ja7tdo Posted March 30, 2019 Share Posted March 30, 2019 hi, There is a potential difference of 300,000 volts between the surface and the 30 km ionosphere above. The atmosphere is ionized by cosmic rays.There is a potential difference of 100 V per meter near the ground surface, but the potential difference gradually decreases as it goes up, and it becomes 0 V at 30 km. Atmospheric pressure is generated because the ionized atmosphere is drawn against the surface minus.

swansont Posted March 30, 2019 Share Posted March 30, 2019 Now show data that back this up. And explain why there is pressure above 30 km, and how planes can fly above this altitude. Link to comment Share on other sites More sharing options...

The earth is blowing the wind of plasma from the sun, giving a voltage of 300,000 volts to the ionosphere. It is observed that there is a potential difference in the atmosphere ionized by cosmic rays. It has been proven that elastic fluid does not transmit pressure in the open system. In atmospheric pressure, pressure is generated by ion wind. Do you forbid URL link even though this is the Internet? It's classical. Link to comment Share on other sites More sharing options...
MigL Posted April 3, 2019 Share Posted April 3, 2019 So an SR-71 is flying at 80000 ft ( about 20 km, ) and is at equilibrium with the potential at that height. What keeps the plane up ??? Should it not be attracted to the ground ??? You say there is no air pressure in an open system, so there is no pressure differential to provide lift. Why are no planes falling out of the sky ??? Maybe look out the window sometime, and observe reality. You may find it doesn't agree with your humorous notions. Link to comment Share on other sites More sharing options...

If there is no potential difference at 30 km, as you claim, how is there a pressure above that point, if the pressure is (somehow) due to this PD? 9 hours ago, ja7tdo said: Do you forbid URL link even though this is the Internet? It's classical. For newcomers, yes. It cuts down on spam, which is also "classical" Link to comment Share on other sites More sharing options...
