CO2 rich air could be captured and piped to algae ponds alongside the freeway
Mans Tham's "Solar Serpents in Paradise" idea would see city freeways covered in solar panels
The Solar Serpent would also provide shade to commuters
With solar power plants requiring large areas which aren't usually available in or close to urban areas, Sweden-based architect Mans Tham proposes cities like Los Angeles take a different road – covering the city’s freeways in solar panels. His "Solar Serpents in Paradise" idea would see 24km (15 miles) of LA's Santa Monica Freeway covered in solar panels – with an average width of 40m (131 ft), that adds up to an area of 960,000 m2 (10,333,354 Sq Ft), enough space for 600,000 domestic panels, which could generate 150 GWh per year. That's more than enough to provide electricity to all the households of Venice, California.
