The project should be useful to the people in the country or region to which it is targeted. For example, if we are planning to do a room heater in a place where the average temperature is nearly 38 degrees centigrade, it is meaningless. Normally, a project should be in the form of a solution to the existing problem for a specific geographic region.

Good old valve radio
My grandfather had a very old radio, much bigger than today’s micro oven. He used to decide which station to be tuned in to and which program to be tuned in. It was a valve-type radio and it used to take some five minutes to get the valves to get heated up. Before that, we were unable to listen to anything. That was the technology at that time, about nearly 40 years ago when I was a school kid.
