A METHOD OF GASIFYING A BODY OF FLUID HAVING ITS UPPER SURFACE EXPOSED TO A GASEOUS MEDIUM WHICH METHOD COMPRISES ROTATING IN A HORIZONTAL PLANE AND AROUND A VERTICAL AXIS, A CIRCUMFERENTIALLY SPACED SERIES OF BLADES EACH OF WHICH IS RADIALLY SPACED FROM SAID AXIS, EACH BLADE HAVING A VERTICALLY AND HORIZONTALLY CURVED FRONT FACE WHICH IS CONCAVE TOWARD THE DIRECTION OF ROTATION, SAID BLADE HAVING A FRONT PLOWING END AND A RELATIVELY ELEVATED REAR UPPER END EDGE, SAID ROTATING BEING PERFORMED SO THAT THE LOWER FRONT ENDS OF SAID BLADES DIP BELOW THE OPERATIVE SURFACE LEVEL OF THE BODY OF FLUID TO A DEPTH WHICH IS A MINOR FRACTION OF THE DISTANCE BETWEEN THE PLANE OF ROTATION OF THE UPPER ENDS AND THE PLANE OF ROTATION OF THE LOWER ENDS, WHEREBY THE ROTATING BLADES PLOW SEPARATE PORTIONS OF THE UPPER LAYER OF THE FLUID AND THEN CAUSE SAID FLUID PORTIONS TO BE SPREAD THIN ON THE CONCAVE SURFACE AND THEN CUT ON THE ELEVATED UPPER EDGE AND PROJECTED UPWARDLY SO AS TO FALL BACK ONTO THE MAIN BODY OF LIQUID IN A RECEIVING ZONE WHICH IS LOCATED GENERALLY EXTERIOR OF THE CIRCULAR PATH OF MOVEMENT OF THE BLADES.
