Mobile Tactical High Energy Laser

This clip of the MTHEL (Mobile Tactical High Energy Laser) shows it shooting “3 simultaneous mortar rounds in-flight, right out of the sky.”

MTHEL uses directed energy (laser beam) to intercept aerial targets such as rockets, missiles, artillery shells and other aerial threats. The target destruction is achieved by projecting a highly focused, high-power laser beam, delivered by a chemical laser, with enough energy to affect the target, and explode it in midair

Laser Harp

The “Laser Harp” by Jen Lewin is an immersive installation that uses “movement and laser light to trigger sound.”

The use of light instead of a physical string plays with our perception of space and matter. What is physically not there (the virtual string), responds as if it were
