This year's project is called Kinetic Roads Electrically Sourced Highways, or K.R.E.S.H. for short. It uses the power of piezoelectricity(pronounced "pee ay zo electricity) to energize street lights, stop lights, and even car charging stations!

Piezoelectricity is caused by piezoelectric materials, such as quartz, PZT, and even bone, being squeezed or heated up, causing the molecules to line up a certain way. The materials usually generate high AC(alternating current) voltage and a low amperage. The voltage is how much electricity there is, while the amperage is how fast it flows. The difference between AC and DC(direct current) is that AC, as the name suggests, alternates between positive and negative, while DC is essentially two straight parallel positive and negative lines.
