The observed luminosity -- temperature relation of clusters is considerablysteeper than that expected from a simple scaling relation. Although extraenergy input is a likely solution, its source has not been identified. Wepropose intracluster supernova as a possible source, and also predict thesupernova rate in intracluster space as a critical test.Comment: 3 pages, PASJ in pres
