another alternative to building stations.

unfortuately, even if you catch the entire energy from their momentum,
it would still be much lighter than that from light, and the equipment
to generate those fields are much heavier that those needed for the
light sails. I check these out too. the rotation of both the meterorid
and asteriod would have to be stopped inorder to be moved. in the
case of meteriods, the light sail would be between it and the sun,
which would stop it from losing material to the solar wind and heat.
