Natural Fuse
"Natural Fuse" harnesses the carbon-sinking capabilities of plants to create a city-wide network of devices that act both as electricity outlets and as a shared resource that offsets CO2 generated in the production of that electricity.
The project was originally commissioned by the Architectural League of New York and Natural Fuse units are available for rent from the Toward the Sentient City exhibition, at the Urban Center in New York City until November 7, 2009.
Natural Fuses allow only a limited amount of energy to be expended; that amount is limited by the amount of CO2 that can be absorbed by the plants that are growing in the system - natural "circuit breakers". By networking them together, the plants are able to share their capacity and take advantage of carbon-sinking-surplus in the system since not all Natural Fuses will be in use at any one time.
If people cooperate on energy expenditure then the plants thrive (and everyone may use more energy); but if they don't then the network starts to kill plants, thus diminishing the network's electricity capacity.
During research and development we encountered several issues that have affected the design process. These highlight the kinds of challenge faced by "carbon sinking" initiatives in general.
For example, the amount of CO2 that a single houseplant can sink is much smaller than expected. What would you do? Use less energy? Or supersize the fuse? You might need 420 plants to offset your 50W lightbulb!
Second, when a plant dies any carbon sequestered during the growth period is, in the absence of continued sequestration (e.g. by sealing it deep within the earth), soon released back into the atmosphere. A zero-sum situation depends entirely on where the arbitrary boundaries of the system are drawn. What would you do with your plant? Eat it? Bury it? Weave it?
On the unit, there is power-activation switch, which the owners can adjust depending on how much they want to use the energy. There are 3 modes, OFF, SELFLESS and SELFISH.
In "OFF" mode, the system uses minimal energy, turns itself on once every hour. No energy flows to the appliance connected to the unit. As a result, the overall CO2 absorbed in the whole system gradually increases, and the plants in this unit are cared for by the system.
In "SELFLESS" mode, the unit gives power to appliance at a rate that ensures CO2 production and capturing in the entire Natural Fuse system remain in equilibrium. As a result, owner might be able to turn on the lamp for 10 mins a day, depending on status of the whole system and consumption rate of the appliance.
In "SELFISH" mode, the unit gives as much power to appliance as it needsAs a result, the owner can use the appliance as normal but it might cause the whole CO2 absorbed in the system to decrease or even lead to total systematic breakdown. CAUTION: IF SYSTEMATIC BREAKDOWN OCCURS, THE SYSTEM MAY KILL 1 RANDOM UNIT'S PLANTS, AND IT PROBABLY WON'T BE YOUR OWN!
Original project description preserved below:
Commissioned by the Architectural League & Situated Technologies: Toward the Sentient City, Natural Fuse will be open to the public in Autumn 2009. The purpose is to create a collective "carbon sink", that offsets the amount of energy consumed by the plant owners - a natural "circuit breaker". If people cooperate on their energy expenditure then the plants thrive (and they can all use more energy); but if they don't then the network starts to kill plants, thus diminishing the network's energy capacity.
Every seemingly helpful device that a human being uses has its own carbon "footprint" which, in excess, can harm other living beings. Natural Fuse is a micro scale CO2 monitoring & overload protection framework that works locally and globally, harnessing the carbon-sinking capabilities of plants.
Natural Fuse allow only a limited amount of energy to be expended in the system; that amount is balanced by the amount of CO2 that can be absorbed by the plants that are growing in the system.
In the same way that circuit-breakers are useful for preventing excessive current use, so too can the Natural Fuse plants break the CO2 footprint "circuit". What would you do? Use less energy? Or supersize the fuse?
Accompanying the units developed for the project will be a website that enables people and plants to connect (a sort of "social-networking site" for plants); a manual for building your own Natural Fuses based on the Arduino Ethernet platform; and a "shop" that will form part of the exhibition.
Part of this project's approach is to raise awareness of energy expenditure and encourage people to collaborate to share their energy use and nurture their plants.
