So the question I have been asking myself is "What makes a powerful question?" And Wes Saade helped me realise that at a high level there is a very simple answer.
There are everyday questions and then there are powerful questions. What is the purpose of a question? Well to solicit an answer of course. If I ask "What time is it?" Someone might tell me "ten past two". I have asked my question and received an answer. But are questions that solicit simple informational answers powerful questions? Clearly not.
So what is different about a powerful question?
A powerful question is one that compels others to think.
There is clearly more to it as Wes explains in his article How to ask powerful questions but this is the key point.
