What does it mean?

sunthalpy is an abbreviation of the English sun and enthalpy. Enthalpy, enthalpy in Spanish, we can say in a simplified way that it is a form of energy. For us, sunthalpy is the realization of a utopian world in which we can enjoy technological development to the fullest but in total harmony with the environment, so that our environmental impact is zero. Satisfy all our energy needs using the sun as the only resource, the origin of all clean energies.
