TUD presented EASY-A and achieved a record in transmission. They claim its very energy efficient in that the emitter and receiver only need one bit resolution for transmission. The signals use 4GHz bandwith and it took 6.4 seconds for 8 Gigabyte.
one have to admit, that they (still) used cable for transmission, but they’ve designed/created the demonstrator using the concept of their 60 GHz wireless transmission. They estimate about 5 years before this could be used in commercial products.

The Energy superstore is a green blog, which I hope will grow with a lot of useful hints about possibilities for saving our limited ressources. I found them via the doFollowers, a new (beta) directory site. They apply a voting concept with a fresh style of presenting blogs. That said, I don’t see a real value for the premium service, at least at the moment, but wish both the best.

Barabasilab offers a couple of reserach papers about analyzing complex networks. One recent with the above title uses (anonymous) communication data collected about a years period. A similar approach is taken by the senseable lab of MIT. Even I support and like to read those research, I wonder when equal tools are applied to data with links back to the actual persons data. There exist similar for fun projects for money. wheresisgeorge is a US$$ tracker and provides a list of links to other currency trackers

Australia’s Center for Ultrahigh-bandwidth Devices for Optical Systems explain in a research paper how they want to achive 640 Gb/s with all optical signal processing

Maybe this comes as a rescue to united states speed trap

update: startdate is now official at 10′th September

have a look at the current cooldown status. 96 tonnes of liquid helium is needed to maintain the 1.9K temperature required for superconductors. I recently read that this is aside all other things also a new record, until now most experiments only need “a spoon full” of helium for their experiments.
Keep going I’ll keep my eye on this for sure

TUM (technical university munich) created a system to detect toxic elements induced into rivers. It uses biosensors from Cellasys and for instant notification a mobile handset is used.
Researchers of the Fraunhofer-Institut für Solare Energiesysteme (ISE) set a new record in electrical efficiency (6.7 %) for Solar energy generation using fluorescence collectors. They use coloured platters to redirect light to solarcells sitting at the border. another step to outside surfaces being used more efficient.
And Osram announced a new record in luminance and eeficency with white LED’s. in standard environment, they achieved with 350 Milliampere (mA) 136 Lumen per Watt (lm/W). These are the results of combining recent advances of the material and technlogy departments. 500 Lumen is the outcome when using 1.4 ampere. This could be a solution for streetlights, as a recent study of TU Darmstadt revealed that it costs about 760 Miollion Euro each year. And by switching to LED technology we could save about 400 Million Euro, not to mention the savings of 1.6 Million tons of CO2.

Scilife, a new platform for scientist was created recently.
