The device, a non-functioning prototype version that was shown off in the expo hall of Austin’s SXSW festival this week, uses a circular series of rotors to provide enough downward thrust to let the human wearer jump higher and for longer than is normally physically possible. The team behind the product says it should allow someone to jump two to three times higher than normal. The overall effect seems designed to replicate low-gravity environments, hence the moon-themed named.
