Now here's one of those ideas that leaps out at you with its commercial potential. Climbing offers extreme exercise with a nuclear fun factor and teaches fundamental coordination skills but it can be dangerous and scary with the heights involved, and besides, a climbing wall requires a serious commitment to locate and build. The computer-controlled ClimbStation is like an intelligent vertical treadmill for climbers, so it provides real climbing without the need for a safety harness because you never got more than a metre off the ground. ClimbStation hydraulically tilts between +15 degrees and minus 39 degrees, the holds are interchangeable, and the most significant thing about the ClimbStation is that it can be transported with a normal car trailer, making it an ideal relocatable owner-operator or amusement attraction.
