Cheap, renewable, clean energy. There’s just one problem.

    I think investors should always put their cash to work, especially In 2024, we'll start to see more market diversification. I'm hoping to invest about $350k of my savings in stocks against next year. Hope to make millions in 2024

    Over time, we are discovering that all 'green' energy is false. None of it works…. except on paper and with huge taxpayer subsidies. Environmentalists then get rich off of it, and the rest of us are left with a degraded energy supply.

    Presumably it will just have to take as long as it takes (probably decades) for materials to evolve to the point that they can take a significant pasting at sea without disintegrating, before this type of tidal power harnessing is feasible.

    Is there no way to construct an artificial bay whose resonant frequency is equal to the tides? Or even some fraction, to limit the power and also the damage to the turbines?

    If you've never been, go there. Don't just do 2-3 days, plan on a week minimum, and consider a month. Tour the whole coastline staring at Grand Manan, ending at Cape Breton. And oh look, PEI is just off shore 😊

    Why don’t they mount the generators on a floating pontoon and belt drive them from a robust paddle wheel. Have a mesh to stop the ice or tow it out the way.

    Looks like they have been trying to maximize the power
    by ignoring the rocks. Maybe if they set up screens
    to divert the rocks, etc. they will have a dependable
    power source. There are other areas: France and Korea
    that have similar tidal properties.
    Thanks Tom. I was not expecting to go to the bathroom
    with you and a camera.

    If only Government would back the Bristol barrage. Could produce 14% of the power demand predictably for the next century. At a price tag of £20bn while also providing a new road link across the channel whats not to like

    15 meter tidal change? Yes but those are the "Spring Tides". Average change, at the "extreme" minus basin, is less than 10 meters. Still very big but you should use average changes, not the extremes. That is what you would really generate power on. If you really want to generate power look at the English channel, 4 plus meter tides over 150 MILES. Plus you get a road to the continent AND stop most flooding of Holland and German north sea regions (Copenhagen has a tide of INCHES (like about 2-3 between high and low) ) so the damaging tides in the north sea could be stopped as they are just the tidal bore flowing the the English Channel. Dam-stop the entire bore and TADA:- NO high tide that day.

    Not sure what the point of this video is, but the oldest tidal energy plant was built in France in 1966. That's 56 years of tidal energy production, no broken turbines, etc. So why would you ask: "Can it be done?"

    Might a "Salter's Duck" setup be feasible? or an MHD setup – no blades to harm anything, and no stopping fish from going where they want to? or is the tidal enegy so strong that nothig can reliably be anchored there?

    Use the surplus electricity of grids, as hydrogen streams. Easy money. Electricity is already on hand, and it can be repackaged at any site of convenience.

    Cash in on the regenerative grid concept.

    You need a heavy and large dirty water reservoir you can open and close with gates or locks. Inside it, you need a smaller clean water reservoir like a bladder that is piped to below-grade tanks on shore. The turbines can be located in the clean-water pipe.

    Fish? Rocks? Surely putting a metal grill around the turbine, despite reducing its efficiency a bit, would protect the turbine and give the fish a fighting chance. If any backward looking populations – no matter their origins – are backward enough to complain about free energy, they’d have to be ignorant enough to not be even aware of underwater turbines. If they are made aware, but they’re dishonest and only in it for any benefits they can scrounge by pretending some kind of cultural violation then they’re an embarrassment to all the less dishonest members of their population and should be put in the corner by their honest fellows and otherwise ignored.

    I mean I don’t think anyone of importance will see my comment but did anyone tried vertical plane type moving part to create friction and does not effect the fish or any wild life as well as has the ability to withstand extreme water pressures ?
