Telluric Earth-Ground Work At Tonopah – August 2022
Recently, fellow colleague Hakasays had designated time to visit Eric Dollard in Tonopah, and assist in finalizing the Earth ground connection at the lab site. Further testing was accomplished after welding of the water tanks was completed, of which radio frequency was supplied to the connection via a coil setup.

Two New Page Sections Dedicated to Tesla-Telluric Communication & Cosmic Induction Generator Research
Find these tabs on the top menu bar located to the very right.

Telluric Research
This section is dedicated to work being conducted by both EPD Laboratories and associates who are contributing to the development of Nikola Tesla’s Wireless Earth transmission.

Cosmic Light Bulb
The purpose of this page is to present information on experiments involving cosmic induction phenomena, being carried out by EPD Laboratories and relating associates. This section contains images and pictorial detail of special formations occurring in high vacuum and gaseous environments.
Eric Dollard’s presentations at the 2020 Energy Science & Technology Conference now available!

- Alexanderson Antenna Coil Scale ReplicaThe following images depict the first attempt of replicating a potential-shunt coil, as employed in the original Alexanderson Antenna transmission design. Such antenna configurations were employed in Bolinas California, with one example (Grimeton SAQ) still in operational status. The potential coil replicated, shown in figure 1, consists of an eight foot wide by 6 foot […]
- Shadowgraph Tube – Emission PatternThe following figure represents the emission pattern of rays emanating from a Tesla style Shadowgraph Tube, suspected to be producing the effect of radiant matter via a mono-heated cathode electrode of Aluminum. Measurements were obtained with a standard GM tube at varying distances, indicated by the circular lines measured in twenty foot intervals. The top […]
