This small turbine is portable and can still do the same thing regular sized turbines can do. This turbine has two sizes which are small and large. The small one is used for charging things like phones and the larger one is used for things like charging electric cars. It also comes with an app so you can monitor the energy level. You can also turn it on and off from the app.
This relates to engineering because somebody had to figure out how to create a mini turbine using smaller materials but still have it work just as good. They had to put in enough mechanical tools so it could do things like charge a phone and a car.
