I didn't believe you when reading this sentence. But after competing your post I would say you were very fair.

I too had an idea of a UPS when I bought my first rechargeable battery years ago. I got the idea of a hybrid car when I was playing with my first dynamo. As you rightly said, they don't count. Atleast 1000s of others would have had the same idea, well before me as well, andd they implemented it.

On the other hand Google, Facebook, Amazon, why Bitcoin are also not original ideas. They were the best implemention of the existing ideas.
