The EcoGeek Newsletter has been missing for the past few weeks as many of you have noticed.  We have been sorting out some technical issues, and this is the first trial run of the new Newsletter, so let us know about any problems you have with the new system.  Thanks for your patience while we've worked through this.  We will continue to bring you exciting updates and the latest stories from EcoGeek.


Computer Energy Efficiency Doubles Every 18 Months


A new study done by an engineering professor at Stanford University has found that the energy efficiency of computers doubles roughly every 18 months, and has done so since the very first general purpose computer, the Electronic Numerical Integrator and Computer (ENIAC) that was built in 1956.

 

New York City Bike Share Program Will Have 10,000 Bikes, 600 Stations

Last year, we heard that New York City was considering a huge bike sharing program and now it's becoming a reality. New details have been released about the program and it's just as big as had been hoped. There will be about 600 stations with 10,000 bikes and the program could be up and running by next summer.
 

Hoverbarge Allows Difficult Access Construction

As wind energy developers continue to develop new locations, there are many instances where site access is particularly difficult because of swampy conditions, or the location is in a tidal zone, or is otherwise difficult for more conventional access. To make access to these sites possible, Hovertrans Solutions Pvt. Ltd. has a vessel called a hoverbarge.
 

Cleaning Uranium Contamination with Bacteria

Bacteria may be a key in containing radioactive contamination and other environmental pollutants. A naturally occurring bacteria found in soil called Geobacter has been known to be useful in contaminated soil cleanup, but the process by which it prevents the spread of pollutants has not been known until the work of Gemma Reguera and her team of researchers at Michigan State University identified how the the bacteria concentrates contaminants.
