Add on inspired by last evolution of the theme "Ceres".
=============================================

Deffinitely a http://en.wikipedia.org/wiki/Plasma_window is http://en.wikipedia.org/wiki/Plasmoid.

Plasmoids are the Bolonkin`s plasma cords for wireless transmission of electricity in vacuum -- http://www.google.co.uk/search?hl=en&q= … kin+&meta= -- , too.

A cage of plasma cords IS a "plasma shield mesh".

Re: Hints for atmospheric retention...

Has anyone seen any discussion of whether Bolonkin's plasma cords would actually stay stable?

Re: Hints for atmospheric retention...

hmmm

I've heard that the Earth's magnetic field is actually rather weak..

It can take that much to generate an artificial one, strong enough to protect the colonists/atmosphere on Mars - can it?

I don't have a lot of technical info about this - can anybody inform me?

Re: Hints for atmospheric retention...

If we got Mars' air pressure up to 1 Bar it would last many millions of years.  Also the greater air depth would provide plenty of radiation protection just as the Earth's atmosphere protects the Eskimos from all the solar particles that would hit the Earth. 

If you check the FAQ, there are links about Mars' magnetic field there.

Warm regards, Rick.

Re: Hints for atmospheric retention...

It's been recently calculated by Ong & Asphaug that for 1 km asteroid impactors travelling at 45 km/s (something that happens every couple million years or so) a Martian atmosphere of 150 mbar would be thick enough to completely quelch atmospheric impact erosion.

At 150 mbar the Martian surface would enjoy x-ray and cosmic ray protection comparable to that at Everest base camp (quite tolerable). As long as at least 1 mbar of  this is O2 you can form an ozone layer about as thick as Earth's.
