A marine vessel engine in which moving parts found in conventional marine engines are eliminated, wherein such engine is used for the propulsion of marine vessels. In the marine vessel engine, no lubrication or cooling is required, and a column of water replaces the conventional piston in a cylinder of the engine, wherein such water column partially fills such cylinder. The marine vessel engine comprises a cylinder, a bent tube with a plurality of openings and two ends, a flapping member, at least one solenoid valve, and an exhaust. In operation of the marine vessel engine, a column of water fills the cylinder through the bent tube openings, and is purged outside from the cylinder through the flapping member. The at least one solenoid valve controls the flow of a power source into the cylinder.

Systems and methods for separating hydrocarbons on an internal combustion powered vehicle via one or more metal organic frameworks are disclosed. Systems and methods can further include utilizing separated hydrocarbons and exhaust to generate hydrogen gas for use as fuel. In one aspect, a method for separating hydrocarbons can include contacting a first component containing a first metal organic framework with a flow of hydrocarbons and separating hydrocarbons by size. In certain embodiments, the hydrocarbons can include alkanes.
