Can a Capacitor Recharge From Ambient Static Electricity?
$begingroup$ DJG, Look up the phrase "intrinsically safe" on google with the added word capacitor or capacitance to help out. Stations that provide pumps for car fuels that are volatile (like septane, octane, and nonane -- gasoline in the US) cannot have more than a certain amount of capacitance and must include intrinsic series resistances (usually.)
What material can I use as a dielectric in my own high voltage capacitors?
Distilled water: It has a breakdown voltage of 65 to 70 MV/m . The problem is the forming of ions within microseconds after applying the voltage which lead to an immediate breakdown. This can be prevented by keeping the water flowing and deionizing it somehow.

Can Static Electricity Charge A Battery? Methods, Risks, And
No, static electricity cannot effectively charge a battery. Static electricity involves the buildup of electric charge on the surface of objects, while batteries require a flow of electric current for charging. Static electricity can create a voltage difference, but it does not provide a continuous flow of current necessary for charging batteries.
Electrostatically charging a capacitor
The electric charge of an empty capacitor and a full capacitor are both 0. If you charge up a piece of PVC and touch it to a floating capacitor, it won''t accept any more charge than any other piece of metal of the same size. The reason capacitors can store so "much" is because you''re removing charge from one plate and depositing it on the other.

Static electricity, it''s all capacitance? | All About Circuits
So as a summary: the theory of static electricity all comes down to capacitors connected together, that are charged to diferent voltage potentials at different capacitance values leading to the different charges. If two "capacitors" are connected with one "lead" it will be equivalent of having stray capacitance between the two floating "leads".

Electrical breakdown
Electrical breakdown in an electric discharge showing the ribbon-like plasma filaments from a Tesla coil.. In electronics, electrical breakdown or dielectric breakdown is a process that occurs when an electrically insulating material (a dielectric), subjected to a high enough voltage, suddenly becomes a conductor and current flows through it. All insulating materials undergo breakdown

6 Frequently Asked Questions about “Can static electricity break down capacitors ”
Why does a capacitor have a higher charge than static electricity?
This charge is only slightly greater than those found in typical static electricity. Since air breaks down at about, more charge cannot be stored on this capacitor by increasing the voltage. Another interesting biological example dealing with electric potential is found in the cell's plasma membrane.
