Where does it get its power from? Won't be solar panels...


And why not? Just scale up the number of solar panels to
the required level to get to 1 or 2 Tesla.


Don't need intense, if you can get big.

... which is not where you really want this
half-baked system. The particles this "magnetic
shield" is to protect you from, are not moving
at c. And Mars is still whipping around at a
good clip. The "wake" this system produces will
fall behind Mars, not *around* Mars. You'd need
to "drive" the object a little forward of the
stability point.


The solar winds aren't travelling at c, they're
only going between 300 - 750 km/s.

So the "shield" will have to be WAY forward. About 43 minutes forward:
