The company just proved their tech which is making hydrogen using these pannels filled with water and some nano tech. It has great potential and for the next year or two they will be testing it in colab with another company.
In the long term I think it has great potential. Honda is supporting them. If japanese automotive starts using hydrogen (perhaps as a ev hybrid) it could be an awesome green fuel source which will be in high demand.
The panels work with any kind of water (thing waste water repourpose).
I bought a few shares, may be a good idea to get some too.
