For example I can take a few water batteries and recharge 2 AA rechargeable batteries. Dont seem nothing fancy or any form of overunity there right. But what if I said I can do this over and over for years charging seemingly countless AA rechargeable batteries all the while using the same water batteries I started with to charge them. Of course now I have evolved the water battery to drycells but the point is still just as valid. See how overunity can be strange and hidden in ways many dont see.
