Ole,
Yes, you are right about GHz frequencies and how difficult it will be to shield from them; The 5G frequencies will be so small like weapons grade and we won't be able to protect ourselves from them and when they decide to cook us we will be history.

Hi Mick,
"What is Tesla's mohm impedance generator?"
That generator is covered in US patent 447920. Here Nikola Tesla is explaining it:
https://books.google.dk/books?id=KRg9HWakBmQC&pg=PA3&lpg=PA3&dq=patent+447920&source=bl&ots=0UjH_D9THu&sig=jQtpZRKMlKElkUz5t_BwmJJ_8Tk&hl=en&sa=X&ved=0ahUKEwi5xqaG-YTbAhXO2KQKHRHfCYwQ6AEISTAH#v=onepage&q=patent%20447920&f=false
The output resistance of the armature was 0.5 Ohm (500 mOhm). The current density could be 30 A/mm2 because of its exceptional cooling.
It was with this generator that Tesla discovered the stinging effect of the electric field generated when a short made the wire explode. This gives a very high voltage flyback pulse with the very high peak current that suddenly has nowhere to go without creating a high tension electric field. The stinging was felt behind glass or metal shields. The metal shield was earthed but not totally enclosing the person to be shielded. With the knowledge of EMC technology of today this is not a proper way of shielding HF fields. The ground wire itself has enough inductance to be 'soft' by having high impedance to high frequency signals. Even a Faraday shield has to be of fine enough mesh to not let the waves through. A mobile phone with its GHz frequency let the waves go through holes of bigger size than the wavelength.
The stinging effect was what made Tesla start studying HF of high voltage.

Ole,
You wrote:"Braking a very low impedance generator like Tesla's mOhm impedance generator by shorting the output releases much of the stored mechanical rotational energy in a fraction of a second"
What is Tesla's mohm impedance generator?
