The Wilton Water Wheel which is the heart of the Tidal Cube, has two sides, each side has spokes, the
spokes are connected side to side by pivot rods and each rod has a "blade". The pivoting blades provide either
the least resistance or the maximum resistance against the horizontal laminar flow. The net of these resistances, is an efficient,
completely submerged, aquadynamic power plant.
Each
blade has four functions:
1) Flying,
2) Pushed Back,
3)
Locked, and
4) Released.
For the purpose of defining terms and illustration let's say that an outgoing tide comes from the right and flows to the left.
So, in an outgoing tide, the top blades become 1) Flying and provides the least amount of resistance against the tidal flow.
(Imagine a set of Venitian Blinds letting light into the room). The blades facing the flow are: 2) Pushed Back, cumulatively
all the blades overlap against each other causing what we call a solid wall. The "Solid Wall" rotates to the bottom
of the wheel and takes the full perpendicular, blunt force of the outgoing tide, the maximum amount of resistance, and turns
the wheel clockwise. After the wheel has been forced to rotate an additional 45 to 90 degrees the blades go into the 4) Released
position where it comes back around once more to the 1) Flying position where it started. The totals of the resistances cause
the wheel to turn clockwise continually.
After the outgoing tide is complete, the incomming tide begins. The tidal flow is now from left to right. In
this case, all of the above mentioned blade functions are reversed.
Now the top blades are locked, achieving the maximum amount of resistance, and the bottom blades are flying, causing
the least amount of resistance, and the wheel rotates once again, in the same clockwise direction.
Consequently, whether it's an incomming or outgoing tidal flow, the Tidal Cube produces
force in a single rotational direction.
The carbon fiber assembly rests on two end axle points. Each end has a water resistant HDPE bearing system for thrust
and load. The two point bearing system increases the strength of the forces that can be handled unlike the
standard propeller single axle systems in trials today. The bearings rest in a HDPE (High Density Poly Ethyelene) mounting
wall that is secured to the tidal floor with standard pier pylons. The near sided bearing has a 13:1+/- gear increaser that
runs a centrifigal pump system that pumps "clean" water in a closed loop system to a shore pump that turns
a generator. 
The Cube contains the wheel, gear increaser, bearings, and the valved pump system. The pump forces water in a closed
loop system through flexible high strength hoses to the shore pump which spins the generator. 
Installation services are available or the kits can be installed by customers and you'll be off the grid in no time at all.
