Calysta says that in contrast to current algae- and sugar-based methods, a methane-based biofuel platform is expected to produce fuel at less than half the cost of other biological methods, allowing direct competition with petroleum-based fuels. One of the most surprising outcomes of the project, Ward et al. capsulatus. PathwayGPS.

The unthrottled nature of the compression ignition process provides high engine efficiency while achieving compliant exhaust emissions with conventional, low-cost aftertreatment. This—in addition to the opposed engine architecture—could increase fuel efficiency by 40-50% over the comparable spark-ignited gasoline engine, Achates said.

In 2004 Barroso was tasked with investigating ways to build more efficient data centers. He devised a way to use low-cost components and energy-saving techniques to distribute Google’s programs across thousands of servers, instead of the traditional method of relying on a few powerful, expensive machines.
