Without scientific understanding, the only way to make progress is by trial and error. That is very slow and expensive, and there is no telling whether it will work or not.
Well, Alan Smith and Russ George have figured out how to make the process work. And, from what I gather it's pretty cheap too. So, let's hope they disclose their recipe for others to replicate their work.
The data published here is intriguing but it will not convince any scientists. If this is all they have published, they have not yet begun trying to convince scientists.
Perhaps they've convinced themselves, given that they are scientists also and/or engineers. They've already seen the future that will arise out of their studies, could be a profound experience.
