Quadcopters for Humans


The people at Siemens have developed a very powerful but lightweight electric motor.   With 4 of these you could make a big quadcopter that could carry some number of humans. We will see humans on quadcopters in the next few years.  The prop below is sized for a fast moving airplane.  For a slower quadcopter the blade would be another foot or two across and a little flatter angle.



   For short times you could use batteries or long times a turbine/generator.   If all you want to do is go from a floating home 12 miles out to land and back, batteries would probably work fine.  If you want to go far, then turbine/generator will be needed but cost more.
