Renewable Energy: The Power of Salt

August 26, 2014 4:27 pm | by Jennifer Chu, MIT | News | Comments

Where the river meets the sea, there is the potential to harness a significant amount of renewable energy, according to a team of mechanical engineers at MIT. The researchers evaluated an emerging method of power generation called pressure retarded osmosis, in which two streams of different salinity are mixed to produce energy. In principle, a PRO system would take in river water and seawater on either side of a semi-permeable membrane.

A Supercomputer with Warm Water. How Cool is That?

June 18, 2014 12:24 pm | by Peter ffoulkes, 451 Research | Blogs | Comments

An energy efficient supercomputer with warm water.  How cool is that? Enlightenment has long been the ultimate pursuit of artists, philosophers, scientists, theologians and other sentient minds. Whether it is delivering the proof to support their theses, or to investigate a perplexing problem before them, they have poured a vast amount of energy into the situation. Energy has now become the problem.

Is Your Computer Thirsty?

April 4, 2014 10:48 am | by Rob Farber | Articles | Comments

Ahhh! There is nothing like a tall, cool drink of water when thirsty. Not surprisingly, computers also prefer liquid refreshment as opposed to air cooling when hot. The choice for the technologist resides in when to make the move to liquid cooling and in what type of liquid cooling system is most appropriate.

Power and Cooling: The Sword of Damocles?

April 4, 2014 10:38 am | by Steve Conway | Articles | Comments

Fifteen years ago, power and cooling didn’t make the top 10 list of issues HPC data centers were facing. That changed quickly with the rise to dominance of clusters and other highly parallel computer architectures, starting in the period 2000 to 2001 and escalating from there. In IDC’s worldwide surveys since 2006, power and cooling have consistently ranked as the number two concern for HPC data centers

Supercomputers Capture Turbulence in the Solar Wind, could Help Forecast Destructive Space Weather

December 17, 2013 9:20 am | by Lawrence Berkeley National Laboratory | News | Comments

During particularly intense solar storms the magnetosphere can “crack,” allowing charged particles to seep in and wreak havoc on the Earth’s technological infrastructure — an event called space weather.  Scientists currently do not have the ability to accurately predict the severity of a space weather event or where it will have the most impact. But researchers are hoping to change that.
