Do you remember those little plastic number puzzles? I loved those things. Well, innovation strikes again. When trying to solve a parking space problem, the idea of going vertical is nothing new. But what happens when you don’t want the massive time and cost involved in building a parking garage? Believe it or not, a portable vertical parking structure has been created and it’s based on the number puzzle system. Each slot has a numeric ID and can be shifted into any other location. The attendant simply enters the slot ID that is needed at ground level and the number puzzle algorithm takes over. It takes up to 3 minutes for a car at the top level to be available on the bottom level, so call ahead. The old systems of this nature typically require the cars from the lower levels to be removed while the higher platforms are lowered. Not so here. The cars are shuffled. No worries about the valet or attendant marking the outside of your car, taking your change or leaving strange odors behind.
