A patent monopoly on that hypothetical power generation device would have the potential do a lot of harm actually… Bankrupt many companies, causing the loss of jobs generally around the world and a potential expanding economic shock matched to the rate of production of the new devices Cause the complete devastation of smaller sized communities (villages and towns, very small cities) where the majority of employment is directly in an energy related resource extraction capacity or in supporting jobs maintaining equipment for or supplying services to these primary resource industries The lack of externally needed power supply like diesel fuel or surface supplies for solar farms would enable more people to take up mobile or alternative living situations (van life, mobile homes, camping with appliances) as the need for a house to plug in appliances is one of the anchoring factors in real estate economics which could be the best thing for people in general but also another potentially large scale economic shock.
