Modern windmills produce about 10MW EACH! While being cheaper, simpler, easier to maintain etc. Wave power is simply not feasible.

Main issue is that it is a direct competitor to wind power(no wind = no waves), and windmills are simply simpler/cheaper/better.

North American homes consume about 1MWh per month. So 2-3 Kwh per day, so 6 MW, about 2000 to 3000 homes.

Depends how long you can maintain it. For 1 sec? Not much. 24/7/365? Significantly more. MWh is a more useful metric than MW (w/o context).

Solar panels don't produce when the sun doesn't shine or at night. Same with wind turbines and...well, wind. Can't assume 100% uptime.

Sure you can. You can say the plant produces X MWh/day on average, which you could use to roughly calculate the production uptime.

It says each power station produces 6 megawatts, not each float. That is probably peak performance during rough seas.

That's awful, and I'm still sceptical. They tested it and STILL think it's useful? Seems like one of those ideas you have in high school.

Yeah I'm kind of thrown off by that. They don't say how big the plant needs to be to make that much. Or the price.

6 years ago | Likes 1 Dislikes 0

It says a complete station has 20 floats, so each float produces 300 kW. No mention of price, or maintenance costs. Probably unfeasible.

And not too rough seas, then it shuts down. Just like windmills, it's only usable when the wind is within specs.
