The Finland pavilion at Expo 2020 Dubai is keeping up with its motto of, “The Finnish exhibition shares an in-depth story of #Finland, providing visitors with experiences to showcase the foundations of Finnish happiness: continuous development and #innovation, #sustainable & environmentally-friendly solutions & extensive international cooperation.”
A new kind of coffee machine is available here. This coffee machine is powered by the air we breathe! This process is a cheaper and sustainable option to otherwise using electricity. Here is the entire process:
“Electricity to power the espresso machine is extracted from the air in the pavilion, and the espresso machine is a great way to demonstrate this,” said Mario, a volunteer at the pavilion. The Finns love drinking coffee, and we drink more coffee per head than any other country – about 12 kilograms per person every year. The machine is powered by a generator that extracts air from the pavilion to utilise carbon dioxide. It separates the CO2 from all other gases in the air. At the same time an electrolysis process separates hydrogen from the oxygen in the water. We then use the hydrogen combined with the CO2 taken from the atmosphere inside the pavilion to create methane. The methane is then used as a power source for the coffee machine. It burns inside the machine to create electricity and a by-product of water that is also reused.”
