When Ed Nauman fires his oxygen-propane cannon, anybody within range of the shock wave will definitely see stars. It's been known to shatter windows 30 ft to the rear! Propane is mixed with oxygen under control of a PIC microcontroller, in a barrel made from a 330 ft³ nitrogen tank and detonated by remote control. It's even instrumented to measure the kaboom — he's recorded 180 dB SPL (think two sticks of dynamite). Gadget Freaks, don't try this near your home (or your neighbor's)!
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.
