This is a seriously weird one. Of course it has been widely discussed.

The claims made are not documented and not consistent with reality. The shield may work and may even be doable. But nobody understands how it would lead to a thicker atmosphere in any way and the proposal does not give any pointer beside the claim itself. I say it is bogus or at least totally misleading.

There is one thing this shield could do. It could make terraforming of Mars by other means more durable. Without a magnetic shield any terraforming effort would be blown away in as short as maybe 100 million years.
