Toroidal propeller: More speed, fuel savings claimed Is a toroidal propeller the next big thing in boating? Sharrow Marine, creator of the Sharrow Propeller, thinks so. Four years of independent and factory testing have proven this design bests standard blade technology by providing: significant speed increase at mid-range RPMs, up to 30% greater fuel efficiency, less vibration, dramatic noise reduction, more reverse thrust, superior handling in tight turns at high speeds, and more. The Sharrow Propeller has won numerous innovation awards from both boat shows and highly respected marine publications. Learn all about the development of this very cool technology.

Choosing between brush and brushless DC motors: What are the tradeoffs? Designing a system that involves motion and performs as intended requires choosing the right motor. The most fundamental decision involves commutation type. In some cases, mechanically commutated brush motors provide the best solution for the budget. In other cases, only brushless DC (BLDC) motors will do. Allied Motion provides a comprehensive review of the technology, along with tips and tricks for choosing the right solution for a given application. Read the whitepaper (no registration required).

What is 3D-MID? Molded parts with integrated electronics from HARTING 3D-MID (three-dimensional mechatronic integrated devices) technology combines electronic and mechanical functionalities into a single 3D component. It gives engineers the power and freedom to shrink components, optimize space, and provide higher overall functional density -- while offering the same or more capabilities as in larger devices. HARTING's tagline for the tech is, "Like a PCB, but 3D."

| Everything you need to know: Electric vehicle tires | |
| What happens if you put a "regular" car tire on an electric vehicle (EV)? Engineering Explained's Jason Fenske covers that and more when he gets deep into why EV tires are different than internal combustion engine (ICE) car tires due to weight, efficiency, noise, and torque demands and other characteristics. You always learn something from a Fenske video.
