The ice cream factory (2011)

"There is too much carbon in the air and Captain T has a temperature. The Carbon Busters have to help him. Wanda, Chu, Peter and Riva, travel on their Pulitos (clean energy scooters) to a hot place that is completely without ice cream. The town is in a slump. The smoke from the old generators at the ice cream factory is turning the air bad and making children cough. The factory must close today! With the help of Sweetie, the owner s daughter, and a clever idea, Chu, who is today's leader, must find the confidence to persuade the grownups on the factory board to try a new energy solution that just might save the day!"--Publisher's description.
