GLY-1103 Lecture Notes - Lecture 13: Shale Gas, Nuclear Fission, Nuclear Fusion
Document Summary
Solar- e(cid:374)ergy directly fro(cid:373) the su(cid:374)"s (cid:374)uclear fusio(cid:374) reactor, heat a(cid:374)d light outward fro(cid:373) the su(cid:374), a ti(cid:374)y portion strikes earth. Direct> conversion into electricity by photovoltaic cells, conversion into heat. Controlled fusion is currently beyond human technology (h-bombs) Gravity driven sources- energy directly from gravity, falling water for hydroelectric is most common, but tidal energy is also related to gravity. Energy from nuclear fission- certain radioactive atoms can be fragmented, yields tremendous energy, runs nuclear power plants. Earth"s i(cid:374)ter(cid:374)al heat- 2 sources, drives tectonic plated, heat lost from plates can be harnessed: residual heat from planet formation, heat from radioactivity. Creation of an oil reserve needs 4 features- Burial depth of 2-4 km heats the black shale. Heating breaks the organics down into waxy kerogen. The deeper it is the larger the ratio of natural gas to oil. Deeper than 9km produces graphite, deeper forms diamonds. Oil and gas- 90 to 160 degrees celsius.
