Nice idea, with strong potential for improvement

The construction goes quickly from equip, but here creeps already the first bad feeling of mediocrity a. The wind turbine operates at the end of very lego way dahingeschustert (where Lego would have been to probably really prefer here!).
The functionality adheres badly in limits.
The gearbox is a botch and offers no comfort.

Disillusionment then brings the latest small electric motor. He is so stiff that it is hardly fluent generate electricity in order to flash the attached LED. The Kunstoffgestänge twisted strongly until the generator finally yields to the compulsion and again makes a small leap forward, to then stop again. Here so much force must be applied even in the smallest transmission speed mode manually that at an operating via wind is not to think.
Presently the work is boring around gathering dust in the apartment. Only interesting to look at, play (remotely) does not need with want.
Although I would rather prefer the Deco then a more realistic model with fan function.

Good to illustrate, poor in functionality.
Educationally valuable only half because the child / young person is greatly disillusioned at the end by the poor functionality and loses the funny thing.
"Wind power is going've no ..."

You have to lend a hand and using soldering irons and home banking optimize the part and get run as resourceful craftsman home already. This then is the greatest educational benefit.
