There are several types of open-flow devices that can be used in marine-current-power applications; many of them are modern descendants of the water wheel or similar. However, the more technically sophisticated designs, derived from wind-power rotors, are the most likely to achieve enough cost-effectiveness and reliability to be practical in a massive marine-current-power future scenario.
