.....from a space influenced by a field,appears to be the purpose of this forum,more precisely the gravity field.
A promising exemple,can start with a "crystal radio" ,or even more with a "razor blade radio" (due to his simplicity !),with his free power from a field ,operating without a visible power supply,at:

Detection process ,that makes electric waves audible can be a suggestion to "detect",find out,discover gravity as "falling waves"?!

...as a concept , at : www.veljkomilkovic.com/Veciti_motoriEng.html (http://www.veljkomilkovic.com/Veciti_motoriEng.html)
It seems that the gravity motor (so called perpetuum mobile...) and the inertialpropulsion motor have a common "prime line" related to rotational inertia...
