Watched a weird program about inventions with Wallace and Gromit and there was a short film about a teenager from Malawi who decided to bring electricity to his remote village

Humbling

Fast forward to about 7.25 minutes in the program

We watched that and to think of how he did it with just bits and pieces he found lying around. A very clever young man.

It is amazing.

I have so many resources available to me but I always find some excuse to read books about everything and not actually build anything.

I don't have the time. I would, if I had a workshop, when I get this tool or that tool I will be able to change the world, I need to buy another book.

I need to pull my finger out

I watched that as well, very inspirational. Can anyone point me to a link which shows the basics of how you can do it yourself. Am I right in thinking you need a DC motor to run in reverse?

There are loads of videos about building wind turbines on youtube.

I don't think you have to run the motor backwards. But I think pretty much any DC motor will act as a generator if you spin them. It is just coils of wire running within a magnetic field.

Or you could build your own permanent magnet alternator out of copper wire and magnets
