"In Gensler's proposed solution, the greenhouse above produces food while the hydrogen generator below creates electricity to split water molecules into pure Hydrogen and Oxygen. This new fuel cell energy will be used to power nearby Chicago Public Schools, in turn helping the CPS reverse its budget shortfall from last year which resulted in teacher layoffs to offset rising utility bills. Simply put, Hydrogen = Teachers. The excess Hydrogen will be sold to alternative fuel vehicles at depots throughout the line."
