Invention?

Question

Is there any reasonable invention that could be made that you would like to see...Not like some automatic homework helper or something like that
Example: A book page turner

Answer 1

Transportation - Car that runs on something economical other than oil. Also, I'm still waiting for a car that drives itself.

Internet - An image search engine that can search by description (actually match the picture image with the search, not just look for pictures with the search word in the title).

Household - House with moveable walls and appliances so you can adjust rooms to your need

Communication - A cell phone that can have multiple numbers on the same phone
