Floating over top of the valley and highways will be the supposedly self-sustaining disco ball-like sphere. The press release says that 30 percent of its surface will be covered in solar panels, which will power the sphere, allowing it to hover while also supplying 235 houses with power. The mirrored bottom is meant to be a work of art that gives drivers a 180 degree view of the surrounding area. There is no information available about the size of the sphere or the technology that will allow it to float.
While the valley design makes perfect sense to us — we like the idea of re-using the earth dug up during construction to create a more pedestrian and bike-friendly junction — we’re a little bit lost on the purpose of the floating sphere. Perhaps its just the lack of details, but it seems like it is an unnecessary use of materials tacked on to a perfectly smart design.
