Here is my presentation. I will post a video when I receive it from the conference organizers.
I had a spirited exchange with the judges; at one point I cut one of them off who was blathering on with way out of date information on the Tesla/Edison "War of the Currents" that has not been true since 1960!
The SVIEF 2013 occurred November 2 in Santa Clara. I got my booth for free (I won it) and I just learned October 29 that I'd be one of 10 entrepreneurs to present to the whole conference.
There is a backstory to this. Since I was a teenager, I have thought about underground electric pipelines; I got the basic idea of a supergrid from R. Buckminster Fuller when I was a teenager, and I thought of elpipes then, more than 30 years ago. When I studied physics I learned how to calculate the mass of the conductor needed. A lot more conductor is used in an elpipe than a set of overhead lines (from 3-18 times more than equal capacity overhead lines), but not more volume of conductor than will fit comfortably inside a typical gas pipeline. My invention is a high voltage current carrying train, in which the cars of the train are rigid bus pipes, linked through flexible couplings much like rail cars. The track is the inside surface of the pipeline which is just like a gas pipeline with no elbows or tight bends.
The most important application for Ballistic Breakers is in enabling a multi-terminal HVDC supergrid. HVDC Ballistic Breakers will be less expensive than ABB's new HVDC circuit breaker. The combination of elpipes for high capacity bulk transfer and Ballistic Breakers as low cost HVDC circuit breakers are powerfully enabling for a future HVDC supergrid.
