Where you learned that no field electron emission?
S*


We don't operate our antennas in the voltage range where that becomes
a problem, like Tesla did.


The field electrons emission take place at each voltage.


No.

You did not read the material.

From http://en.wikipedia.org/wiki/Field_electron_emission

"Field emission in pure metals occurs in high electric fields: the gradients
are typically higher than 1 gigavolt per metre and strongly dependent upon
the work function."

Do you have any clue what it takes to get a gradient of 1 gigavolt per metre?
