陽電極

阳 = 日 + 阝 : Maud Younger and the pope want to help the good people of the anglepod and install some solar power (太阳能) panels just inside the anglepod's kitchen. The sun helps them to generate positive electric charges by shining its rays (阳光) on the panel.

电 = 乚 + 曰 : Dorothy Gale (di) is looking for a wall plug for her charger (mnemonic symbol for 电) in the anthill's bathroom (an4). She's digging up the whole place with a shovel (乚), but instead of a wall plug she finds a microphone (曰).

极 = 及 + 木 : As Joan of Arc (ji) and Yuwen Huaji (及) pass over the north pole (及) at Christmas just inside the space station's entrance (Ø2) they decide to celebrate this moment by having a little contest. Between them there is a rather large Christmas tree (木) and they decide that whoever climbs to its top (极) first is the winner.
