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.

Bring 90 Orbs to your Uncle
Your uncle is located in his house by the windmill. When you see him talk to him he will ask you for 90 precursor orbs so he go one a voyage and in return your uncle will give you a power cell. If you have the orbs give them to him and get the power cell. If you don't have enough then go find more orbs.

Herd the Yakows into Their Pen
Talk to Farmer Zeb who is located on the beach outside his house near the entrance of the Forbidden Jungle. Farmer Zeb will be sleeping outside his house, go wake him up and he will tell you that his yakows have escaped and if you herd them back into their pen he will give you a power cell. Farmer Zeb has 5 yakows located around the beach area. If you smack one they will start walking stay behind them or else they will return back to there starting positions. When you are herding the yakows if you go onto the left side of the yakow they go right, and if your on the right side of them they go left. When you finish herding all five back into their pen go talk to Farmer Zeb and he will give you the power cell.

Bring 240 Orbs for Two Power Cell to the Sandover Village Oracle
The Oracle in Sandover Village is located near the entrance of the Forbidden Jungle, on top of a cliff, over by the farmer's hut. To get to the Oracle, you'll need to climb up the rocks near the water on the beach. Jump across the rock platforms to get to the cliff where the oracle is located. The Oracle has two power cells, one in each eye. Talk to the Oracle and it will ask for 120 precursor orbs per power cell. If you have enough precursor orbs, give them to the Oracle; otherwise go out and look for enough precursor orbs. You need 240 precursors for both power cells.
