• Using light-activated nanoparticles, light is captured and turned into plasmons, which are "waves of electrons" that can glide across the metal surface of nanoparticles. This means researchers can essentially harness highly excited electrons, known as "hot electrons."
  • Using this system, the team was able to take the energy from hot electrons to split water into oxygen and hydrogen -- which is exactly how to turn water into energy for fuel cells or propellant for spaceflight.
  • The process is still in the early stages but could eventually lead to solar energy becoming much more efficient at converting solar to electric, which would mean cheaper solar energy.
