

I can't believe they would be so irresponsible as to use dihydrogen monoxide for data storage. That stuff is deadly!

University

[linuxwrangler]

The fact that this is coming out of a university gives me hope that this technology won't turn out to be just so much vapor.

Like Pons & Fleishman's cold fusion? Like the recent Korean cloning fiasco? Like the forestry research papers that were pulled because of political and corporate pressure? Like so many others that have been in the recent news?

Problem is that scientists and researchers can be corrupted by fame, fortune or pressure just like other humans.

I'm not saying that this technology is bogus - I know nothing about the technology or the people involved. But the fact that it comes from a university doesn't offer any special guarantees in my book.

100 Millenia of Data

[digitaldc]

Imagine an iPod playing music for 100 millennia without repeating a single song

Thats great until during that 100 millenia you encounter the next Ice Age, it freezes stopping its data transfer to only playing one song, "I Got You Babe" by Sonny & Cher
  - for eternity.

Hey Clippy, I forgot what I

[JohnnyGTO]

called that spreadsheet!!



User: Hey Clippy search for .xls files containing "2006 budget"

Clippy: I see, you want me to spend the rest of eternity searching 13 petabytes for your stupid spreadsheet??! I quit!! User: This maybe the first effective way to get rid of that little twerp.

Bad physics

[Anonymous Coward]

Without commenting on the competence of the researcher, whoever wrote the press release doesn't have the first idea what they're talking about.

"Ferroelectric materials possess spontaneous and reversible electric dipole moments. These dipole moments are times when the material gains a charge, in this case an electric one. For example, the Earth's magnetic field generates a dipole moment that causes compasses to face north"

First sentence is correct. Second sentence is baloney. A dipole moment is not anything to do with time, and an electric dipole moment does not mean a material gains a net charge, although it might correspond to a charge developing on a certain surface. Third sentence: the dipole moments associated with the earth's magnetization are nothing to do with the dipole moments in a ferroelectric material. The former are the result of intrinsic magnetic moments in atoms, the latter the result of differing charge distributions in materials. Similar names, completely different things.

Mod parent up +5 It does make sense!!!!!

Here is the exact text:

-Joke from Dexter's Laboratory

I've always wanted to understand this joke, from many years ago. @___@;;;
I was reminded of this joke today when we talked about hydroxyls in biology and chemistry. :XD:

To liberate is to set free. The point of this joke is that it's saying that a negatively charged hydroxyl ion is equivalent to a professor's wife. Hydroxyls, which contain at least one hydroxide (-OH), are alcohols. Does the joke mean the wife is drunk?
I then researched salicyclic acids and I found out that salicyclic acid is a plant hormone used as a medicine for acne. More importantly, it is a carboxylic acid. We learned in biology today that an ester linkage is formed between a carboxyl and a hydroxyl, and in this case, salicylic acid and hydroxyl ions create aspirin, the pain reliever.
Now isn't that cool? :D
Lastly, the hydroxyl ion is NEGATIVELY charged, so the wife has had an excess of alcohol.
Basically, therefore, the professor was only trying to give some aspirin to his wife, who has a hangover.
ROTFLMAO.

Btw... I find it creepy that googling this returned six results.

Um... the fact that this is coming from a university suggests to ME that it might be highly impractical, but of some academic interest.

I fully agree. Having spent the last two years working in a business incubator associated with a major research university, I found the following life cycle of new technologies to be true in 95% of cases:

1. Invent something, file an invention disclosure with the university and ask for patenting the idea.
2. File for all grants you can get.
3. Once you run out of grants, declare your intention to commercialize the technology.
4. Secure some start-up funding, primarily in the form of SBIR/STTR grants and angel funding.
5. Once funding is received, declare that the technology is not yet ready and go back to the lab to write more papers on your technology.
6. Repeat and rinse.

I've seen some really ground-breaking technologies in action. One was proven to decrease the level of emissions by 95%. Another promised to replace current heat sinks with a new design that would eliminate computer fans. Yet another has been around since the 1950s; the lead researcher has invented when he was a grad student. Unfortunately, most researchers at the school I was working at were aware of the fact that in the long term having a technology to work on for another decade or more was more lucrative than starting a company and ending with a miniscule ownership share after venture financing.
