I applied today for ARPA-E funding for Ballistic Circuit Breaker

Excerpts from the Application I filed today:
title: HVDC Transmission Ring with HVDC Circuit Breakers to Assure Redundant Linking of Regional Generation and Storage for Grid Stabilization


HVDC rings have the desirable property that they have intrinsic redundancy; any two taps are connected in both directions. Eckroad (US patent 7,518,266) shows only three DC/DC choppers in his ring buss (containing 17 total taps). This requires blacking out multiple power taps between the choppers in a fault. We propose a DC ring as suggested by Eckroad, but with DC ballistic circuit breakers on the main loop, between each pair of taps.
