On 12th March, our penultimate day in Sweden, we went to KHT : Kungliga Tekniska Högskolan in Stockholm. After having seen the building from the outside and the square in the centre of the complex, the student who was our guide took us inside
We went into a room where a researcher was waiting for us to talk about renewable energies and electric cells in particular. These are electrical energy containers and can be useful in many fields. She showed us a device made of different parts which convert solar energy into electricity.
The sun was represented by a little lamp, whose rays are captured by a solar panel. This allows electricity to separate water into hydrogen and oxygen. Then the two gases are sent inside a condenser where energy and water are created, with a bit of dispersion; the energy is used to make a fan work, while the water can be recycled.
Afterwards we visited another room to listen to the guide and another scientist explaining how to recycle waste water, since most people only think of throwing it away.
It was very interesting to learn more about such relevant themes and so cool to see how many guys from different countries are working together to find new solutions.
