This article highlights “Type-B energy technology” isothermally utilizing environmental heat energy to generate electricity, showing its: a) basic system designs, b) equations, c) calculations, d) experimental measurements, and e) live experimental demonstrations, for an asymmetric function-gated electricity generator system comprising an exceptionally low electron-work-function surface as an electron emitter and a space gap that permits the isothermally emitted electrons to travel ballistically to a collector. The equations, calculations, experimental measurements, and live experimental demonstrations showed that the type-B energy technology can utilize the limitless environmental heat energy to generate electricity without requiring any temperature gradient as long as the electron-work function of the emitter is substantially lower than that of the collector. Using a pair of an exceptionally low electron-work-function (0.70 eV) emitter and a high work function (4.6 eV) collector at 298 K, its electricity production density could be . Its capability to ceaselessly forever power many electronic devices such as mobile phones and AI machines has paramount scientific and practical implications to help “ultimately liberate all peoples from their dependence on fossil fuel energy, thus helping to reduce greenhouse gas CO2 emissions and control climate change” towards a common shared sustainable future for humanity on Earth.
