Google Ends a Renewable Research Project

Google is renowned (and sometimes ridiculed) for its willingness to allow a vast herd of esoteric projects to roam its offices, but inevitably there is a culling. Among several victims announced today: Renewable Energy Cheaper than Coal (RE

On its blog and in a longer post on its website, Google more or less said it had taken the work, which began in 2007, as far as it could. “We’ve reached a point in our engineering projects where we’re facing new challenges related to our solar receiver design,” the company wrote. “At this point, other institutions seem better positioned than Google to take this work to the next level. Therefore, we’ve retired our engineering work on RE

Power tower systems work by assembling an array of mirrors (heliostats) around a tower receiver, where water (or some liquid) is heated, ultimately creating steam to drive a turbine. Plants along these lines are operating in Spain, and BrightSource Energy’s Ivanpah plant now under construction in the California desert – with $168 million in backing from Google – will be the world’s largest when it begins operations in a couple of years.

In addition to passing along its research, the company listed a trio of lessons learned through RE
