A run-of-the-river or ocean current turbine may comprise a hatch 1612 and a slanted block 1605 having protector ribs 1630 for directing water flow to a waterwheel 1608, The hatch may be controlled by a plurality of Transgear™ gear assemblies 2210, 2220, 2230, 2240 for varying the amount of water flow to the waterwheel from extreme drought to flood conditions so that the waterwheel may turn at rated speeds and within a predetermined range. The Transgear gear assemblies may comprise an accumulator 3010 for accumulating a rough and a fine tuned waterwheel speed. The Transgear assemblies may comprise embodiments of power take-off switches for, for example, bi-directional or clockwise and counterclockwise waterwheel shaft rotation, The turbine may be aligned for top-feed, side-feed or bottom feed of water and may comprise a tail wing or first and second turbines facing in opposite directions to capture high and low tidal flow. |
