Our Name and Logo

REhnu (pronounced “renew”) derives its name from the formula

E=hν    or    E=hnu

which relates the energy E of a photon to the photon’s frequency, given by the Greek letter ν, or “nu”, and Planck’s constant h. The R preceding E in our name signifies the REnewable nature of energy derived from light.


Our company logo is inspired by Richard Feynman’s iconic diagram of a photon (wavy line) transferring its energy to an electron.
