Cycas revoluta Cycas revoluta Cycas revoluta (Sotetsu [Japanese ソテツ], sago palm, king sago, sago cycad, Japanese sago palm), is a species of gymnosperm in the family Cycadaceae, native to southern Japan including the Ryukyu Islands. It is one of several species used for the production of sago, as well as an ornamental plant. Cycads' only relation to the true palms (Arecaceae) is that both are seed plants. The Latin specific epithet "revoluta" means "curled back", in reference to the leaves. This is also called Kungi (comb) Palm in Punjabi speaking areas.

Klaipėda Geothermal Demonstration Plant fuel, and reduce CO emissions by 51,940 tons, NO by 11 tons, and sulfur dioxides by 1,160 tons per year if it additionally replaced heavy fuel oil. According to this estimate, the plant would satisfy about 10% of the city's heat demand. The potential for geothermal heating using the source aquifer arises from the Gotland tectonic belt and Polotsk–Kurzeme fault belt interface in the area, which generates thermal anomalies. The plant uses water from a well drilled into a Devonian aquifer about beneath the surface. The heat is extracted using an absorption heat pump, and circulates in a closed loop.
