The Cloudstar is a balloon that destroys bacteria and viruses with the use of modified light. The Cloudstar does not harm human skin in the process.

The Cloudstar also detects heat differences inside of individuals.

People who seem to be sick are identified in larger crowds due to heat differences in their body. This process helps to reduce the spread of Corona.

The Cloudstar is used by the Cloud Nation during times of Corona to identify heat-differences inside of individuals, and to clean surfaces around the world from bacteria and viruses.
