In addition to the mentions above the game played in the movie is called Roller ball and has no basis in Hockey. If you watch they are playing with lacrosse sticks playing a game that more resembles that sport merely put on skates and the goal put in the middle of the skate rink rather than on either end of the field.

In a future in which most water has disappeared from the Earth, we find a group of children, mostly teenagers, who are living at an orphanage, run by the despotic rulers of the new Earth. The group in question plays a hockey based game on roller skates and is quite good. It has given them a unity that transcends the attempts to bring them to heel by the government. Finding an orb of special power, they find it has unusual effects on them. They escape from the orphanage (on skates) and try to cross the wasteland looking for a place they can live free as the stormtroopers search for them and the orb. Written by John Vogel

In the future, a nuclear war has left the Earth as a desert wasteland where the ocean has dried up leaving the Earth as a vast desert landscape. Most of the water supplies are controlled by the elite corporation E-Protecorate, where the E-Protectcorate takes children away from their families and are forced to live in a orphanage, where they are to be trained as E-Police, the E-Protectcorate's security army led by the cruel commanding officer Grock. After playing a game of Skateball (Hockey on Rollerskates) against their rival team 'The Scorpions'. Daniel, the youngest member of the Solarbabies discovers a glowing orb from another galaxy called Bodahi in a mineshaft and Bodahi heals Daniel's deafness. The Solarbabies learn Bodahi has amazing powers. And the discovery of Bodahi convinces the Solarbabies to escape from the Orphange and fight back against the E-Protectcorate. Pursued by Grock, who is after Bodahi, The Solarbabies travel across the desert wasteland, where Bodhai is the key in their quest to defeat the E-Protectcorate and liberate the world from it's control.
