Middle presentation (chat with Anders Smith)

Basically this talk was more to re-define what I want to do? 
We discussed  some ideas:
Solve miner's problem in an emergency situation.
I need to go back to the mine and analyze more the user.
to know the size of the thing.
It was a very short conversation but definitely I need to go back one step behind to get more information about the final user and the main concept.
