What’s your vote for the most ridiculous, overpriced, and useless tweak?


My vote: Furutech Outlet Cover 105 NCF $220, with “special crystalline material that has two “active” properties.” https://www.thecableco.com/outlet-cover-105-ncf.html

Pop quiz  🤗 If the real Schumann frequency wavelength is 25,000 miles how does the Schumann frequency generator produce a frequency of 7.8 Hz in the room? Hint - the length of the antenna required is proportional to the wavelength.

the schumann generator emit an acoustic wave, then the generator transform the electro magnetic wave of 7 .8 hertz in acoustic wave correspondant signal ? is it correct? 

For the antenna: the speed of light divide by the frequency of the schumann wave will give the length of the correspondant antenna modulo some fraction to obtain a small antenna... Is this make sense?
