Pollution-Eating Concrete Invention.
An article on an interesting invention was published today at CNNTech, found here. The article discusses the use of titanium oxide coatings on concrete to remove nitrogen oxides from the environment. Also, the article briefly highlights the “race” to explore new technologies for mitigating pollution.
We recommend the article as a quick and interesting read, if you have a few minutes to spare.
Hopefully, the USPTO’s new fast-track processing for “green” patents will encourage more such inventions. It’s always heartening when patent law and the public interest intersect, and we need environmentally-friendly products now more than ever.
