Discussion Overview

The discussion revolves around the concept of modifying hurricanes and preventing tornadoes through the use of a pipeline that utilizes the Earth's rotational velocity. Participants explore the feasibility of using cold water from the Arctic to influence weather patterns in the Gulf of Mexico, with a focus on the physics of pressure differences and gravitational effects at different latitudes.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation
  • Mathematical reasoning

Main Points Raised

  • One participant proposes that a pipeline could be constructed to pump cold water from the Arctic to the Gulf of Mexico to weaken hurricanes and prevent tornadoes, leveraging the Earth's rotation as a pump.
  • Another participant argues that the centrifugal force causes the oceans and continents to pile up at the equator, suggesting that this would prevent the proposed system from functioning as intended.
  • Some participants discuss the implications of gravitational differences at the poles and equator, noting that a 200 lb man would weigh slightly less at the equator due to these differences.
  • Concerns are raised about the practicality of maintaining the same elevation for both ends of the pipeline, with one participant questioning whether the pipeline would need to start significantly above sea level.
  • Several participants challenge the idea of a 13-mile difference in elevation between the poles and equator, citing the Earth's shape and the effects of rotation on water distribution.
  • One participant humorously suggests that if pressure differences drive flow, then one could theoretically run a pipe to space to siphon water out of the ocean, highlighting the absurdity of the original proposal.
  • Another participant emphasizes that pressure at sea level is uniform and that any perturbation would return to equilibrium, questioning the feasibility of the proposed system.
  • Multiple participants express frustration with repetitive arguments and emphasize the need for understanding counter-arguments presented in the discussion.

Areas of Agreement / Disagreement

The discussion contains multiple competing views, with no consensus reached on the feasibility of the proposed pipeline system or the underlying physics. Participants express differing opinions on gravitational effects, pressure differences, and the practicality of the idea.

Contextual Notes

Participants reference various physical principles, including gravitational force, pressure differences, and the Earth's shape, but these concepts remain contested and are not resolved within the discussion.

I figured out how to modify (weaken) a Hurricane and prevent tornados with
a pipeline while using the rotational velocity of the Earth. Actually, the
Earth is a Giant Pump.Gravity is greater at the poles of the Earth because
the Earth is not spinning with as much velocity. This why you would weigh
more at the poles. At the Equator the Earth is rotating at near >1000kmphr.
If you were to run a pipeline with both openings at the same elevation at
each location water would flow from the pole to the equator.If we can build
a pipeline from the artic ocean to the Fl keys it would be possible to pump
very cold water using the Earth as a pump. No electricity needed. Open a
valve near the end and cold water would flow and mix into the gulfstream
near keys thus weakening hurricanes and perhaps preventing tornados if cool
water is sent to the Gulf Of Mexico,also.

Can you Calculate the exit velocity of the water from the pipeline at the Equater and don't forget the angular velocity?

"Earth The Giant Pump"

PS Think of the electricity it can make?

Because of the centrifugal force, the oceans and continents already pile up at the equator, making the Earth a flattened (oblate) sphereoid. So this wouldn't work.

Welcome aboard, though!

edit: The difference between the polar and equatorial radius of the Earth is about 13 miles, so if the Earth were a perfect sphere (and you could somehow keep the oceans in place), such a device would work like a 13 mile-high hydroelectric dam.

If the elevation is the same then the shape of the Earth should not matter.Also, a 200 LB man at the poles would weigh 199.5 lbs at the Equator.This means there is more force at the poles and there would be a difference in pressure between the two pipe ends.Difference in pressure= flow.

If the elevation is the same at the polar end as at the equitorial end, then the pipe would have to start 13 miles above the artic ocean, wouldn't it?
 
I know the ocean has about a six inch bulge at the equator but I dought a 13 mile difference between the pole and equator. Circumference maybe but not radius.It would be 13 miles higher if the Earth was not rotating but it is.

1. Circumference at equator = 40 074 km

2. Circumference at poles = 40 007 km

3. Diameter at equator = 12 756 km

4. Diameter at poles = 12 714 km

The Earth is a large squishy ball, so the effect you speak of does no longer exist. Earth equilibrates itself. Think of it this way: There already is a water pathway between the poles and the equator. Do you imagine that wrapping some of that water in a pipe is going to magically make it flow? Reminds me of the old joke about the "outer space vacuum pump": since there is good vacuum in space, all we need to do is run a copper pipe from there to here and we can suck all the vacuum we want :wink:

At the same elevation! But the Earth has been allowed to run as a 'pump' for billions of years, and there is no longer such a same elevation. Pressure at sea level everywhere is the same. Perturb it, and it will return to equilibrium.
 
Not exactly, otherwise a 200lb man would weigh 199.5 lbs at the pole.

errorist,

You seem to be repeating the same things over and over again, apparently because you are not reading the responses you have already been given. As hard as it may be to accept, your idea is flawed, and no such "pump" would work. Please take the time to understand the counter-arguments presented before simply repeating yourself.

I am but a difference in force equals a difference in pressure. A difference in pressure = flow. It is well documented.

Methinks you are misquoting something, here.

Suppose you are right.

Consider a hill, with a river running up it. No really, running up that hill. Gravity, as we know, is weaker at higher altitude. So yes, there is low pressure up high. Funny how we don't see many uphill-flowing rivers.

Net Force --- don't just look at gravitational force. You are fighting isostasy with an incomplete analysis.

Wait, guys, I think errorist may be on to something:

Pressure difference is indeed what drives water flow. But why stop there? A man in geostationary orbit, 22,000 miles above the Indian Ocean is weightless - so why not send a pipe up to him and have the pressure difference siphon water out of the Indian Ocean (driving a turbine, of course) and out into space?

Well, maybe that's too expensive - how 'bout this: The Colorado river (before the dams) runs from the Rockes in Utah to Baja California. Since the rockies are higher above sea level, that 200lb man would weigh less in the Rockies than in Baja. So why not just run a pipe along the river from Baja to the Rockies in Utah and let the water flow (through a turbine, of course) up to Salt Lake?

Or am I doing something wrong...? errorist?
 
  • #15
The reason he weighs less at the equator is because of the rotational velocity of the Earth.

errorist,

Your "paradox" has been explained several times now, yet you continue to repeat the same things. You've been given the answer. I'm locking this thread.
