Drop in your craziest set of ideas eventhough it might not sound feasible.
Let me drop mine,
1.) I badly want to travel in time to meet Ramanujam. 😀
2.) I would like to produce infinite amount of electricity with the least input possilble.
3.) I would like to provide the world with infinite Wi-fi bandwidth.
4.) I would like to design a motor which should run with no inputs.
5.) I would like to travel to any place of choice with just a clap.
