What would I do with that? I would like to believe that I could end suffering, at least in some area of life, but realistically, it would be a task that couldn't be fulfilled.
I wouldn't know how to do this but this would be my goal. I would gather all of the secret knowledge of Tesla, and every other scientist that made a great discovery in free energy, and I would have great minds or AI or both compile all that data into a working system to share with the.entire world. Because if energy was free, there would be no costs to agriculture, because the only real cost is energy consumption. That in and of itself would end world hunger, end homelessness, and allow people who really want healthy humans to work on preventative care through diet and lifestyle. Goodbye pharmaceuticals! No one ever had a need for your poison. only clean food, no chemicals. no plastics. close every petrochemical plant, oil distillery, and stop spraying chemical in the air we breathe. That is what I would do.
oh yeah, and have the biggest animal rescue coalition ever imagined. every domestic and wild and livestock animal would have what it needed.
