Well built, but even long-term motivation

The COSMOS product on wind-energy is one of many educated groups packets which make KOSMOS for me and my son generally interesting. The kits are generally very well constructed and guidance designed to a child-oriented knowledge transfer is achieved.

This also applies to this package, which essentially comprises a pinwheel ready to be set up. The small generator and gearbox is encapsulated and to build in one piece. All in all, had my son (10) the correctly assembled in less than 1 hour. A first test with the finger was already guessed that not a gentle breeze would be enough to test the wind turbine. After two days we had enough wind - but the base plate including building efforts wind load has not grown.

So in order to realize the function advertised charging a battery, care must be the one for additional fastening and beyond find a weatherproof location with wind. Both are rather difficult and so it remains in fact in a small red LED which testifies generated Kleintsenergiemengen.

The replica of something brought about by the hair pulled further models could not convince. At the generator might have been to emphasize the theme of gear more. The enclosed gears are only decoration.

That left after a first build and test the long-term game fun fast on the track - and therein lies the obvious drawback of this otherwise compiled with devotion package.

Overall, this product is thus not to the lofty yardstick of electrical and electronic series of the same home approach, which I think is a pity.
