Hotel guests pedal for their supper

By - April 18, 2010 1 Picture
If you find yourself in an expensive hotel without the funds to cover that three-course seafood buffet you've just demolished, you may not be led to the back of the kitchen to scrub pots and pans after all... you could be off to the gym instead. Crowne Plaza Copenhagen Towers has installed two electricity-producing bicycles which are connected to the hotel's main electricity supply. Guests who pedal hard enough not only get a dose of environmental feel-goodness, but can also score a complimentary meal. Read More

Breakthrough in using sunlight to split water

By - April 16, 2010 2 Pictures
A team of MIT researchers has managed to mimic the photosynthetic process in plants by engineering M13, a simple and harmless virus, to help splitting water into its two atomic components, hydrogen and oxygen, using sunlight. The researchers hope this is the first step toward using sunlight to create hydrogen reserves that could then be used to generate electricity or even produce liquid fuels for transportation.

Internet could lower its cooling bills by using hot water

By - April 16, 2010 4 Pictures
It’s easy to think of the Internet as something that’s just “out there” in cyberspace, that doesn’t effect the physical world in any tangible way. In 2009, however, it was estimated that Internet data centers worldwide consumed about 2% of global electricity production. Not only did most of that electricity undoubtedly come from non-green sources, but it also cost the global economy approximately 30 billion US dollars. Much of the electricity was needed to power the data centers’ forced air cooling systems, that keep the servers from overheating. Now, researchers from IBM Zurich and the Swiss Federal Institute of Technology Zurich (ETH) have devised a much more efficient method for cooling the steamy Internet - they use hot water. Read More

Robonaut 2 headed for orbit

By - April 16, 2010 3 Pictures
For decades boys and girls have dreamed of becoming astronauts when they grow up. Now young assembly-line robots and claw vending machines can share the same dream with news that NASA plans to send Robonaut 2 (R2) into space. R2 will be the first human-like robot in space when it is launched on the shuttle Discovery later this year to become a permanent resident of the International Space Station (ISS). Read More

Recovering pricey nanoparticles using oil and water

By - April 16, 2010 1 Picture
Nanoparticles may be small, but they sure ain’t cheap - ounce for ounce some of them are more precious than gold. Which is why scientists are seeking better ways to recover, recycle, and reuse the tiny particles that are barely 1/50,000th the width of a human hair. A new method to recover these valuable specks using a special type of microemulsion may make such recovery efforts easier and speed the application of nanotechnology in a variety of fields. Read More

Nothing negative about cheaper treatment for open wounds

By - April 15, 2010 2 Pictures
For some reason, and nobody knows exactly why, the healing process for open wounds can be sped up by applying suction to them under a tightly-sealed bandage. The negative pressure this creates has been benefiting patients for decades but because mechanical pumps are expensive and they need a constant electricity supply the technology is not readily available, often where it is needed most – in the developing world. A newly developed basic negative pressure pump that doesn’t require electricity, is cheap to manufacture, lightweight to transport and can be left in place for days could change that. Read More
