What does this have to do with Global Warming you ask. That's easy of course. The answer is Science Friction. As the earth revolves under the water it creates friction.
Is there anyone beyond third grade that doesn't understand how tides work?
What a pretentious twat. Does he suppose that people fail to realize that the water level rises and falls, and that they instead assume that the hand of God draws the water in and out twice a day on His whim?
Given what is taught in schools is completely different than this, yes, there are a lot of people who don't understand the tides and I have seen and heard so many explanations that it has ceased to be relevant anymore. I'm not sure what number this explanation is in the line but I expect another to come along in a few years.
If the Earth didn't rotate around the sun and the Moon didn't rotate around the Earth, that might be interesting. Tyson probably believes what he's saying. It's a wonder he doesn't think the Earth is flat.
i had always heard that the moon was the reason for the tides, but based on what i know about gravitational theory, this explanation of the tides makes *some* sense to me. Yes, the Earth is *orbiting* the sun (while rotating on its axis) and the changes in relative positions * might * be an explanation of tide variations? (tides that are unusually high or low?) Is there a better explanation of tides out there somewhere? (err...i found my answer by searching youtube...)
Electricity from tidal changes is done on a small scale in Annapolis Royal. It's where the Annapolis River drains into the Annapolis Basin. Since the late 1970s. Not 50 foot though. You have to go way up the Bay of Fundy for those. Minas Basin.
Tidal power generation is a maintenance nightmare. Sea life deciding to live in the generators, etc. The juice ain't worth the squeeze, if you'll pardon the pun.
A geophysicist once explained to me that tides are strongly affected by resonance. When you walk with a cup of coffee, at least one of the vibrations your body generates is close to one of the natural frequencies of the body of coffee in the cup, so that the coffee begins to slosh back and forth and will slosh out if you don't stop for a moment. The ocean water corresponds to the coffee, of course; a straight coastline, or bay, with the geometry of the adjacent ocean bottom, corresponds to the coffee cup; and the gravities of the sun and moon are the exciting forces. This explains why tidal differences vary so much from place to place. In Seattle, the tidal difference is several feet. In the Japan Sea, the tidal difference is about 1 foot. In the Bay of Fundy, it's about 60 feet. Watching the tide come in at the Bay of Fundy is one of the things on my bucket list.

ReplyDeleteAnnnnnnns, Friction generates HEAT, which is why our climate is warming up. I mean, ain't that BELIEVABLE?????? Suuuuuuuuuuuuuuuuuuuuuuuuuure it is...
DeleteThank the leftists for the dumbing down of the populace.....

Pay no attention to him. He is a mid-wit with a good speaking voice, an empty suit.

DeleteWhat ever happened to the proposal of utilizing the 50 foot tide differential in the Bay of Fundy to generate electricity?

DeleteNot quite 100% true.

Right. The sun and moon aren't on opposite sides all the time (or even most of the time), for one thing.
DeleteThings like this are what I don't like about Neil DeGrasse Tyson.
There is proof right there of “white supremacy”.

50 feet not 60, as Anonymous noted above.
