    Web designer and developer Todd Sieling shares his obsession for shoes hung from power lines, which he's been photo documenting for over a decade, and offers some theories about why people do this strange act. Interesting Vancouver was founded by Brett Macfarlane and is organized by Mark Busse, James Sherrett, Lauren Isaacson, and Jason Landry and their team of volunteers. Thanks to Ryan Mah (@Unisonpress), Jana Hanova and Jake Hermiston for video production and Trevor Jansen for still photography. ........................ Interesting Vancouver is a multi-disciplinary conference with no theme. There will be a degree of spontaneity, unexpected moments, and learnings. This is what makes it exciting.

    • Instant Windshield Deicing with PETD

      A PETD-enabled windshield can be deiced in 6-10 seconds from a cold start. Dartmouth Engineering Professor Victor Petrenko and his research team discovered that applying short pulses of electricity directly to an ice-material interface produces some novel and desirable effects. This discovery led them to invent an ultra-fast and efficient method of ice removal and prevention called pulse electro-thermal de-icing (PETD).

            • Non-Slip Footwear & Cross Country Skiis Stick to Ice

              In another configuration, PETD can increase the friction between ice and other objects such as shoes or tires, creating “ice brakes.” The same concept of applying short pulses of electricity directly to an ice-material interface can also be used to control whether ice is sticky or slippery. Electronic friction control for winter sports equipment—serving as electronic brakes or "electric wax"—is thus another application for Petrenko's ice-control technology http://engineering.dartmouth.edu/research/engineering-innovation-for-ice-adhesion-and-friction-control/

                Advantages of VRC Deicing over other technology Ø Inexpensive switching electronics Ø VRC uses existing available line power Ø No additional source power required Ø No service interruption to customer Ø Ability to deice a line section-by-section Ø Fast. Approx 5 minutes per 10km Ø Works equally well on DC and AC lines Ø Ability to monitor icing conditions (ice detection) Ø Low energy. Uses less than 5% of transmission supply. Ø High stability without causing line imbalance. Ø Anti-icing mode for both transmission and distribution lines Ø Excellent performance in the harshest weather conditions
