Freeways are traditionally not very eco friendly and tend to produce nothing more than carbon dioxide. The city of Los Angeles got around 800 km of freeways and Swedish architect Måns Tham has come up with an idea to turn the freeways into green, energy producing networks than run throughout out the city by covering the roads with solar panels. If that isn’t enough Måns Tham suggests that algae ponds should be placed along the roads. Algae that cleans the car exhausts from carbon dioxide. The algae can then be harvested and turned into bio fuel. Information on how much energy the freeways could be able to produced can be found after the jump or at Måns Tham website.
Santa Monica Freeway (downtown to the beach):
24 km avarage 40 m width = 960.000 m2= 600.000 domestic panels (1,6 m2)
Peak effect for Santa Monica Freeway 115 MW = 150 GWh per year
115 GWh is enough electricity for all households of Venice, CA
