After the lecture, the afternoon continues with a panel conversation with Petra Wadström, Nina Wormbs, Professor in history of technology at KTH, Anders Nordström, former Ambassador for Global Health and advisor to WHO will have a conversation about the importance of innovations that have the power to build resilience for both people and the planet. The panel will be moderated by the science journalist and writer Eva Krutmeijer.

The climate crisis hits the most vulnerable populations in multiple ways. How can we better prepare and why is a just transition so important when it comes to global climate action? These are some of the questions that will be adressed to the panelists.

Exhibition opens in the KTH library

Petra Wadström exhibits her innovation Solvatten in KTHB during the period 28/11-7/12. The exhibition opens on Tuesday 28 November at 15.30.

How the Solvatten technology works

  •  The two-part black container is filled with water.
  • The Solvatten purifier uses solar heating and UV radiation to purify the water effectively: the sun’s ultraviolet UVB rays are released through UV-transparent surfaces, and the water is heated against the black inside of the container. The resulting synergies render pathogenic microorganisms harmless.
  • The Solvatten container also has a filter that removes water organisms, making the water less turbid.
  • Once the process is finished and the water is clean, according to WHO guidelines for clean water, an indicator shows a green smiley face.
  • It takes two to five hours to clean 10 litres of water of harmful microorganisms, which can otherwise cause dysentery, typhoid fever and cholera.
