Based upon my reading of Vassilatos' 'Vril Compendium'(s) and related works, in order to be complete, a Vril Theory must account for each of the following phenomena in a comprehensible and testable manner. I will continue to post the relevant experiements, video, source material, etc. I may supplement the list, but will keep this numbering:
VT1: Classical Electrodynamics (e.g. conduction, induction, capacitance, resistance, AC/DC power transmission, etc.)
VT2: All the stuff left out of Classical Electrodynamic theory but clearly in the canon (e.g. Faraday's homoplanar generator)
VT3: One-wire transmission of power, in the absense of measurable electic or magnetic fields (e.g. Tesla's magnifying transmitter, Dollard's analog computer)
VT4: Radiant Energy phenomena (Moray, Tesla) including the evolution, transmission, and reception of (net) electrically and magnetically neutral species, and conversion to conventional EM (e.g. with laminated aerial metal plates)
VT5: Creation and absorbtion of photons (e.g. Reichenbach's OD experiements, Vassilatos' description of 'Black Radiance' around grounded iron)
VT6: Disruptive Discharge phenomena (Tesla's quenched spark gap, Gray and Lindemann's "Cold Electricity")
VT7: Evolution/dissipation of matter (e.g. Reich's "Cosmic Superimposition)
VT8: Wireless transmission of power (e.g. Tesla's magnifying transmitter, Meyl's solid state Tesla transmitter)
VT9: Torque effect in high voltage lines
VT10: Neural impulse transmission of photon energy
VT11: Nerve induction between parties over 1 wire
VT12: Transmission of images directly to mind (e.g. Eidetics)
VT13: Projection/absorbtion of vril/orgone/dor to cause atmospheric effects (e.g. Reich's cloudbuster, Trevor James Constable's etheric weather engineering)
VT14: Golden ration electric charge/discharge effects
VT15: Other ORAC effects (e.g. temperature differential effect, relationship to static discharge)
VT16: One wire and wireless longitudial magneto dielectric transmission in excess of C (Dollard, Tesla, Meyl)
VT17: Evolution of classical quanta

In addition, a complete Vril Theory should attempt to address these appendix phenomena:
VTA1: Bilocation, or at least the sense of 'being there'
VTA2: Transmission of regenerative energy along nervous system and between individuals
VTA3: Seeing through walls (gothic cathedrals) or grounded plates
VTA4: Biological detectors
VTA5: Radionics phenomena (influence at a distance, taking pictures of past/current/future forms)
VTA6: Ganzfeld phenoma and related image transmission phenoma (e.g. remote viewing)
