One thought on “Technology to Make Clean Energy From Coal Is Stumbling in Practice”
My father, a career engineer, told me that all engineering projects underestimate costs by a factor of 2, and overestimate benefits by a factor of 2. This rule of 2’s becomes a rule of 3’s, 4’s, or even more when the project is a prototype using novel technology.
