Slashback: Pliancy, Antennae, Gobe

Slashback tonight with more words on printable, organic transistors; the off-screen saving-Farscape saga, wireless schools, Gobe Productive, and 802.11 antennae to extend you connection. Read on for the details.

Go be something! Simon Gauvin writes "As a follow up to your article on Gobe Productive, beunited.org is setting up a donation site to allow people to donate for the purchase of the source to make it open. You can check out the comments here. And our announcement on our main page."

Thinner is better. Factomatic writes "The The New York Times reports that a new polymer by Xerox can be used to make organic transistors on a plastic substrate, which can then be used to inexpensively make light, flexible flat-panel displays for computers, laptops and mobile phones. The material, polythiophene, has achieved performance on electronics benchmarks that is an order of magnitude greater than current polymer materials. It would be used in a new manufacturing process that Xerox is experimenting with to imprint circuits using inkjets." You may remember this story about a company called Rolltronics' research into printable circuitry.

What about reviving The A-Team? Julio Ojeda-Zapata points to his Update: 12/10 01:25 GMT by T : [Errr, not "her" -- sorry about that.] "in-depth article on the Save Farscape movement. Though I have an obvious bias, I believe this is the most comprehensive article on the subject you'll find anywhere. Predictably, I've been deluged by mail from Scapers. I can't say I wasn't warned about that :-)"

Soon, every Thomas Aquinas, Dickinson and Harvard will have one of their own ... Amadaeus writes with news of another all-campus wireless blanketing. "The new University of Ontario Institute of Technology is offering new students an IBM laptop, included with tuition, that is wired with 802.11b access. The reason behind that is the entire campus (read: cafeterias, stairwells, washrooms, "special areas") is covered with the university wireless network hubs. In fact, the university campus itself is designed with charging outlets for every seat in the classroom and ergonomic seating for computer usage for all students.

Either they're trying to improve wireless education or promote in-class LAN parties and all-night wireless hack-o-thons, UOIT is on the right track to some sort of wireless educational future."

Wireless Weapons: A mini-Howitzer or a Liberator. We've run several stories on 802.11 antenna projects that require more time, more esoteric parts, or a bigger budget, and some that don't take much at all. Daniel Marsh writes with another one in this last category: "If you thought Pringles were fun, check out the Cookie Cantenna. Several have been built and tested by Seattle Wireless members and they blow Pringles cans out of the water, as well as taste better."

On the other hand, if convenience is more importance than raw power, you might find this commercialized alternative attractive. The Cantenna is inexpensive (19.95 by itself, plus the cost of a pigtail) and means you don't have to touch a soldering iron, glue, or anything besides a shipping container.

Both actions are blaimed on "lack of ratings", but what do you expect when putting a show on on a Friday night. Only nerds have time on Friday... er, oh right. I'm posting this on Slashdot...

      Anyway, I wish more people knew about these two shows because they are far more intelligently written and produced than 90% of the junk that's on TV the rest of the week. Are these shows too intelligent for the average viewer, or is it the sci-fi image that pushes people away? Or is it simply the strange times that these shows are offered (anyone remember Babylon 5 at 11:30 pm if you were lucky)? When will sci-fi get its fair share of good time slots?

The good news is that the sun provides 1KW per square meter energy, but the bad news is you'd be doing good to get a 1% overall efficiency delivered to the end user (due to cell efficency, solar system geometry, weather, storage and conversion losses.) Assuming 1%, you'd need 1000 square meters of cheap plastic seimiconductors for each person to provide for 100% of our energy needs.
