ELI5:Why did Nicola's Tesla theory of Clean Energy never got developed, did it lack scientific credibility?

I have been reading lately about this matter on the internet and different books I found, and from what I see it was a theory of huge potential, that never got scientifically rejected but simply died away with time and other methods were developed further. 
Is it possible that we are ignoring something so valuable?

Nikola Tesla had a lot of unusual ideas, some of which were more practical than others. For example, he did not believe in radio waves. Although he made some important advances in electrical engineering, a lot of his claims were never technically demonstrated or explained in a cohesive way. Without any known principles to be tested, those claims don't really have any use. What specific idea did you have in mind?
