Google data centers process an average of 40 million searches per second , resulting in 3.5 billion searches per day and 1.2 trillion searches per year. Google was spending $20 billion per year on its data centers in 2014 and now is spending about $30 billion per year. Google used 5.7 terawatt-hours of electricity Google consumed in 2015 which is about 1 gigawatt of power. If each server used 200 watts then Google had 5 million servers in 2015. In 2017, Google power usage has likely continued to increase and Google has some very energy efficient servers. It is highly likely that Google has over ten million servers. Google’s global data centers have been using atomic clocks for database synchronization for close to ten years. The Spanner project was revealed over five years ago. Google began the spanner project over ten years ago. The Spanner database uses atomic clocks and GPS for transaction timing.

Russia will start building multi-purpose  nuclear-powered submarines  of the fifth generation in 2020. Companies of the United Shipbuilding Corporation (USC) are ready to start the work in 2020, when 885 Yasen project is completed. The Russian Husky submarine will be the follow up to the Yasen submarine. The new submarines will be smaller and cheaper than their Soviet-designed predecessors. Indeed, there are indications that Moscow will be extensively leveraging automation technologies developed for the Project 705 Lira-class attack submarine—better known in the West as the Alfa-class—for the new boats. Russian analysts estimate that the next-generation submarines will displace no more than about 6,000-tons. Which means that another Soviet innovation might make a comeback—liquid metal cooled reactors. Russia will also incorporate  composite structures in its next-generation follow-on to the Project 855M Yasen-class  in the 2020s. The next-generation Russian nuclear ...
