I had an internship at a place that did research bringing things like this to market. The problem isn't just marketability. The problem is being able to reproduce something. There is a big gap between what one very smart person can do in their lab, and what a factory can produce. A technique that can't be mass produced can't help the masses. Profit is obviously a motive, and that's an entirely different discussion. That being said, a lot of really interesting research is lost because it can't be made into a product, and it's a big problem. Even if a charity wanted to give this away for free, it's not possible without being able to make this into a mass marketable product.
