All the major inventions and innovations were not accidents. They were first planned before giving them a proper structure. It is the necessity that made them plan for those things. So we have the saying that necessity is the mother of all inventions.
Now if you can think of some real necessity in life, then you can be creating some cool fascinating technological gadgets for your future. If not creation you can at least design them for the technical scientists who have knowledge but don’t know what to make. Yes, it is a fact that there are many scientists out there still in search of a project that can make them popular, though they have much knowledge on how to make them.
So, all you have to do is give ideas to these people through some way like blogs. Think something realistic, not over fictious gadgets like flying saucers or time machines.
