People who work in power plants that produce electricity from fossil fuels could lose their jobs.
Piezoelectricity may not be sufficient to create 100% of the energy needed for the school.
The materials used to build a piezoelectric floor, wall panels, other energy-capturing materials, and antibacterial materials might be very expensive.
Cork used on the floor can actually absorb sound.
At night and over the weekend or other times when kids are not present, the school might need a backup source for power.
