      Once I was reading an article about how a specific type of battery; it later said that it was not rechargeable. And I asked the question, “why? It doesn’t make sense!”.
      So I set about understanding that statement; I worked out the “WHY” of the battery not being rechargeable. It turned out to be a very subtle thing to do with something called “enthalpy”.

      Then I had a thought, I wondered “what if you did it a different way instead, would that make it rechargeable?”. When I built it and tested it, I found it was more than just rechargeable, it turned out to be one of the best ways to make a battery ever discovered; it was also the cheapest (20 times cheaper than current lithium batteries).

      So I ended up inventing something just because I asked a simple question; “why?”
