[@LeeRoy] Aerogel is just an improved form of gel. The idea of a gel was not original when it was invented. Colloids were a well known form of matter, and the idea of suspending a solid in a gas was already well established with aerosols. Even its function as an insulator is not novel. It would be hard to think of a less original idea. The Telegraph is not original at all. It's just glorified smokes signals. You could go on, and so could I. It's actually quite fun, as I didn't even know aerogel was a thing until I looked it up to see what idea it was based on.
