Urban Algae Canopy will generate a 4-hectare forest's worth of oxygen

London's ecoLogicStudio has demonstrated a full-scale prototype of its urban algae canopy at the "Feeding the Planet" expo in Milan. This "bio-digital" structure sees fluid filled with microalgae organisms pumped around an otherwise transparent shelter to produce dynamic shade, energy in the form of biomass, and an impressive amount of oxygen, while responding to the presence of visitors to produce interesting visual effects.

NASA-funded research seeks to produce breathable oxygen on Mars

Establishing and maintaining a permanent human presence on Mars promises to be one of the most technologically challenging ventures ever undertaken by our species. A key aspect of the endeavor is to create an environment in which human beings can survive and flourish – this requires a ready supply of oxygen. NASA is working with Indiana-based company Techshot Inc. in order to develop a solution with the potential to produce an abundant source of oxygen with minimal assistance from Earth.

Algae could both provide biofuel and clean up wastewater

Algae may indeed be a potential source of biofuel, but it can also find use in things like nutritional supplements and cosmetics. When it's grown commercially, its growth is usually aided with chemical fertilizers. The cost of those chemicals cuts into the profits, however, plus the fertilizers are also needed for more traditional crops. That's why scientists from Houston's Rice University are looking into growing algae in municipal wastewater – the water would already contain its own free fertilizer, plus the algae would help clean it up.

Autonomous underwater vehicle looks for algae on underside of ice

Early every spring in Antarctica, mats of algae form on the underside of the sea ice. These mats – along with bacteria that live in them – serve as a food source for zooplankton, essentially kickstarting the food chain for the year. Given that the ice algae plays such an important ecological role, scientists from Denmark's Aarhus University have set out to better understand its distribution. In order to do so, they're using a high-tech underwater drone. Read More

Researcher looks into wastewater zooplankton as biofuel feedstock

With dwindling non-renewable fuel sources creating an enormous energy challenge, the search is on to develop sustainable, renewable types of energy such as solar, wind and biofuel. One of the recent developments in this field comes from New York's Clarkson University, where new findings suggest that small organisms found in wastewater treatment lagoons could be used as biofuel feedstock.

Algae to crude oil: Million-year natural process takes minutes in the lab

Engineers at the US Department of Energy’s Pacific Northwest National Laboratory (PNNL) have created a continuous process that produces useful crude oil minutes after harvested algae is introduced. This new process does not require drying out the algae, which grows in water, saving time and energy that would be otherwise wasted. The final product can be refined into aviation fuel, diesel, or gasoline. Read More

Portable device detects toxic blue-green algae in water

Cyanobacteria, more commonly known as blue-green algae, can potentially be quite nasty. Some types of the bacteria produce toxins, which can poison humans or other animals that ingest water in which they’re present. Now, however, scientists are developing a portable sensor that will instantly alert users to the presence of the microbes in water samples. Read More

Austrian algae biofuel-production technology to debut in Brazil

The state of Pernambuco in Brazil’s northeast is going to become home to the country’s first algal biomass plant, thanks to an agreement between See Algae Technology (SAT), an Austrian developer of equipment for the commercial production of algae, and JB, one of Brazil’s leading ethanol producers. The plant will produce algal biomass from natural and genetically modified strains of algae. Read More
