I liked the post. The fact that you were pissed bored writing it made it sound fun. Now in terms of information, well perhaps for those from science it doesn't give much. But for an average non science person it could be information he can read and then boast about on whatapp. Well yes they can find this information on google too, but why in the world will I be looking in Google for potato to make battery. It is more like one of those catchy click bait post but with nice revision on how stuff works. So 20/20 won't be bad for this IMHO.
