WAVE ROLLER 

WaveRoller wave farm in operation during high tide.

WaveRoller is a device that converts ocean waves to energy and electricity. The machine operates in near-shore areas (approximately 0.3-2 km from the shore) at depths of between 8 and 20 meters. Depending on tidal conditions it is mostly or fully submerged and anchored to the seabed. A single WaveRoller unit (one panel) is rated at between 500kW and 1000kW, with a capacity factor of 25-50% depending on wave conditions at the project site.

HOW IT WORKS

WaveRoller behaves in essentially the same way as the flat part of the wreck that Rauno observed. The back and forth movement of water driven by wave surge puts the composite panel into motion.

To maximize the energy that WaveRoller panel can absorb from the waves, the device is installed under water at depths of approximately 8 – 20 meters, where the wave surge is most powerful. The panel spans almost the entire depth of the water column from the sea bed without breaking the surface. This ensures that the panel does not protrude onto the seascape and prevents the creation of material inefficiencies that would put additional load on the structure.

Report and Budget

Report

The protoype was designed with the necessity about the process of the serigraph and is built and adapted in some principal stages arised modifications. In this parcial we were focus in mechanic and power part. Because the principal thing is increase the efficiency of the mechanism and with that we can apply the control part on the machine. 

We get the mesh with the logo of the FIE and was adjusted  it accoding with the prototype. 

We did the counter and the clock on PCB and was welded the different circuits. And we controlled the step motor and this can move the mechanism that contains the mesh.

Describing or defining things in terms of their shape.

The Arch of Triumph

 date: 18/03/15

This is part of principals monuments of French, this monument looks like a big tailgate.
Napoleon Bonaparte ordered its building.between 1806- 1836.  The arch of triumph is 50 metres high, it is 45 metres wide. Also the arch is shaped  like a box with some  semicircles. this is for columns, which contain four statues, these represent people looks like a warriors.
 The name of the statues are "The  Triumph", "The Resistence ", The Pace" and "The Marsellesa".
