Re: Magnetic Bubble/Protect Astronauts

Only trouble with a magnetic field bubble will be the power source needed, Most likely nuclear. Have not read article as of yet but will thanks for posting it cindy.

Re: Magnetic Bubble/Protect Astronauts

A magnetic sail was once considered to be a replacement for real solar sails. This was to use plasma generated to be pushed by the suns light. If anyone has a generator for power strong enough to make a bubble strong enough then it would come from this research.

The Earths bubble is strong enough. But the Earth is to heavy.

Re: Magnetic Bubble/Protect Astronauts

A magnetic sail would be pushed by the solar wind, rather than by light.

Re: Magnetic Bubble/Protect Astronauts

The field that is generated in this style design will not be robust enough to slow the particles down on impact with the magnetic field. This is impart due to field strength intensity. But if an outer jacket with an ozone layer inside of the chamber shells were created then the particles would be obsorb as if in a plasma area with the magnetic field. Also line the next layer shell with a water jacket to further slow down other particle types would also add to the amount of protection.
