Would this be able to be used as a fuelless space propulsion method?

Ion drives are just particle accelerators so why not?

Maybe light sail and beaming energy from the home planet?

Solar sails might be able to beat it.https://en.wikipedia.org/wiki/Solar_sail

What about a photon rocket? https://en.m.wikipedia.org/wiki/Photon_rocket

this is great! check out project Orion https://en.wikipedia.org/wiki/Project_Orion_(nuclear_propuls...

Could this be used to make some variant of an ion drive?

Laser propulsion could work. I'll need to learn more about the physics of it.

Can it be done with solar sails?

Useful for a high velocity laser-sail or say, an ice rocket?
