Bubble curtain
One section of the bubble ring through a tide, in cross-section (true scale, 7 m design depth; time sped up). Four air pipes 2.5 m apart and one float line with a 1.5 m skirt, 1.9 m past the plant-side pipe, toward the intake; the sea side is open. Jellyfish drift in over the open sea side and are held circulating between the last plume and the skirt. A robot noses in over the curtain, bow first, so its 1.6 m mouth sits in the held band about 1 m down, and lifts them out. Where water flows out of the ring the air is off and held animals drift back out to sea; where the tide pushes in hard the air is boosted to 0.6 Nm³/min per metre of pipe, inside the same power cap.
Simulation
SIMULATION · MODEL OUTPUTThe same 3-day bloom and the same tide, run twice in our model: left without protection, right with the bubble ring and 12 robots. This is tide start 21 of 24, the run closest to the 24-run average. Average of all 24 runs (central case): 73 down to 18 tonnes a day reaching the intake, 75% less. Model output, not a measurement.
Relocation robots
ANIMATED ON OUR CAD CONCEPT MODELLift, carry, release. A slow screw (21 rpm) lifts the jellyfish in pockets of water, and a sloped chute takes them into the flooded well with no free fall. The fleet map shows 12 robots, about 10 at sea, at a typical moment under our fleet model's rules: collecting bow-in where the held band is thickest, carrying about 1.9 t each 8 km offshore (55 min each way), releasing, heading back, and charging at the docks on the breakwater arms. Designed for live handling; survival rates are measured in the Phase 0 trials.
A 12-second turntable of our CAD concept model: a 12 m catamaran with a slow screw lift at the bow. Main dimensions come from our sizing models; the rest are our assumptions.
