Title: Potassium Neutrino Detection

Abstract: There is great interest in detecting the geo-neutrinos from potassium-40. After uranium and thorium, potassium is the next most important radiogenic source of Earth's heat. The possibility that substantial amounts of potassium reside in Earth's core makes detection of potassium geo-neutrinos all the more enticing. A brief examination of possible ways to detect potassium-40 geo-neutrinos is presented.
