As I said in so many words in the article, I don't know if their claims are on the up-and-up. That's why I didn't encourage anyone to invest in it.
BUT neither did I automatically dismiss their claims. IF - and I mean IF - their self-charging batteries are not much more expensive than NON-self-charging lithium-ion batteries are today, then it will be a true game-changer.
The market will decide, and we will see. Unless, of course, somebody from one of the industries such a technology would render obsolete decides to buy them out and bury the tech.
