I see you want to base the work of Nikola Tesla? This is the greatest scientist and if you manage to renew its technology, it will be a breakthrough in the field of energy.
I can't figure out how graphene is connected to Nikola Tesla,or if you've found the lost secret works and patents of this great scientist.
I also still do not understand what the point is, and how they claim to such technologies, most likely a patent has been bought.
I think that it is unlikely that such information will be revealed to you! This is very confidential information!
