Free Electricity from Air Using Tesla Radiant Energy – OA70 / IN34 Germanium Diode Circuit Explained
Free electricity from air is one of the most searched alternative energy topics inspired by Nikola Tesla radiant energy research. While unlimited free energy is not scientifically proven, it is possible to detect and harvest extremely small amounts of atmospheric electrical energy using simple circuits with OA70 or IN34 germanium diodes.
This in-depth guide explains the theory, history, circuit design, safety, and components required to build a Tesla-inspired radiant energy experiment suitable for education and research.

This article is for educational and experimental purposes only. The circuit described does NOT generate unlimited or over-unity power. Output energy is extremely small and intended only to demonstrate atmospheric electricity and diode rectification principles.
What Is “Free Electricity from Air”?
The term free electricity from air usually refers to harvesting naturally occurring electrical energy from:
- Atmospheric electric fields
- Earth–ionosphere voltage gradient
- Ambient RF (radio frequency) energy
- Electrostatic charge in the air
This energy already exists in nature but at very low power levels. Special components such as germanium diodes (OA70 / IN34) are used to capture and rectify these weak signals.
Nikola Tesla and Radiant Energy Theory
Nikola Tesla proposed that the Earth and atmosphere form a massive electrical system. In his patent “Method of Utilizing Radiant Energy”, Tesla described:
- An elevated metal plate (antenna)
- A capacitor for charge storage
- A rectifier to control electrical flow
Tesla believed sudden electrical impulses and environmental radiation could be accumulated and converted into usable electrical effects.
Why OA70 or IN34 Germanium Diodes Are Used
Germanium diodes are essential for radiant energy and atmospheric electricity circuits because they work with extremely low voltages.
| Diode | Forward Voltage | Application |
|---|---|---|
| OA70 | ≈ 0.2V | Radiant energy, signal detection |
| 1N34 / IN34 | ≈ 0.25V | Crystal radios, energy harvesting |
| Silicon Diode | ≈ 0.7V | Not suitable for weak signals |
This low forward voltage allows OA70 and IN34 diodes to rectify tiny atmospheric or RF signals that silicon diodes cannot.
