Hanyoung Lee wants you to be seen. The South Korea-based product designer devised a prototypical warning device to prevent pedestrian strikes along roadway crosswalks. It's called the Virtual Wall, a visual barrier created from plasma laser beams.

“I don’t know of another place in the universe that would have this intensity of light.” That’s a quote from physicist Karl Krushelnick of the University of Michigan. It might sound a bit bold, but he and his team believe they’ve developed a laser beam with record-smashing intensity. According to the scientists, the HERCULES laser is so powerful that it’s roughly equivalent to concentrating all the sunlight heading towards Earth on a single grain of sand.

Sounds too futuristic to be true? See below for a video of the Skyguard system taking out mortar rounds, artillery shells and rockets
