“After & Before” rather than “Before & After”!

For so many years, we have always  seen, heard, used  and/or  follow the term “Before & After” to convey a message in persuading  an audience  about  advantageous of a certain method or procedure for comparison purposes . However, in my Power Point Presentation of a very exceptional project (Development of the First Largest Group of 10-Existing Road Improvements in 20-2011) on October 25, 2012, I thought to do something different, in order to leave a long lasting memory of the presentation for the audience. Therefore, I began from the last slide-shot # 39 toward the beginning which happens to become “After & Before” photos and messages rather than the normal “Before & After”.   Subsequently, this method of “After & Before” worked out very well, since audience did not leave the room during my presentation and also some of the students posed a number of very good questions to me after the event. Accordingly, I would like to encourage students to consider using an out of “Norm” approach in their projects and have an audacity to be a pioneer, as much as possible.

Thank you for your attention.

Induction Charging Comes to Public Transit

Induction Charging Comes to Public Transit

Say goodbye to catenary wires. Utah State University has unveiled an electric bus that charges through induction, topping off its batteries whenever it stops to pick up passengers.

Designed by USU’s Wireless Power Transfer team and the Utah Science Technology and Research initiative’s Advanced Transportation Institute, the prototype Aggie Bus is already on the road. It uses the same wireless charging principle as an electric toothbrush or a wireless smartphone charger, except optimized for a massive public-transit vehicle.

As in all modern inductive-charging setups, a transformer is “split” between the bus and a charge plate under the bus stop. When the bus drives over the charging plate, current flows with no physical contact required. Engineers at USU designed their system so that the Aggie Bus can be misaligned up to 6 inches from the charge plate and still get 25kW of power and 90 percent efficiency from the power grid to the battery.
