I would like an alarm clock that could turn time back.

It would wake you up and you would say: “Not now, I would like to sleep for 45 more minutes. “

And it would reply, “No, problem, 45 minutes coming up.” And the alarm clock would just wind time backwards 45 minutes so that you could sleep more but still wake up as early as ever.

Kind of like a Hitchiker’s Guide to the Galaxy gadget, isn’t it?

I bet I would get richer than Bill Gates 😉
