I found this challenge very exciting.
I proposed eliminating the mechanical chain and gearing system with electronics.
In most air-cooled heat exchangers, the construction utilizes a tube, through which the fluid passes, and fins over which the air passes to remove the heat. Some present units use an aluminum tube and an aluminum fin which are bonded together through a high temperature brazing process.
An effective, efficient, and safe air transportation system for moving people and goods is an important part of our national infrastructure; to be competitive globally, it's important that infrastructure is developed, maintained, and updated. If we fail in this,
What ?. A windshield wiper system that significantly improves the safety of most types of motor vehicles.
How ?. The system fully wipes off all precipitation (rain, snow, etc.) from the windshield regardless of intensity yet the wiper’s sweeping motion is not perceived by vehicle occupants.
