Russia launched the world’s first floating nuclear power plant on Saturday. The 70-megawatt vessel, christened the Akademik Lomonosov, was towed away from St. Petersburg by two boats. It is currently coasting through the Baltic Sea to the town of Murmansk for fuel, and is then supposed to embark for the Arctic town of Pevek in 2019, according to a release from the state-run firm that built the rig.
