I'm not good at nautics, but in my understanding currents slowly stop and later turn around. Most tide charts are more or less a sine wave, with different highs and lows.
So it's interesting how this 100kw was produced.
The article only says: "The business was able to generate roughly 100 kilowatts of steady electricity during demonstrations earlier this year."
So is this over a few days or just a few hours while peak flow? While currents change, their change is highly forseeable - unlike wind.
- bayesian_horse 4y agoThe pods with the turbines are floating in the water, tethered to the seafloor, so they will turn in any direction the current is going.
- sandpaper26 4y agoCurrents are relatively unrelated to tides, and are fairly consistent over time (with some seasonal variation due to differences in hemispheric temperatures). From [1], "the large scale prevailing winds drive major persistent ocean currents..." Keyword is persistent.

- stjohnswarts 4y agoI imagine that's one goal of the project? I can't imagine that there hasn't been a shit ton of experiments with "deep" sea currents before this power experiment. I mean it's dead obvious and they wouldn't have ponied up the cash for this if ocean currents were all over the place.
