there was a steel manufacturer that did an MOU I did not know there was another corporation that had.
Still a MOU from my understanding and having been burnt several times with companies that have had them is that an MOU is not worth the paper it is written on as it is non binding.
I would rather see Multi billion capped GE or similar taking a shareholding in this micro cap company if this tech is so game changing.
Why have they not taken a shareholding?
