Another tip o' the hat to gCaptain - this article about Rolls-Royce's new line of LNG-powered prime movers. Given the growing presence of natural gas and LNG in the marine world, this is a great thing to be on top of. Even Tier 3 engines put out significant pollutants, though things are much better than they were twenty years ago.
