The Kelpedo™

Seaweed.
A New Approach.
More than just a structure for growing seaweed, the Kelpedo™ is our sustainable ocean health system. Each unit actively restores the marine environment by sequestering carbon, cleaning the water, and creating a vital, complex habitat for marine life. It’s a tangible solution for a healthier ocean, built on practical innovation and a deep respect for the sea.
