Lyatkher proposes and describes new technologies for the cost-effective conversion of tidal and river power into electricity. The methods would not create a waterfront that cuts off the tidal basin from the sea, he says, nor dam rivers to disrupt ship traffic. They involve the production and transportation of liquid hydrogen with special piping in conjunction with superconducting channels of transmission. His topics are marine hydro kinetic, rivers (channels) power plants without a dam, low-speed hydro-kinetic turbines, large power hydro turbines, examples of turbines produced, and water current power-looking to the future.
