The idea behind Hanyoung Lee’s Virtual Wall concept is that plasma laser beams would assist pedestrians while they cross from one side to another, so they don’t have to worry about being run over. The light-formed force-field type barrier would keep cars and humans apart.
Many questions remain, like what happens if your car runs into it? Will you get a flat? Will it kill your engine like a UFO? Despite our lingering questions, we can’t wait for something like this to become reality. Mostly because we like shiny red plasma laser beams.
