Solar winds can photo-dissociate the carbon dioxide atmosphere of Venus into carbon monoxide and atomic-oxygen, in the long lived monadic single state. This monadic oxygen can recombine with solar hydrogen to form water vapour.
The thinly induced magnetosphere of Venus is incapable of preventing the loss of this carbon dioxide, carbon monoxide and water vapour, which is continuously blown away though a solar induced magneto-tail, that is focused like a gravitational lens to reach earth orbit.
In effect the upper-atmosphere of Venus is positively charged, the upper-atmosphere of Earth is negatively charged, and there can be an electrical connection between these two opposite charges depending on the pressure (?) of the solar wind.
This situation seems charged with speculative potential.

VENUS' TAIL REACHES ALL THE WAY TO EARTH. Recently the Venus shadow, cast by the Sun, passed across the SOHO satellite (in Earth orbit), allowing SOHO to detect the plume of ions kicked out of Venus' upper atmosphere by the solar wind. (Geophysical Research Letters, Vol 24, p. 1163; New Scientist, 31 May.)
The "induced magnetotail" that points away from Venus in the direction of the earth is a teardrop-shaped plasma structure filled with “a lot of little stringy things” that was first detected by NASA’s Pioneer Venus Orbiter in the late 1970s. In 1997, Europe’s Solar and Heliospheric Observatory (SOHO) Satellite showed that the tail stretched some 45,000,000 kilometres into space, more than 600 times as far as anyone had realized and almost far enough to “tickle” the earth when the two planets are in line with the sun.
“In this sense”, scientists write, “Venus can be likened to a comet, which has an induced magnetotail of similar origin.”
Venus has an ion-packed tail 45 million km/28 million mi in length that stretches away from the Sun and is caused by the bombardment of the ions in Venus's upper atmosphere by the solar wind. It was first discovered in the late 1970s but it was not until 1997 that the Solar Heliospheric Observatory revealed its immense length.
ONE of our neighbouring planets can still pack a few surprises, it seems. Using satellite data, an international team of researchers has found that Venus sports a giant, ion-packed tail that stretches almost far enough to tickle the Earth when the two planets are in line with the Sun.
"I didn't expect to find it," says team member Marcia Neugebauer of the Jet Propulsion Laboratory in Pasadena, California. "It's a really strong signal, and there's no doubt it's real."
NASA's Pioneer Venus Orbiter first found the tail in the late 1970s. Around 70 000 kilometres from the planet, the spacecraft detected bursts of hot, energetic ions, or plasma. The tail exists because ions in Venus's upper atmosphere are bombarded by the solar wind, a stream of plasma that blows out from the Sun.
The Venus tail does respond to solar activity and contains significantly less magnetic flux at solar minimum.
The plasma sheath of Venus is extremely long, almost touching the Earth when the two planets are at their closest approach. Jupiter's plasma sheath has the same relationship with Saturn. Recently NASA astronomers have discovered what they call 'stringy things' in the long plasma tail of Venus. Such twisted (stringy) filaments are exactly the paths Birkeland currents take in plasmas. Apparently Venus is discharging an electrical current.
