Probably a bit of a long conversation but my day job is to work with new ideas and solutions.
1st thing is to check if your idea is really new. It's a well knows concept that the same idea pops up seemingly randomly in many places. (We understand why). Original ideas are extremely rare. Especially in a highly topical environment like battery theft. There are literally thousands of people coming up with solutions.
2nd, if you feel strong enough about your idea, protect it by using the correct procedures available. Lodging a patent application is no guarantee, btw.
3rd, you need to think carefully about what you want to get out of this; develop your own idea, sell it, start a company, etc.
I'll drop you a message with my contact details and, if you want, we can chat a bit about it. From a Vodacom perspective, I can also give you the details how to engage.
