This is really key, there just isn't that much energy available in a small enough area for utility scale production. I would add the caveat that for small scale production, some schemes could actually work quite well, like some kite schemes. But no one is investing in small scale, all the development is for multi megawatt systems.
- jacquesm 5y agoThe linked article is a perfect example. Created to fit one specific location where it just might work and produce a pittance of energy twice every day. I'm curious if it will survive the first real test: a good storm. Never mind the power that it generates. But for sure a lot of money got blown on this.
- kylegordon 5y agoStorms create issues at depth? Even 45m under the sea?
- jacquesm 5y agoYes. Single waves can be 10 meters or more, the resulting currents and direction changes can easily affect the ocean up to 100 meters down from the surface. Really, marine engineering is an art, and anything that isn't solidly anchored is going to be the oceans plaything sooner or later.
