From ballast water savings, Urke delves into his new “power-generation” system, saying without pause that 1,300 kW of waste energy can be converted into 150 kW of residual electric power using his system. “The ef? ciency isn’t good, but the (alternative) is to waste it.”

Meanwhile, the waste energy on a 240
