Submission + - Hydrogen turbines generate clean electricity

Submitted by
Roland Piquepaille
Roland Piquepaille writes: "The Lawrence Berkeley National Laboratory (LBL) has developed near-zero-emission gas turbines using pure hydrogen as a fuel. But because this LSI (low-swirl injector) technology also can use other fuels, it has the potential to help eliminate millions of tons of carbon dioxide and thousands of tons of nitrous oxides (NOx) from power plants each year. In fact, burners with the LSI emit 2 parts per million of NOx, more than five times less than conventional burners. The multi-patented technology is currently available for licensing. I sure hope that a utility company will be interested. But read more for many additional references and photographs comparing a high-swirl injector (HIS) and a low-swirl injector (LSI)."

Data Storage

Submission + - UCF Researcher develops DVD which holds 1 Terabyte

Submitted by Miti
Miti writes: University of Central Florida Chemistry Professor Kevin D. Belfield and his team have developed a new technology that will allow users to record and store massive amounts of data around 1 Terabyte on a single DVD like disc reports Newlaunches. Belfield's Two-Photon 3-D Optical Data Storage system involves shooting two different wavelengths of light onto the recording surface. The use of two lasers creates a very specific image that is sharper than what current techniques can render. Depending on the color (wavelength) of the light, information is written onto a disk. The information is highly compacted, so the disk isn't much thicker. It's like a typical DVD. The challenge scientists faced for years was that light is also used to read the information. The light couldn't distinguish between reading and writing, so it would destroy the recorded information. Belfield's team developed a way to use light tuned to specific colors or wavelengths to allow information that a user wants to keep to stay intact.

Submission + - The next notebook battery? Lithium polymer

Submitted by Lewis Clarke
Lewis Clarke writes: Looks like after the laptop battery fire fiasco, Sony would be changing its course to use an old technology for its future battery manufacturing. ZDNet reported on Sony Electronics President Stan Glasgow meeting with reporters, where he said that Notebook makers will "likely" soon choose to incorporate lithium polymer batteries (A battery technology that emerged nine years ago) over the current commonly used type, lithium ion batteries. Lithium polymer batteries use lithium as an active ingredient. Lithium is a volatile material, but the lithium in these batteries isn't packed into cells as it is in lithium ion batteries. Instead, it is contained in a polymer gel. These gel batteries can't provide the same sort of energy density as lithium ion batteries but its safe from internal short circuit that set off a chain reaction and start a fire.

Submission + - How does Apple hash passwords to WEP keys?

Submitted by simm1701
simm1701 writes: Does anyone know the details of Apple's WEP password->key hashing algorithm?

My neighbour has gone on holiday but after talking to him via email and mentioning that my ADSL is dead he kindly offered me access to his wireless network which he left running.

Unfortunately his setup is apple and he only knows the password, not the hex key that Apple hashes this to. Sure Apple has a solution for this which is to log into the base station (which you have to be connected to, ie either by wire or be on a mac, or already know the key which you are trying to find out) and the base station will display the network equivalent key on request.

I always thought that showing a key/password on screen was a bad idea — so does anyone know of an application into which you can enter the password and it will hash it to the key in the same way that apple does? Or does anyone know of the algorithm used so I can code it myself?

Please no discussion on the benefits of moving to WPA — I agree with them all completely, unfortunatly some of the older apple hardware (which my neighbour has) will only work with WEP.

Submission + - Locating a server in your home

Submitted by
An anonymous reader writes: It's going to be 41 degrees C here tomorrow. At the moment my server (with 5 hard disks) is located temporarily in a room on it's own, mostly because no one wants to be in the same room as all those fans and disk motors. This is not a wise allocation of limited house space :-} (Yes — you guessed it — I am single) Q: Where do folks locate their servers in suburban homes? Q: Whats your best tricks and tips for making that server more house friendly? I am thinking about security, heat, noise, space, access...I guess in cooler climates any cupboard will do....

Submission + - Google Blinks - Responds to AdWords Accusations

Submitted by Anonymous Coward
An anonymous reader writes: Based on the thoroughness of the statement and the use of the word "precedent" in the second sentence, it appears that the Google PR team huddled with the legal team and issued a statement on the Inside AdWords Blog.
"...it seems that the underlying issue here is Google's lack of transparency which is a recurring theme in how it runs its business."

Firefly MMORPG Announced 309

Posted by CowboyNeal from the space-ships-and-capes dept.
bishiraver writes "Multiverse has announced that they have gained rights to a Firefly Massively Multiplayer Online Game. Multiverse is a company started by several former Netscape employees, and they have developed an engine/network that works for all of their games. They intend to break into the MMO industry by being an MMO publisher of sorts. By standardizing, they can provide a less expensive alternative to the tens of millions of dollars and several years it takes to currently develop an MMO. They have said they will hire out a studio to build the game for them. Corey Bridgets, Massive's Executive Producer, says: 'If you're doing science fiction, you have to really think it out and create an incredibly rich environment that is compelling in its own right, and worth exploring and going back to week after week. That's what Joss Whedon did with Firefly.'"
