But the structure is vitrified ceramic not the dielectric. Its a very
hard brick with no voids, the dielectrics break down does not matter.
Its also in a solid box that negates any easy penetration. I've
corresponded with Dick Weir the principle of EEstor. Its wrapped up
very well and the switching means that if one cap goes its isolated
to that cap.
Let's do a thought experiment here and we'll see. 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.
