    I think I’ve worked it out, after some discussion in another comment thread.

    This contraption probably has a high centre of gravity and would tip over backwards if you accelerate too fast. They probably worked out a wind turbine on the top spreads the acceleration force and reduces this problem. The turbine is not for generating power, it has a motor and is used to give some thrust to the top.
