Thames & Kosmos Wind Power V4.0 STEM Experiment Kit | Build a 3ft Wind Turbine to Generate Electricity | Learn About Renewable Energy & Power a Small Model Car | Weatherproof for Outdoor Use

I am 20 years older than 18. I always enjoy tinkering. I am interested in wind generated power so I got this given I felt it was reasonably affordable. Very easy and forgiving to setup. The piece that houses the battery and motor compartments plug and plays between the trmie one and the car you can construct. Additionally, you will need rechargeable batteries for they are not included. Enjoy!

got for my boyfriend for a fathers day gift, thought it was absolutely cute and the fact that it charges a battery was even better. (hes an electrical engineer who specializes in wind turbines) he loved it! only downside was the directions seemed to be written backwards? or it wasnt wired correctly lol but he still loves it anyway

But probably generates no energy. If you got like a bunch of these and used the batteries to charge up your phone. Maybe. I held it out during a hurricane and I was afraid it was about to slice my head off. Was spinning ridiculously fast and didn’t fly off for the 5 seconds I stupidly held it there Good for learning and just as an emergency although you’d have to go with the method I mentioned. Not 5 stars because I feel the base is not securely attached to the stick at all. Better mechanism

Fun little windmill that comes with great detail and instructions on how wind energy works. Need a pretty strong wind to actually make it work and will only charge a single battery. Great way to show others interested in wind energy. Highly recommended

Assemble is easy for an 11 years' old. Information about wind and wind energy included in the manual / booklet is great. But that's all about it. Problems: 1) As pointed out by one other reviewer, when in generating mode ("arrows on the nose cone point to 3"), the turbine blades turns clockwise, not counter-clockwise said on page 9 of the manual. 2) Outdoor use to turn the turbine is practically not possible. In an indoor experiment with a powerful fan turned on to generate the highest wind, it can turn the turbine. We do not see charging indication lights on. We'll update this review if we ever be able to make charge of a battery. At best, this is an educational tool for illustration purpose. Product needs to be improved. Also, it seems that for those customers who got a free product to test, their reviews are in general on the generous side. Update on 01/22/2021: The red charging light is on after about an hour. We then continuously charge the battery for about 3 hours. The battery works to turn the windmill to a fan (spinning very slowly, though). My son turn the turbine into a car; however the gears are poorly constructed that they cannot drive the car at all. We put the charged battery into a Thomas train and the train drives nice and fast. As such, I change the overall rating from 2 to 3.

Ok

Perfect for a science fair project

Another wonderful product from Thames and Kosmos! When my young son repeatedly asked for a windmill to create electricity I did a search and ultimately decided on this one because of the extra depth of possibilities it contained. The windmill can charge a AA battery to be used in something else or you can turn the base into a car. Perfect for my son to see the applications of his wind energy. It came with a great book that goes into detail about the science behind wind energy and real applications of it. This is something we will have for a long time and will continue to learn from as he gets older. Product will last for years to come.

Turbine would not turn in wind. Some would think this a basic requirement of a wind turbine.

Es un juguete

Learning aid

Easy to build, good quality. My son really enjoyed this.

Mein Sohn hat bis heute viel Spaß daran Und nimm die Umwelt besser wahr.
