Getting on with the idea

Lucas was making prototypes based on the idea he had developed earlier. He had decided to make few variations just to see how they worked and what would be the best material for the final version. He was also writing down all costs and the availability of materials for each prototype. Sustainable consumtion and material effenciency were important issues for Lucas, and he wanted to follow these when ever he could.

Good imagination is essential when inventing something new. Courage to try something nobody else has done before is another important factor. This doesn't mean foolhardiness, mind, the realism is good to keep in mind. Lucas knew that these were qualities he needed to keep developing at all times because if you don't believe in yourself why should the others do.
