What is it about?
Similar to solar energy used in solar cells, phonons can be harvested using its spectral character.

Why is it important?
We look for new semiconductors which can convert spectral phonon to electricity. We also recycle spectral phonons generated due to resistive heating or produced due to inefficiency in energy conversion.
Perspectives
Viewing heat in solids as spectral phonons and developing devices which can harvest them opens new understanding of thermal energy and its conversion.
