Apparently one Platinum DieHard battery can power a cube of lights, a double-stacked keyboard, 24 cars without batteries, and um, Gary Numan. Watch the ’79 one-hit wonder perform “Cars” on keyboards hooked up to car horns. He’s aged, hasn’t he?
Over three days in the desert, a team of six engineers worked on 24 cars and removed the batteries from each. Instead, they connected them all together to a central computer and a keyboard. The horns inside the cars were removed and instead an MP3 player was used to tune it. The entire set-up was hooked to one DieHard battery. .. As Numan hit each key on his keyboard, the software turned on the lights and sound for the corresponding car.
