no, no you keep rocking the blue and i will keep rocking the grey in more ways than one. meanwhile, here s a way that you can make your gadgets greener by using sustainable energy, something this solar cell factory in sweden is taking to the next level. this machine is printing custom nano ink onto solar panels, and they don t even need the sun to charge. we have developed our own nano inks, and in this machine we will print that ink on the proprietary substrate. how is the end result and the usage of it different to other solar cells? it actually harvests all kinds of light. it s sort of like artificial photosynthesis so we work under any light conditions, led, normal light bulbs, even in the shade. any kind of light. you re sort of using electricity but i guess its electricity that s being used anyway? we re recycling light.
