Im with Peatmoss here don't give up man!! Spraying the tops of the plants with water every 30 min or so certainly helps. How did you loose power? Did a power line snap Im assuming? According to studies N. Macrophylla can live as a intermediate for a certain time while still pitchering and growing. I just got a doghouse AC unit (yeah, they do exist) which Im using to keep the Nepenthes cool. Maybe you could use this for consuming less power? Ill have to check into how much it consumes.
