The OP said they'd invented one. Maybe they have. But I don't know of
a use for it. An inventrion is only worth pursuing (to make money) if
it has a substantial use and is better for some applications than the
existing technology - better often meaning cheaper. If you can come up
with a real use for it, where it has significant advantages over
todays methods, great.
IRL a lot of new ideas have disadvantages with them, and are not
commercial goers because of them. For those, patenting would be a
money sink. I would look at possible commercial uses for it next. If
there are none, keep designing.
If you decide it has no commerical future, it might be interesting to
hear about it. I have 2 different electrically controlled variable
caps (just on paper), and there are various issues to do with the
input/output arangement on all of them.
Do you come up with new ideas regularly, or is this the first of
