Gravity Powered Fan Car

Prathik Adi asked "Can you make a gravity powered fan car" so I modified my gravity powered boat to see if it would move using a fan.

Putting some sort of flywheel on the shaft to keep it spinning would prolong the 'thrust' time, you could experiment with the gravity weight dropping off the car entirely so it is left behind and all the energy will have been transferred to the flywheel. Feel free to try this for yourself, I am not going to spend any more time on it.

Generally my projects are for my grandchildren to enjoy. OK, I enjoy them too. If anybody else likes them, that is a bonus. I like to keep my work as simple and basic as possible so that it can be copied easily and improved by anybody who wants to try themselves. I recycle or repurpose items rather than buy new and when I do buy I like to keep it cheap.
