Imagine the possibilities of harvesting waste heat and converting it
into electricity. Computer processors could be the source of power for
their own cooling devices and solar cells could become dramatically
more efficient by leveraging energy that is not being used today. If
everything goes right, nanoantennas could even replace solar cells one
day, researchers believe.
Rentech, a company that turns hydrocarbons such as coal and natural gas
into alternative fuels, says it has begun producing an “ultra clean
synthetic fuel”. The process is controversial, especially because coal,
which is capable of emitting significant amounts of carbon dioxide when
combusted, is involved.
The secret that allows objects to become completely invisible to the
human eye has been one of the big quests of science, but remains a
mystery can only be achieved through special effects in science-fiction
movies. U.S. researchers now were able to actually build and define the
first 3D cloaking device that can, in a limited way, achieve 3D
When it comes to convention badges, Defcon
certainly takes first place. This year’s badge is practically studded
with blinking LED lights, batteries and even an SD card reader. As
always, attendees are encouraged to hack the badge and the best
contraption will win prizes.
Pricewatch – HD DVD players are gone for almost half a year and the
victorious Blu-ray format is plugging along, but there seems to be few
convincing incentives for consumers to actually make the jump to the
high-def format. Average retail prices are falling and have broken
through the $400 barrier. The next barrier is $300 and it seems that
most companies believe that a price of or around $300 is about right at
Interview – Lots of graphics tech tradeshows are on the calendar for
the coming weeks - Siggraph 2008 in Anaheim, IDF Fall in San Francisco,
Games Convention in Leipzig and Nvision 08 in San Jose. Intel will play
a big role in three of those shows and with Larrabee out and Nehalem
almost ready for showtime, we felt it was time to get an update on
Intel’s ray-tracing efforts.
This morning Dell announced the company has achieved its goal of carbon
neutrality in less than a year’s time and five months ahead of their
schedule. Dell has done this by using a combination of methods ranging
from energy efficiency, carbon offsets from rainforest preservation in
Madagascar and voluntary green power purchases. The program was
designed to help eliminate or offset 475,000 tons of carbon dioxide
Scientists are gearing up to launch the Large Hadron Collider (LHC) a
17-mile long particle accelerator that debuts with the promise to
enable science to look deep into the origins of the universe, providing
new insights in matter, space and time. The LHC may very well be the
most fascinating science project of our generation.
How often have you heard the word “cloud” this week? We tend to believe
that you should hear this word at least once a day, if you consider
yourself an informed computer user. Following cloud computing devices,
legal questions, various cloud computing projects of industry giants,
we are also hearing more and more about possible services – services
that may offer value and convince users to subscribe to cloud services.
One of most convincing services we have seen so far is CloudAV, a
project developed at the University of Michigan.
Big U.S. transportation companies are obviously hearing the noise
coming from T. Boone Pickens’ campaign. Larry Burns, GM vice president
of research and development, recently revealed on the company’s blog
that GM has taken a positive stance in regards to the utilization of
natural gas for vehicles. This comes as a surprise, considering the
fact that GM has been pushing biofuels and their Volt program a lot
more than they have made any decisions or had any major discussions
regarding natural gas vehicles.
