The Italian researchers have came up last month with a new theory for explaining the Hessdalen Phenomenon. It suggests that the local characteristics of the valley lead to the production of cold plasmas and/or ion bubbles, by means of chemical effects and thanks to the self-consistency due to the polar properties of water.
However, the document states that this paper does not aim to provide a solution to the origin of the Hessdalen Phenomenon and that ”…to better investigate this working hypothesis, future campaigns will have to focus on the acquisition of wider and higher‐resolution fully calibrated spectra, exploiting the professional instrumentation usually employed in astrophysical observations…”
The English paper can be downloaded from the Italian Committee Project’s website:
‘HESSDALEN: a perfect “natural battery”
Abstract: After 12 years of thorough research, we believe we added an important element to the comprehension of the mysterious phenomenon. The valley shows electrical anomalies, Moreover it has peculiar geological and mineral characteristics. Such features have helped us to put forward a working hypothesis on what we here call “natural battery”, an electrochemical That model could be tested conceiving proper experiments and field measurements.
