Have not seen this mentioned. This link I posted makes some good points.
This project has been in the works for some time now.
I had told my wife that they should cover the canals with PVs years ago and I'm happy to see it actually take form. Too huge benefits
a) water evaporation limited and boy, we need to preserve water
b)Power about 10 million homes with this project.
In 2021, scientists published a feasibility study about erecting solar panels over canals, and it's about to become a reality.
