Manufacturing an internal combustion engine from extruded aluminum alloy rather than conventional casting offers many benefits, including big size and cost savings. So says Power Beat International Ltd., a research and development company based in Hamilton, New Zealand. Powerbeat's ALU-X(TM) engine employs interlocking sectioned extruded profiles to form the engine block. Replacing one-piece cast blocks, the company claims, allows engines of different capacities, cylinder numbers, and stroke lengths to be made from the same parts. Engine assembly is quick and easy: Tie bolts hold stressed components in compression, eliminating the need for load bearing threaded holes within the block; tee slots incorporated into the extrusion profile allow simple attachment of auxiliary components. Other benefits include superior grain structure for accurate bores and finishes; lower capital costs, higher production capacity; high power-to-weight ratio. Power Beat International is currently developing 200-cc versions of the ALU-X to suit the small engine market. Contact Evan Bydder at ebydder@powerbeat.com or call +64-7-843-0011.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
