“Pump and Surf” encourages internet users to find out how much energy is spent when they are surfing the internet. Before being able to view a website, internet users are asked to make a physical effort similar to the energy required to convey the data that will enable the site to be displayed. Through interactive experiences and graphic visualisations, “Pump and Surf” leads users to take the measure of the quantity of energy involved in the exchange of information, to the point of feeling them physically.
