Pumping out Oxygen
like nobody’s business.


With a name taken from the Tree of Life in Norse Mythology, Yggdrasil is a concept for an air purification system that uses a biomimetic process known as Artificial Photosynthesis (APS) to reduce the density of CO2 (and other impurities) in the air of urban environments. Having been inspired by organic systems, but a machine by nature, the device is able to operate without time being defining factor.


To operate successfully, the device needs three key ingredients: Water, Light and Carbon Dioxide - the latter two of which are easily and readily available. The water can be supplied to the device directly through a branch from a main water system.

With the light hitting the device's surface and water being fed into the system, the air that is being pulled into the device has its impurities extracted, with the newly produced oxygen being released through the venting network. The carbohydrate by-product (i.e. glucose) is used to fuel the device's bio-battery where it acts as a dormant power source, only to be activated in an emergency low-power situation.


The product has been designed as a modular system so that units can be combined (or separated) depending on the volume of purification required (as well as the available surface area). The devices are recommended for 'above ground' installation (i.e. on top of buildings, flat roofs, etc.) so they have unrestricted open-access without disrupting the limited ground-level space. This also acts as a deterrent and preemptive measure against potential tampering and vandalism, as well as reducing the risk of accidental damage.

In regards to monitoring the operational status and general diagnostics of the system, the data can be streamed wirelessly to the appropriate monitoring directory. A repository could be created to store the collected performance data so that members of the public could, if they wish, review the levels of pollution in their respective areas.


Urban pollution has always been a cause for concern but in recent years the levels have risen beyond critically dangerous and don't seem to show any signs of stopping. This project aimed to take the organic air purification processes carried out by flora and replicate it synthetically, adapting to urban environments where space is limited. The beauty of the artificial process is that it removes the time needed to 'grow' plants as well as other factors, such as eliminating disease and decay, which also associated with living objects.
