what you see here is a fully self powered, sustainable powered headphone. it has a leather structure to it. and it will actually absorb any kind of light and convert that light into electric energy and charge the battery. if you go to the office, the gym, whatever you do, they will always charge during the day. but the luxury of not needing conventional charging will add a chunky $50 to devices, several of which have already been created. this is a self powered speaker. if you look on the back it is a solar cell. a smart helmet can sense when it is being worn in the dark and light up automatically. here are the charging panels. one, two, three. it s actually one cell underneath. they really blend in. and this bag doubles up as a power bank. this is a pretty big surface and you can place this in the sun so it will charge a lot. charging from ambient light does have its limitations, though. how about a laptop, how far away are you from being able
electricity that s being used anyway? we are recycling light. the extra efficiency means that the silver strips that usually run through solar panels are no longer needed, freeing up new design ideas. these cells have been shaped to fit a headphone band and this robot is responsible for squirting electrolytes on them to allow conduction. it looks like it s going to drip bits in between. but it s actually doing very precisely? it s more efficient and predictable and for sure doesn t make any mistakes. the final step is lamination to give the cells custom textures. and into the press it goes. and here s the finished product. giovanni, tell me about the prototypes you ve got here? what you see here is a fully self powered, sustainable powered headphone. it has a leather structure to it. and it will actually absorb any kind of light and convert that light into electric energy and charge the battery. if you go to the gym, whatever you do, they will always charge during the day. but the luxu
