There is a lot of air between you and space, unlike the moon and space. True. But the magnetic field is not insignificant. We'd be fine. False. And the power grid isn't going to be taken down by just the magnetic field switching off, even CMEs are only a risk to the grid because of how they react with the magnetic field (and even then we could prevent that but for the politics). Where are you getting this stuff man? Plus we could fairly trivially make a replacement magnetic field. Hahaha. Yeah right! As if

Conclusion (for Mars): > We have shown that the currents required are between ~0.2-0.5 GAmps in one or many solenoid loops. Whilst the power requirement will depend upon the material used, it can be estimated to be between 0.1 and 100 GW which is between less than one but up to 50 typical 2 GW power stations. While not trivial this is not unimaginably large, Even the big number is about half the annual installation of PV on Earth.

  Thank you! Interesting. Do you watch Suspicious Observers? What do you think? They cover many studies talking of the interactions of solar radiation, the galactic current sheet, and Earth phenomena.
