Sorry, but energy cannot be created or destroyed.
You cannot create free energy, and neither does free energy
exist.
These are fundamental laws of physics, and certainly, there is no
way to charge 2 batteries with 1, for that would violate the very
basics of of the laws of conservation of energy. The only way that
is almost achievable is to use one battery to partially charge 2
other identical battery, but that is only ideally, for in real
life, there is the element of inherent inefficiency present.
Simply to put it, the "extra" energy must be coming from somewhere
and since you mentioned nothing about nuclear fission/fusion, or
any chemical reaction, i would assume that you are claiming these
"extra" energies are pulled from thin air. This is not possible,
for if you claim so, you are inadvertently claiming that you can
create matter out of nothing, according to Einstein's E=mc^2
law.
You are making a very huge claim here. Being able to create matter
out of nothing, and i wouldn't be surprised if it gets thrown out
the patent office, for this is too absurd and you'll be possibly
the greatest scientist and inventor ever if it were true. In fact,
you'd be the first person in the world to create matter out of thin
air.
But alas, i remain a skeptic.
Besides, are your researches even peer-reviewed? For that would
surely be a good gauge of truthfulness and honesty.
All in all, I would say that you are most likely trying to amass
investment from clueless investors. Scamming, in other words.
