Re: Generating Power 24/7 by using Tides

Your conclusion is based on existing knowledge you have. But let me tell you how Air, Liquid and Solids work differently. Throw 100 ton Solid block on electric Pole. It will act exactly according to your theory and you are right. If the pole can't withstand against the force exerted by that solid ob...

I think something like this (Energy to go: the world’s smallest hydropower plant | Eco-at-Africa) is more interesting to me: https://www.youtube.com/watch?v=iNuZaaJZd3w
This is good for micro scale generation but needs always flowing water. Very Good for people who live near it.

Re: Generating Power 24/7 by using Tides

If what you claim is true, then you could divide ANY wall, dam, berm or levee into tiny sections and it would become much, much stronger and easier to build to withstand the same force. Thirty seconds of experimentation proves this false. The video claims it and that's what is mentioned in the vide...

Re: Generating Power 24/7 by using Tides

"If you have a wall X meters long, and it will have to withstand Y height of water, the amount of force each section of wall has to withstand is exactly the same when summed over the entire wall." ONLY If it is continuous wall, without sections. When the wall is divided into sections, this...

They mention it as portable and costs less than existing methods. Imagine the transportation cost of transferring the gravel to build the lagoon vs using pre fabricated piles, which are 100 times smaller in volume and weight. Pile walls can work. They are still effective around the Santa Monica Pier...

Re: Generating Power 24/7 by using Tides

Well, here is another experiment. Place a pressure measuring device in a tank on side wall at the bottom. Measure the pressure or force at that point. Pressure is constant all across the wall in that horizontal line. Let's say pressure you measure was 1000 pascal. So lets say the wall is 100 unit lo...

Re: Generating Power 24/7 by using Tides

Thames wall / implementation proves the same thing mentioned in the video. Check the actual thickness of the moving barrier at the bottom, it is very very thin, that means you can have thin member all the way up and it will still hold the water e.g. think of vertical column or panel or sluice gate c...

No, I'm not Civil engineer, but I know Engineers are those people, who can accurately learn and repeat the things invented by non-engineers.

Re: Generating Power 24/7 by using Tides

That design don't need that thick wall. That's the principle of design. Divide and Conquer kind of philosophy. If it is continuous wall, then your statement is valid. If you partition wall, the forces are not propagated along its length, that's the point of that design. You see a unit area of water ...

Re: World's most efficient and aerodynamic car

Simulations may well show more efficiency, depending on what the simulator is ignoring. (All simulators use shortcuts to speed execution time; one method is to not calculate certain parasitics if they are not deemed to be important.) Is there a way we can simulate it easily? Or you have the ability...

That's what the company is claiming. Does that mean they are better than Tesla, BYD, Faraday Future, Lucid Motors, Byton, BMW, Fisker, Mercedes, Nissan, Toyota and all other companies?

For those who were wondering about Rotomax 150cc inductance, etc. http://i.imgur.com/i8IsP5A.jpg Received my rotomax 150cc today. Wires are a lot thinner than my old CA120, almost like 4-6mm².
