Document Summary

1 calorie = 4. 2 joules) list, and justify, what assumptions you choose to make! Use the energy conversion factors on slides 3 and 4 and the formula on slide 17. (cid:120) refer to spreadsheet, 0. 368 big macs. Use the energy density table on slide 16. (cid:120) refer to spreadsheet, 0. 093 milligrams: ever since einstein published e=mc^2, the world has been trying to harvest fusion and fission energy. We are still working on fusion, because it is estimated to release 3-4 times the energy of fission. This is a mind-boggling amount of energy, really challenging to visualize. Most of us have sat around a camp fire however! 3, 4, and 16. (cid:120) refer to spreadsheet, 500 thousand campfires to match fission energy. To compete with a car, the horse will need twice that many calories. For reference, grass has about 245 calories per pound. Refer to slides 3, 4, and 16. (cid:120) refer to spreadsheet.
