Researchers at Washington State University are working on hydrogen-storage solutions involving nanosprings.
Professor Grant Norton, along with Idaho physics professor David McIlroy, created nanosprings in 2001. Made of silicon oxide, these springs are 10,000 times narrower than the human hair and will hold hydrogen atoms. The idea is to replace the tank that holds hydrogen under pressure with "trillions and trillions" of nanosprings.
Another WSU professor, Matt McCluskey, is working on a similar plan but with a different nanomaterial that actually stores the hydrogen inside the metal. A curvy shape would not be needed.
The researchers admit their project is "highly speculative" but certainly worth the effort.
