Goal
Increase rocket altitude by exploiting electrostatic repulsion between a positively charged rocket and the Earth's electric field.
Problem
Conventional rockets are limited by gravity and chemical thrust; the invention seeks to augment lift using atmospheric electric fields.
Concept Summary
The rocket is charged positively (by a Van de Graaff generator or by conductive coatings) so that it is repelled by the Earth's positively charged surface and attracted to the negatively charged region aloft. By controlling surface conductivity, humidity, temperature, and time of day, the rocket retains charge during ascent, achieving greater altitude than an uncharged rocket.
Principles
- Electrostatic repulsion between like charges
- Charge accumulation on conductive surfaces
- Interaction with Earth's atmospheric electric field
- Dielectric dependence on humidity, temperature, pressure
- Magnetic coupling between moving charge and Earth's magnetic flux
