SECTION OF MOVING BREAKWATER WAVE GENERATOR HYDRAULIC FLUID

HYDRAULIC FLUID TANK Hydraulic fluid returns to a tank where it is stored until the next wave

WAVE ENERGY GENERATOR The moving breakwater modules move up and down with the incoming waves. Thyborøn is an area with waves of high frequency and height making it an ideal place to collect wave energy year round.

TIDAL CHANNELS ON SITE There are three tidal channels with generators on site.

TIDAL CHANNEL Tidal flow is concentrated into narrow troughs to increase flow

PIEZOELECTRIC TRELLIS WIND GENERATOR

OPEN CENTER TIDAL GENERATOR Open center tidal generators have an open center to allow marine life through. They are also very quiet.

FLEXIBLE SHAFT

WHAT IS PIEZOELECTRIC POWER GENERATION? Piezoelectric means literally ‘pressing electricity’. The technology is not new and essentially intales the compression and expansion of crystals to generate current. Arrays of these crystal panels can be used to create energy. Large scale energy harvesting is not yet commercially available but by project completion it is expected to be ready.

HEAT EXCHANGE

TRELLIS RADIANT HEAT SYSTEM The energy generated by the trellis piezoelectric generators run the pumps for the trellis radiant heat system which is connected to a heat exchange linked to heat producing elements such as the bio digesters, bakery, and brewery.

TRELLIS IRRIGATION & LIGHTING The energy generated by the trellis piezoelectric generators run the pumps for the intigrated irrigation and lighting system.

CONCLUSION The three energy sources drive the building and masterplan form. Wave energy is harnessed by the scallop shaped moving breakwater generator, tidal energy is focused through narrow channels, and wind energy vibrates the trellis. 51
