I am interested in very early inventions that allowed energy to be stored and released after a delay even it's just a short time. With "invention" I mean a novelty that is the result of humans' intellectual creativity. Someting that cannot just be done like throwing a stone but requires ingenuity and/or experimentation. A bow is better. A fly wheel better still.
I am aware that it is unlikely to find a proven first use of such inventions. Still, I am interested in what history knows about it's early uses.
My current assumption is that the first invention to store energy was the fly wheel. And one of the first uses or probably THE first use of a fly wheel is pottery. One site states without providing sources.
The first potter’s wheel is believed to have come from Sumer in 3129 BC, although there is evidence that points to other places of origin. Precursors to the wheel started appearing as early as 4500 BC though, so an exact date is likely impossible.
Though the date 3129 BC seems questionable (how could it be determined so precisely?) the rough date and origin are confirmed by the Encyclopaedia Britannica.
Handmade pottery has been found at Ur, in Mesopotamia [...] dating from a time soon after the Flood (about 3000 BCE), was wheelmade decorated pottery of a type usually called Al ’Ubaid.
- Are these sources correct and are there better ones?
- What about other regions of this world? E.g. the Chinese were famous for their pottery for a very long time and it only seems reasonable to assume that fly wheels were invented in Asia independently from teh middle east.
- Are there any other uses of fly wheels that date back that far?
