This is going to sound really stupid I am sure... again I'm not physics major or anything along that nature so forgive my ignorance... Are there other currents that are immediately dangerous to be around?

Let's say laser gun or something like that. I see a lot of movies with laser guns and it got me thinking how effective the laser would be in poor weather.

Could a laser be effective through ash or sand? Could a powerful enough laser burn through sand or ash and work effectively?

Would lightning work in space? I think it would but you wouldn't be able to see it? Let's say I have some sort of device that creates a lightning bolt, if I shot it at a watermelon in a vacuum or another target would it hit the target, or nothing happen because of the vacuum?
