Thanks to a BBC programme, Costing the Earth, I just heard about Desertec, a proposal to provide 10-25% of Europe’s electricity via solar power panels in the deserts of North Africa. What I thought was particularly impressive is the claim that the solar panels could provide a three-fold benefit for these African nations. They’d sell the power, of course, but they would also get desalinated water (because this is needed to run the power plants) and they could grow crops in the shade of the giant mirrors! I always thought that the problem with remote electricity generation like this would be the losses in transmission over long distances but the people behind this concept claim that by using High Voltage Direct Current (HVDC) these losses would only amount to 10-15% of the power generated.

I have no idea whether this would be feasible, technically, politically or economically, (one critic says it would cost 0.15-0.20 euros per KWh - about double what we pay for power currently) but it sure sounds appealing on the face of it.

(Well, my computer is). A little while ago I heard about Malariacontrol.net, part of the Africa@home project. You download an application (the Berkeley Open Infrastructure for Network Computing - Boinc - available on PC, Mac and  Linux) and instead of donating spare processing power to the quixotic search for extraterrestrial life you can use your computer (when it is turned on but not doing anything else) to help scientists better understand how malaria spreads. Or at least you could until recently - at the moment they have all the computers they need for that project. But keep revisiting Africa@Home as they plan to publicise more projects soon. Meanwhile there are several other projects that use Boinc.

It seems that while processor speeds are accellerating so are electrical power requirements - at least for servers. This is starting to worry one Google engineer. I had no idea that, for low-end servers, “If we assume a base energy cost of nine cents per kilowatt hour and a four-year server lifecycle, the energy costs of that system today would already be more than 40 percent of the hardware costs.” I had the impression thanks to EnergyStar and similar programmes that overall power consumption was going down on PCs. I guess/hope Google’s servers (which are on all the time, presumably working at full speed and not built to minimise power consumption like laptops) are unusually power-hungry.

New Scientist magazine - a weekly magazine of science news - a bit like The Economist or Prospect magazine for the scientifically-minded - has recently launched a weekly 12 minute Podcast - a great way to catch up on what’s going on in science while you are driving (or cycling!).

I used to be the magazine’s Net Editor ten years ago (!) and I am pleased to see that it is still keeping abreast of the latest Internet trends…

A ’smart bag’ that tells you when you’ve forgotten something. It’s one of several ’smart fabric’ applications that have been explored in the bYOB (build your own bag) project at the Media Lab. This kind of thing has been discussed for many years now. I hope they stop talking about them and start marketing them soon - I’m always worrying I’ve left stuff behind when I’m packing.

Toshiba (which makes nuclear power plants as well as laptops - who knew?) has offered to give an Alaskan village a ‘mini-nuke’. It seems they’ll take it - after all it will reduce their cost per kilowatt/hr from 28 to 10 cents (they only pay the running costs). At the moment they get all their power from diesel which has to be barged in during the ice-free months…

(see also “my earlier posting”:http://blog.org/archives/cat_positive_uses_of_technology.html#001340 on nuclear power).

The Guardian (back in April) took a peek at the Librie EBR-1000EP which costs c. 220 pounds (only available in Japan at the moment) and sports a 6in screen with a resolution of 600×800 dots at 170dpi, (better than the 70-90dpi of a regular computer display). It’s using the microcapsule display technology pioneered by “E Ink”:http://www.eink.com/ working with Sony and others.

It’s potentially a very exciting development - it’s a pity that according to “a recent review in Fortune magazine”:http://www.fortune.com/fortune/peterlewis/0,15704,685443-1,00.html Sony predictably enough married this potentially revolutionary technology to a boneheaded copy protection scheme.

The Guardian has a new weekly “Improbable Research column”:http://education.guardian.co.uk/higher/research/improbable which is introduced by the hyper-active editor of the “AIR”:http://www.improbable.com/, Marc Abrahams (he gives a potted history of his involvement in the first column). So now there’s a “paper magazine”:http://www.improbable.com/navstrip/subscribe.html a “website”:http://www.improbable.com/ the “Guardian column”:http://education.guardian.co.uk/higher/research/improbable and, of course, a “weblog”:http://improbable.typepad.com/, all dedicated to the discussion of amusing stories to do with the stranger reaches of the pursuit of science.

And if you like that you might also take a look at “Feedback”:http://www.newscientist.com/opinion/opfeedback.jsp;jsessionid=DJEHNEAGEIKH?id=ns244999 from a fine magazine I used to work on - “New Scientist”:http://www.newscientist.com/.

It still doesn’t work too well. “Only 7.4 percent of online consumers who noticed these systems said they often purchased recommended products, according to a report issued in February by Forrester Research. About 22 percent said they found the recommendations valuable, and about 42 percent said the products listed were not of interest.”

I posted about a Wall Street Journal article on this subject earlier which pointed out such problems can be not just annoying but dangerous.movies view pay permovies pedomovie the poison ivyreality movie teensample shemale moviemovies sapphic extasysapphic incest moviesmovie shemale trailersstreet racing movieshardcore teen movies freeringtone 2.99index ringtones polyphonic 3510iringtone blackberry download 7100itaste a of ringtones honey6256i ringtone nokiaa680 ringtonesmyx free ringtone sagem 2nokia free 3570 ringtone cricket Map

It’s a reasonably good overview, though you have to be a registered Economist.com or Economist subscriber to read it. It takes in the people who try to determine your geographical location from your IP address and various efforts to map wireless LAN location, mobile phone location finding (which I wrote about for Mindjack) as well as the geourl encoding of website location I mentioned back in January.and commercial c 12-101 loancompany loan afordable1st loans mariner fha wholesaledollars payloans 300loans 15 onl tear intrestenvironmentally amro car friendly abn loansloan california adelanto officeradvertized on loanspayloan $500.00 loanstudent loan deductions 1098t and
