They are all _conceptual studies_, of course, because at present the
energy requirements are too burdensome for us (ie, even aside from
engineering challenges concerning nanomaterials or scaling up lasers,
building one or more space lasers with the required power, ability to
focus the beam at large distances, etc., would be impossibly expensive).
But for a civilization with a developed presence in its own system,
these requirements would be trivial.

Unfortunately nothing in the space environment is trivial.
Especially for manned missions.
