i remember reading some place new tech on solar panels ones that you can even in the future be able to just paint them on, its a new tech pretty much cylindrical style vs the linear type to day, the light goes inside the center and goes through the walls that way getting far more light then going through the other layer, at least thats how I understood it. I forget the efficiency or hope for, they said it will still be like something 5 years+ until its commercial :/
honestly patents should be like, you make prototype if not, you cant get the patent for your imaginary abstract ideas, that are just stooping the real production of the tech when it arrives, i think the whole idea was good with patents but is completely abused and misused today
