Icy Kuiper belt objects (Pluto and Cheron) have potential Geysers activity just like Enceladus (below) or Triton. According to Quantum FFF theory this should be explained by the ZPE energy production of water and heat of internal crashed comet nuclei, just as is assumed to be active in the earth and as sunspots in the sun.
Pluto’s icy mountains (hight 3500 m. above) are evidence for geological activity possibly driven by internal internal energy sources.
