Interesting Engineering: Hybrid energy raft could power 1,000 homes a day with wave, wind, solar (interestingengineering.com)

NoviOcean’s wave power technology, developed over several years, has been tested in wave pools and a real environment near Stockholm. A small version powers homes on Svanholmen island, proving the concept works at sea.

On one square kilometer, 15 wave power plants can generate 15 MW, compared to offshore wind’s 10 MW. Combined, they can produce 25 MW, sharing the costs of the sea area and transmission cable.

According to the firm, the hybrid approach delivers more consistent energy, as waves generate power for days after the wind subsides. Additionally, wave plants can be placed closer to shore without visually disturbing the coastline.

For fuck's sake, a microreactor could do all of this for the footprint of a bedroom (plus some additional space for the staff). It would work for years and constantly provide power with no issues from storms, dust, salt, or needing distributed maintenance (and environmental disruption) over a square km.

This isn's just some generic hand waving. Go look up the company Radiant. It's going to happen within a few years. Demonstration is slated for 2026.

So what are you saying, that we should give up on other technologies? Two years before your microreactor is demonstrated?

This is a fanciful and complex power system that is proposed that cannot produce consistent power reliably. I don't think it will be viable in the long run.

Well, I'm sold. We should definitely turn everything off and wait for the hypothetical reactor to materialise.

That's not what I said, and your comment is disingenuous in that regard.

How is it fanciful? It's taking a bunch of solid, proven technologies and putting them in the same place. It's nothing more than a standard engineering project.

I’m not yet convinced this technology is the future or anything, but it does look pretty promising. We’ll know better when DOME testing begins in 2026.
