How NOCATCH works
A wave-powered green light that clips onto fishing nets.
1
Waves power it
A magnet slides through a coil every time the net moves. No battery.
Waves rock the deviceClipped to the net, it never stops moving
2
It blinks with the sea
Each wave charges it up, and the light flashes green.
Each wave makes a pulse of electricityfirst one way, then the other
3
Turtles see the net
They swim around it. Fish don't react, so the catch stays the same.
