separating the mop from the sand is quite easy: just add enough water so the mop starts to float (while stirring of course). Same as getting wood chips out of sand...basic separation technique wich they teach in primary school
MOP has machines. MOP CAT, MOP CANON, and probably some things we do not know about yet. I will rewatch the video to see how the oil and sand and MOP are removed from each other.
I do not want to say they do not have machines because we do not really know what they have until they tell us. MOP could also use existing equipment to work with their products. Weed skimmer for example. Everything that Thad Allen has been talking about MOp has been talking about for months if not years. I understand what you are saying but MOP may not be showing all that they have yet.
AT ABOUT 3:30 Diamond starts to explain how this process works
