My prediction is that reliability will be the achilles heel of these systems. Thermal expansion, weathering, dirt/debris, twisting/racking, g-forces, lack of lubrication and component wear will be continual problems. I would do some accelerated product testing (500-1000 cycles in an environmental/dust chamber on a shaker table) before releasing this to unsuspecting customers. They are pretty renderings but I see some blatant design mistakes.
All the best,
Hein
