Wow, that's not how it's done.
A large corporation might license the technology (exclusively) and compose and fund their own start-up to further develop the Mantra technology at which time the large corporation buys it back......
or
A large corporation licenses the Mantra technology (exclusively) and develops a product. If the technology is developed enough. Mantra's technology as of today is not (as far as what is publically known). And a large corporation is not going to hire Mantra's people, en masse.
Since Mantra's technology has been around for scrutiny for several years now, it seems option #1 is out.
Since Mantra has yet to display a demo pilot device ERC or MRFC, they would not be candidates for option #2.
They might build an MRFC that would power a electric bike/motorbike which would be affordable and allow better marketing credibility.
Well..............
