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.
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.
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
