  Steven Jones et al. reported to have observed nuclear fusion at room
temperature. They observed this "cold fusion" by electrolyzing heavy water.
Later experiments confirmed these observations. These experiments confirmed the
generation of strong electric fields within the deuterided metals. These
electric fields accelerate the deuterons to keV energies and allow the observed
nuclear fusion. Roman Sioda and I suggested a theoretical description of this
nuclear fusion. Our "extended micro hot fusion" scenario explains how nuclear
fusion can be generated over a long time within deuterided metals. Moreover we
predicted the explosion of large pieces of deuterided metals. This article
reviews the "cold fusion" work of Steven Jones et al. and discusses the
fracto-fusion scenario. I show that the extended micro hot fusion scenario can
explain the observed neutron emissions, neutron bursts, and heat bursts.
