New Battery Technology

Everything these days seem to run on batteries! Now, MIT has made a breakthrough in a new type of battery that could change everything!

New Battery Technology

“Joel E. Schindall, the Bernard Gordon Professor of Electrical Engineering and Computer Science (EECS) and associate director of the Laboratory for Electromagnetic and Electronic Systems; John G. Kassakian, EECS professor and director of LEES; and Ph.D. candidate Riccardo Signorelli are using nanotube structures to improve on an energy storage device called an ultracapacitor.

Capacitors store energy as an electrical field, making them more efficient than standard batteries, which get their energy from chemical reactions. Ultracapacitors are capacitor-based storage cells that provide quick, massive bursts of instant energy. They are sometimes used in fuel-cell vehicles to provide an extra burst for accelerating into traffic and climbing hills.

However, ultracapacitors need to be much larger than batteries to hold the same charge.

The LEES invention would increase the storage capacity of existing commercial ultracapacitors by storing electrical fields at the atomic level.”

Why “Bring Home the Bacon,” When You Can Print It?

Uh… yeah. This is weird. I know ink jet printers can do a lot of things… but come on! (Maybe it is a new diet craze?!?)

Printing Meat for fun and profit?

“Tissue engineers like Vladimir Mironov of the Medical University of South Carolina, and Thomas Boland of Clemson University, have been printing biomaterials with modified ink-jet printers.

The cartridges are washed out and refilled with suspensions of living cells; the software that controls the characteristics of the ink is reprogrammed and you’re good to go. Boland and Mironov use layers of “thermo-reversable” gel to build up three-dimensional structures like tubes—capillaries, to use the medical term. When the tiny droplets, or clumps, of cells came together closely, they fused; the gel can be easily removed, leaving a tube of tissue.

Just as printers contain inks of different colors, so tissue printers could contain different cell types to create complex structures.

Now, it seems to me that a tube or complex living organ is a pretty complicated structure. Why not practice with a simpler, more two-dimensional form of muscle tissue—like bacon, for instance? Nothing like fresh bacon.”

Uhhhhh… yum.

It really is Podcast Number 22… not 21! I got it wrong in the Podcast itself… drat! Talk about the Nyxem virus that exploded on Feb. 3rd… virus nastiness and virus signatures, download free AVG antivirus, make your Windows XP PC look like a Mac (if you must!), Phone spoofing as a business??? Kevin Mitnick joins the Jedi?, more details on the Nyxem virus and all file types it deletes, explanation of DBAN, our Geek Software of the Week, and how it works… warning: it WILL destroy your hard drive data! Review (in a manner of speaking) of Dragon Naturally Speaking Version 8.1 (It rocks!) Big News!!! Dr. Bill the Podcast is now a proud member of the Techpodcasts Network! Yay! Rejoice with the Doctor! Dr. Bill reflects on being a bum… kinda. Bye!

Geek Software of the Week: DBAN

Have you ever sold or donated a PC to someone else? Have you considered that even if you “delete” your private data, it is still recoverable? So, your data COULD be retrieved and used to get into your bank account, etc.! You need a way to totally ZAP your data! Well, here you go!

Darik’s Boot and Nuke

“Darik’s Boot and Nuke (‘DBAN’) is a self-contained boot floppy that securely wipes the hard disks of most computers. DBAN will automatically and completely delete the contents of any hard disk that it can detect, which makes it an appropriate utility for bulk or emergency data destruction.”

DBAN comes in a floppy and CD-ROM version. And, of course, it is totally FREE!

PLEASE NOTE: As Darkmoon points out in a comment to this post, there is NO “CONFIRM” option, once you choose to wipe your drive with DBAN, it will just WIPE IT! And, there is no return from this! Your data will be GONE! You have been warned! Don’t come crying to the Doctor! [Grin!]

By the way, if you are looking for a utility to simply delete files securely, WITHOUT wiping the hard drive, check out simple File Shredder available here:

Eraser

Will February 3rd Rock Your Computer World?

Why February 3rd? Well, that is the day the Nyxem virus is supposed to “go off.”

Nyxem Virus Set to Destroy on Feb. 3rd

“On that date the Nyxem virus is set to delete Word, Powerpoint, Excel and Acrobat files on infected machines.

Nyxem is thought to have caught out many people by promising porn to those who open the attachments on e-mail messages carrying the virus.

Anti-virus companies have stopped lots of copies, suggesting it had infected a large number of computers.”

Files that will be deleted on infected systems are:
DMP – Oracle files
DOC – Word document
MDB – Microsoft Access
MDE – Microsoft Access/Office
PDF – Adobe Acrobat
PPS – PowerPoint slideshow
PPT – PowerPoint
PSD – Photoshop
RAR – Compressed archive
XLS – Excel spreadsheet
ZIP – Compressed file

So, be sure your virus signatures are up to date and hold on tight!

Phone Spoofing as a Business

OK, so Kevin Mitnick and the like made phone spoofing “cool.” What is “phone spoofing,” you ask? Well, you can make a call, while appearing to be another caller (another line) and even charge it to that line. Now, you can do that AND change your voice to sound different as well… and it is a BUSINESS!

SpoofCard

What is the world coming to? What possible purpose (ligit, that is) could it serve?

Geek Software of the Week: Naomi – Internet Blocking Software, WINE and recursive acronyms, Yahoo gives up on Search Engine dominance, Red Hat to release Red Hat Linux for MacBook Pro – why?, with lot’s of time left on the podcast… Dr. Bill reads ACTUAL warning labels from common objects. Can you stand it?!
