Urban Rooftop Farms Produce Edible, Nutritious Algae [Pics]
Unused space on a Bangkok skyscraper is transformed into a production site for this super food.
Urban farming and algae are both initiatives that have huge promise for making the most of land and sea where there is very little left to spare. Instead of trying to use one approach over another, sustainable food production company Energaia decided to combine them both on the rooftop of a Bangkok skyscraper.
The roof of a skyscraper serves as an excellent venue for harvesting the edible algae spirulina because of the high temperatures and constant sunlight, both of which help to optimize growing time.
