Offshore Rectennas
Could microwave receivers be built at sea, and what would that solve?
Chapter summary
possibly, and it would address the largest siting problem.
Key takeaways
- 1
A rectenna of 25–40 square kilometres near a coastal city competes with land for homes, farms and nature; at sea, a floating or fixed mesh could sit offshore like a wind farm, using the same grid connections and experience.

- 3
The challenges are structure cost, corrosion, storms and shipping lanes.
