Jak and Daxter: The Precursor Legacy/Sandover Village

After you arrive back at Samos's hut Kira tells you that you need to collect 20 power cells to power the heat shield on your zoomer to get across Fire Canyon. There are six power cells in the village and 50 precursor orbs.

Bring 90 Orbs to the Mayor
The Mayor is located in the windmill. The first time you see him he will tell you the blue eco beam coming from the forbidden jungle which powers the village has been cut off and will give you a power cell if you restore it. After he gets done tell you that he tells you to give him 90 precursor orbs for his reelection campaign and he'll give you another power cell. If you have enough precursor orbs, give them to him for the power cell. If you don't, look around village for some more orbs.
