Study Notes
Solar Absorber Design
- Researchers replaced graphite with a metal and ceramic composite material in their current experiment.
- Perforations in the two layers of the solar absorber allow for efficient water boiling.
Initial Design Challenges
- The initial solar absorber design faced a problem: it couldn't boil water directly.
- Additional devices were required to boil water using the initial solar absorber.
Metal and Ceramic Composite Material
- The metal and ceramic composite material's high thermal conductivity helps in efficient solar absorption.
