Where can I see unrealized, fantastic gadget concepts?

Question

Iron

Hello!
Please tell me, are there any sites on the Internet where they publish the concepts of various, not yet implemented, or maybe fantastic gadgets?
For example, I often see successful projects on Kickstarter, such as a multi-tool for a bicycle, headphones with ears and lights, smartwatches, a hoverboard, and other equally interesting projects.
I would like to read and look at similar concepts in order to come up with something of my own and implement such a device.
Thanks a lot!
