Hi. i've looked into this & associated areas a lot.
i don't doubt that the V2K technologies exist, but i think it's a more complex question as to what extent these technologies are being utilised? & who is a genuine TI.
There are various tachyon field generators & assorted technologies claimed to do certain things? My own interest has been in Radionic/Rife areas - understanding everything in terms of frequency, energy & vibration.
i do have a Tachyon Generator - But i can't find the place on-line i got it from.
Have heard of people constructing faraday cadges & using lead/copper cases.
i like certain crystals - black tourmaline, & many others can be used.
It's controversial, in depth & expansive areas.
Jammers can be effective but are often illegal.
A thread here on Radionics/Rife technology -
