Operation of Electric Motors from the Atmospheric Electric Field

American Journal of Physics, 1971
An electret-type electric motor and a corona-type electric motor have been constructed for operation from the earth electric field. The power is delivered to the motors by means of simple earth-field antennas with radioactive or sharp-point collectors. Initial results on the operation of the motors are reported.

Global variation in the atmospheric electric field

pure and applied geophysics, 1972
An analysis of the global nature of the atmospheric electric field is presented on the basis of comparison of measurements on the research vessel, Hakuho-Maru, on the Mid- and South-Pacific Ocean, with those at Syowa Station in Antartica and on two vessels on the Mid-Atlantic Ocean.

Diurnal variations in the atmospheric electric field

Journal of Atmospheric and Terrestrial Physics, 1976
Abstract The diurnal variation of potential gradient at a continental site in the Southern Hemisphere does not follow the established pattern for Northern Hemisphere continental sites, nor does it accord with the diurnal variation found over the oceans and in polar regions. There is good correlation between potential gradient and space charge density

ARES, atmospheric relaxation and electric field sensor, the electric field experiment on NETLANDER

Planetary and Space Science, 2000
Abstract The conditions which prevail in the atmospheres of most planets in the Solar System, in particular the telluric ones, are likely to give rise to their electrification. The resulting processes, which are of major importance for meteorology and climatology on Earth, may also be significant for atmospheric and surface processes on the other ...

Electric fields in the solar atmosphere: A review

Solar Physics, 1991
A review is presented of remote sensing techniques which measure the electric field component transverse to the line of sight and achieve a sensitivity range of 5-10 V/cm. Three models are shown to predict quasistatic, macroscopic values of E(parallel), the electric field component parallel to the magnetic vector, beyond the sensitivity range ...

Electric field generation in atmospheric convective cells

Journal of Atmospheric and Terrestrial Physics, 1992
Abstract An electric field generation mechanism in the atmosphere, formed by the joint action of friction and gravitational forces upon the charged aerosol particles captured into a convective cell is considered. It is shown that the electric field structure may be found by a self-consistent approach, taking into account the influence of the electric

Measuring atmospheric electric field using novel micromachined sensor

2011 6th IEEE International Conference on Nano/Micro Engineered and Molecular Systems, 2011
A new type of micromachined electrostatic field sensor (EFS) that can be used to measure atmospheric field has been demonstrated in this paper. The sensor structure is designed to work at resonant frequency for maximum sensitivity to electric fields. SOI (Silicon on Insulator) micromachining technology was used to fabricate the sensor. The sensing area

Rainbows in strong vertical atmospheric electric fields

Journal of the Optical Society of America A, 1988
The effects of strong vertical atmospheric electric fields and electrically charged raindrops on the primary rainbow are considered. A vertical electric field alters the bow by stretching the raindrops vertically. The effects may be visible only for the extremely large electric fields (E > 105 V m−1) sometimes encountered in thunderstorms. The electric

Atmospheric Electric Field Effects in Cosmic Rays

2004
Discussions on the possible acceleration of charged particles by atmospheric electric fields in periods of thunderstorms started to appear in the scientific literature many years ago. Wilson (1925) assumed that electrons in thunderstorms clouds can be accelerated up to very high energies, as in CR. There were many attempts to observe effects of charged
