It would seem to me that the mechanical stresses would eventually weaken the dielectric. Correct only if the structure is not prestressed to take the cycling. Sensors in the matertial could detect an log the stress. There are als selfhealing matterials now that cycle in the reverse to the stress. If a fuel tank has the same energy does they mean its as dangerous as dynamite? IMHO, this is a nonsequetor. The energy in a Mars bar or a gas tank is potential, it lacks the other half, O2, and the flame front of a fuel O2 reaction is slow. And the electrostatic equivilent of controling O2 is controling the earth. Or controled discharge of the stressed section of the block into the load. Use the most stressed section first. No because the reaction has other variables: flame speed and oxygen supply in the case of fuels. In the case of EEstor caps its the fracture resistance of the ceramic, the percentage of the caps broken in a breach and whether there is a earth available and the temperature of any arc relative to thermal properties of adjacent materials. It would seem to me that the entire structure would degrade over time with the mechanical stresses of charging - discharging and road vibration. When a spot breaks down there will be a big stress on the surrounding structure. The big factor, IMHO, is the instantaneous release of electrical energy. 3.5 KV is some potent stuff. IMHO, It depends on whether the rest of the energy is a package will flow into this fault. Reportedly their lab samples have been cycled thousands of times. No reported Booms. The things will be subjected to a destructive testing. Yes I would like to be behind some balistic plastic while watching the test but it should be fun to see. Military people are in the Eestor loop. Their tests of field durability include shotting thing to see if the go boom. --- http://USFamily.Net/dialup.html - $8.25/mo! -- http://www.usfamily.net/dsl.html - $19.99/mo! ---

A Milky Way bar contains more energy than a stick of dynamite. A tank of gas in that SUV contains about a megawatt. My grandson has more energy than a full SUV and often explodes.

Thanks my point exactly its not how much energy but how fast it can discharge. The grandson probbably holds that record.
