With any new thing, there is usually a bathtub curve of corrective maintenenance. The initial design is also much the same way.
It happened with some frightening engine problems in the A380 Super Jumbo jet. Such discoveries are to be expected. If flying scares you, then adjust your expectations accordingly. Just remember that even a very well designed, time tested aircraft can still be destroyed by a brief moment of inattention by the pilot, as evidenced by the unfortunate 777 crash at San Francisco airport recently.
What if algae borne of fertilizer runoff that pollutes rivers and lakes could be harvested and used as biofuel feedstock? What if the leftovers could be recycled into farm soil nutrients, eliminating at least some of the need for artificial fertilizers in the first place? Western Michigan University researchers have a plan.
Manufacturers of plastic parts recognize the potential of conformal cooling to reduce molding cycle times. Problem is, conformal molds require additive manufacturing (AM), and technologies in that space are still evolving. Costs also can be high, and beyond that, many manufacturing organizations lack the knowledge and expertise needed to apply and incorporate additive technologies into their operations.
