The Swedish company ClimateWell manufactures air-conditioning units that run on solar cells using a unique, patented technique.
The technique involves storing energy from solar cells in a saline battery, which can then both heat and cool down the immediate surroundings. This works best in hot countries where there is a lot of sun and considerable need for air conditioning.
In his opening speech, The King referred to ClimateWell as a typical Swedish example of how inventions can be used to solve key global challenges.
