Patent protection is a technical means. Ideas alone cannot be patented. For example, what you mentioned above is the transformation of old things. Then you need to write down how to transform them and what will happen after the transformation. What technical effects you want should be clear enough to the point where a person skilled in the field can achieve it after reading your explanation. Of course, if you apply for a patent, then even if others know how to implement it, they still need your consent before they can implement it.
