0.57% efficient + URL to get free copy of paperPeople say they can't find the paper nor the efficiency values of this solar cell. One of the researchers posted it on the Rutgers University website: http://nanotubes.rutgers.edu/PDFs/C60%20+%20SWNT%
2 0Complex%20OPVs.pdfNotice the energy conversion efficiency is 0.57% and the fabrication process is quite sophisticated, requirng exotic Fullerene chemicals and other sonatic lab gear.
Compare that to a classic Dye-sensitized cell one can make at home with titanium dioxide and rasberry juice... but delivers 0.45% energy efficiency.
The DIY solar cell recipe below achieves nano-level self-assembly with TiO2 instead of bucky balls and outputs 0.43 V and 1 mA/cm2. Titanium Dioxide is very inexpensive because it's most common ingredient used in white pigment. http://www.solideas.com/solrcell/english.html
How useful is this much power? Consider that a cheap Nokia phone requires 3.7 volts at 140, which equates to 0.518 watts of power needed to charge it. That means one of the cells above,no larger than a square foot, could do the job... on a sunny day. http://www.knowprose.com/node/8906
Interesting note that a 14 year old girl won a Discovery Channel Science Award testing one of these home-made TiO2 cells. http://school.discovery.com/sciencefaircentral/dy

Re:And this is news?
The reasonable man adapts himself to the world: The unreasonable one persists in trying to adapt the world to himself. Therefore all progress depends on the unreasonable man. -- George Bernard Shaw

Re:And in the spirit of thingsThe Wise adapts himself to the world. The Fool adapts the world to himself. Therefore, all progress depends on the Fool.
Progress doesn't depend on the foolish. It depends on the unreasonable men and women who refuse to take things at face value and mindless act a certain way "that's the way they've alway been done".
The correct version of your quotation is attributed to George Bernard Shaw. http://knowprose.com/node/12260 It is famous enough, that misquoting it makes *you* look like a fool.

Re:Money Laundering
Kinda like this?

Right Idea, Wrong Tool.
They should be using Inertial Navigation Systems. And Wired should fix it's registration process.

Exploit Information - Drupal
Exploit they used:
"I found out that there's a "new" drupal exploit which allows posters to inject arbitrary code into the system for execution on the server -by way of comments. The Drupal.org site is presently down, and apparently has been last night. If you're running Drupal 4.5.1 or 4.6.2, turn off your comments. For visitors here, I'm sorry that you presently cannot comment and I'll turn them back on as soon as possible."

Sample source code of the exploit:

Red Hat Advanced Server 3.0 powers spreadfirefox.com:
Response Headers - http://www.spreadfirefox.com/
Date: Fri, 15 Jul 2005 20:01:52 GMT
Server: Apache/2.0.52 (Red Hat)
This vulnerability has been known for over 2 weeks. Was there no Redhat patch available or did the admins slack off?
Also, isn't it strange how Drupal gets 2 posts on Slashdot in the same day?

Re:Reality check time
We don't want them in the Caribbean either!
The UN's Development Programme (UNDP)'s Sustainable Development Networking Program (SDNP) supports LUGs around the Caribbean and presumablly, the world.
SCO's next target: the UN? Maybe they'll send a 'peacekeaping' force to Utah? -
Forbes Magazine has more
So far this story doesn't appear to be getting a lot of mainstream press, but Forbes Magazine does cover it in this article. A lobbyist for the MPAA confirms that they had something to do with it, but the MPAA VP denies authorship: "They sought our input. We didn't write the letter." Otherwise there doesn't seem to be much media interest. Not at all surprising.
I wonder how many of Lockyear's words in this DVD decryption case also came out of the mouth of the MPAA.
Side observation:
In the excerpts from the letter, the attorney general uses the term "consumer" 7 times to refer to the general public. He uses the term "citizen" only once, urging the business audience to be "good corporate citizens." Our government increasingly refers to us as "consumers." Apparently they recognize who the actual "citizens" are, whose rights they diligently strive to enforce. -
