In researching electric
drives for a 50' cat I always liked the concept
of the system developed by African Cat called Green Motion
GREEN MOTION: electric, fossil free, marine drive, and propulsion system
where the drives pivoted out of the water
mounting above the water
line. Are they still in business?
Of course batteries
alone or in conjunction with a generator
could be used.
Are there any other systems that can be retracted from the water, can be used as a water generator
, retracted for zero drag while mounting above the water line?
