So there, Marius, I'm really intrigued! A concrete steam car, I admit that I would never think! Concrete, as you say, it's very solid, but also very heavy, but a concrete that floats, it's a self really a very ingenious idea! We really need inventions to help us spend energy if we want to take care of our planet. And then a car that goes in the water and on the ground too, what is practical! There are some amphibian vehicles, but not enough! What I particularly appreciate here is that you did a lot of calculation to see how it works and how long. This is exactly the kind of approach that 'big' inventors make when they imagine their machines. So congratulations, and zou, I go see your next invention!
