Researchers at the Nelson Mandela Metropolitan University (NMMU) in South Africa have developed a new fuel, known as Coalgae. Made from a combination of algae and coal dust, the latter of which is a waste product, the fuel could have a significant positive impact on the environment.
Researchers from Concordia University in Montreal are looking to tap into what may be the most plentiful yet overlooked source of power in the world. The group has invented a power cell that harnesses the electricity created during the natural processes of photosynthesis and respiration in blue-green algae.
Algae is proving to be pretty darn useful – in recent years, it’s been used to produce oxygen, purify wastewater, provide light and serve as a source of biofuel. Now, bioplastics firm Algix and clean tech company Effekt are making flexible foam out of the stuff, too.
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.
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
