High voltage DC transmission is somewhat scary. It's really easy to create and sustain arcs at much lower voltage than AC, and there are risks from things like electromigration relating to the current always flowing in one direction. Nonetheless, it's a neat curiosity, sort of like the cable car of the electric utility world.
