Poland's town of Lidzbark Warminski is testing a self-sufficient, solar-powered bike lane that not only looks good but also makes cyclists safer.
It's like a big aqua Roomba that cleans up waste and pollution while logging real-time water quality data.
Comprised of shipping containers that could be organized in different configurations, each unit boasts enough space to house 12 students at the same time.
It also uses 97% less water than outdoor farming, with the highly controlled environment helping to avoid pesticides, GMOs and herbicides.
They could also be used to make bridges and sidewalks, all of which will be highly insulated, much stronger, and a lot cheaper to build.
