Abstract. The Hydride Earth model predictions of geoneutrino flux and intrinsic Earth heat flux are discussed. The geoneutrino flux predicted by the model can be adjusted to the experimental one. The predicted intrinsic Earth heat flux is significantly larger than model dependent experimental value obtained under assumption that the main heat transfer mechanism is a thermal conductivity. We introduce an additional mechanism of heat transfer in the Earth's crust, namely the energy transfer by hot gases produced in the Earth crust at great depths. The experimental data supporting this idea, in particular the temperature profiles measured in the Kola super deep borehole, are discussed.

We discussed the idea of big value of potassium abundance in the Earth. We showed that Borexino single event spectrum permit the potassium abundance up to 2% instead of the CNO neutrino flux contribution. Works [5], [6] introduce the idea that fast α particles are appeared in nuclear processes in solar core plasma. The reactions of these α particles with CNO nuclei can suppress the CNO neutrino flux. We demonstrated the connection between the existence of Earth’s electric field and the big value of 40K geo-neutrino flux because the both phenomena are the sequences from Hydride Earth model.
