or just those glaring large slabs isn't quite the look we're after. so i've been to the homes of two british start—ups. who want you to look again. this is the solivas arc. it's curves are wrapped in an organic solar film which doesn't contain any toxic substances nor rare earth materials that could require mining. and so it has a much smaller carbon footprint than traditional panels. and that's not all. now the arc is designed to capture sunlight throughout more of the day. and that is partly because it's got five surfaces on which to harvest energy. and this curved design means that usually it has a sweet spot which is very useful at the start and end of the day in particular. i think it looks quite futuristic. and if solar sculptures like this were to catch on, i can see them being seen as a sort of carbon neutral status
