Okay. Loads of money. How much money per joule produced?

That they will. How are you going to anchor your machine? Let's place one near Gibraltar. Tidal flow through there can get pretty wicked.

...and most of it has no currents generated by tides.
They do it all the time. U/W cement, piers, posts etc. Some types of tidal turbines are not anchored to the seabed at all. They are off the bottom of ship. It is not all about the strength of the currents, it is all about mass of the water moving. Large mass, low velocity needed. Smaller mass, higher velocity needed.
?????????????????????????????????????????????????????????????????????????????????????????????????????? Where the fuck are you getting this from?
More expensive offshore i'd imagine.
No doubt about that.
Dont know but it is being done now so it cant be too insane

Okay...show me a current in the open ocean caused by tides.

In other words, you don't know. You choose to ignore the cost, just like wind and solar.
The thread focuses on the so-called renewable energy generation options. Not what is the most cosr efficient.
That being the framework i just added reliability as a distinguishing feature.
If we are after economical then coal is the winner at least in this country.

No. It is about being to meet the Paris accords (which is not possible, since it's not possible to measure global atmospheric CO2 content anyway). Thus, it turns into discussion of economics of different energy sources.
Coal is extremely cheap. Both oil and natural gas are renewable energy sources, and also quite cheap. We don't yet know about coal, but there is a LOT of it. Nuclear is more expensive, but not anywhere nearly expensive as wind or solar. Tidal power stations are limited to very few suitable sites and are expensive as well. Hydroelectric is reasonably priced, but it too is limited only to relatively few suitable sites.
What is wrong with CO2? Describe 'greenhouse effect' without violating the 1st or 2nd laws of thermodynamics or the Stefan-Boltzmann law.
Are you really that uneducated on this subject? Do me a favor, learn at least a little about what you are talking about before talking to me about it. What the hell do you think causes currents? Fucking idiot.
My mistake re Paris. Didnt think we signed onto that foolishness so just didnt register.
I could not care less about co2 the worst it does is grow plants great.
Wind and solar are not reliable. Tides may be a bit higher or lower but they are coming every x hours no matter what.
No one said that. Learn how to read and comprehend.

Differences of temperature. Not tides. Not in the open ocean.

Approx 6 hours. What good is tide in the open ocean? The only place you could harness one is where tides cause currents through narrow passages. Sure, you could do that, but there aren't that many sites, and you still have to solidly anchor the machine (expensive). Then of course is the difficulty with maintenance in corrosive sea water, and the difficult of servicing such a machine (the tides don't stop for maintenance!).
That is one aspect of it. Thermohaline circulation. And wind. And of course, ebbing and flowing of worldwide tides. Like I said before, learn something before speaking to me about this.
