Finally the earth - atmosphere system forms a huge capacitor. The earth's surface forms the lower plate and the so called electrosphere forms the upper plate, charged to about 300,000 volts. The electrosphere extends over the whole globe at about 50 Km up and is formed from conductive ions in the air.
The Earth-ionosphere (EIC) capacitor concept is widely known and has been used in atmospheric electricity for a long time. The EIC model cannot adequately account for key observations in atmospheric electricity; therefore it is inapplicable.
Capacitance of different types of capacitors – Spherical, Cylindrical, Parallel plate capacitor, isolated conductor. Energy stored in a capacitor. Electrostatic potential and potential energy. Earth is a spherical capacitor. Let's derive the formula for the Capacitance of Earth and find its value in microfarad.
A simplified scheme of the Earth-ionosphere spherical capacitor. The capacitor shells are separated in altitude by h ≈ 70 km, with the upper shell coinciding with the bottom of the conducting D region ionosphere.
The EAC is an uncommon spherical electrostatic capacitor which has as inner plate the conducting Earth surface charged at – Q, and as outer plate a height-extended spherical air-shell that has a total space charge + Q distributed non-uniformly across the air-cell, while at the same time this air-cell acts also as a leaky dielectric.
This concept, which is known as the “Earth-ionosphere capacitor ” (EIC), was first conceived by Lord Kelvin (William Thomson) in 1860 and developed further by C.T.R.Wilson nearly 100 years ago ( Wilson, 1921, Wilson, 1929).

Why dont ev use super capacitors for regen braking
The motor needs a minimum voltage to produce power or it will overheat and stall. This means the capacitor energy below that voltage cannot be used, which turns out to be about 75-80% of its rated capacity (when operated at normal battery voltages). That energy can still kill you, so you''re just driving around with risk.
