Is there anything that you would like to have but it hasn't been invented yet? What would you use this thing for?

I would like а thing that would teleport me to any place I want. It would save а lot of time (Я бы хотел иметь такую вещь, которая переносила бы меня в любое место, в которое я захочу. Это бы экономило много времени).
