We can extract in an external circuit and generate current and voltage from the material. now, in terms of the limitations, if we look at what's the optimum efficiency a single solar absorbent material could be, like silicon, they top out at about 25%. that's really the practical limit for an actual solar panel with today's silicon technology. so, i'm hearing 6%, 7%, 8% from danielle. i'm hearing 20% from you. we're not quite at that 85%. and all of this energy we generate needs storing, doesn't it? so, kristian, i know that you're a man of the fjords and boats and ships have been a constant t...
