Aqua Duct (Automatic Builder)
To increase grass land and protect from soil erosion a system to distribute water at an affordable cost is a good idea. The following design concept is an algae growth system to yield plastics then via roving printer riding on a guide ...with the ability to "print" plastic derived from the algae grown upon the wheels in algae growth coils...
The base segments can also be installed by similar design system with robotic servo arms then installing the base guide rails. the sections will reach a given height then as an independent unit that contains the similar processes ride atop the rising wall until the flow elevation and declination is then attained.... Fuel less pumping will assist in water flow where required. Don't forget the Arches... between countries... :)
