The secret to cold fusion is to start with properly chilled water based crystals as fuel.
Proper care of cf fuel is important as you do not want the cold fusion process to start while the fuel crystals are not in the desired fusion containment vessel. Transport the cf fuel to the containment vessel in a dry, chilled container A common household glass makes an ideal containment vessel for cold fusion. A clear glass cup is preferred over a glazed ceramic mug, or those made of Styrofoam or plastic, but any of these would function. Gently place a dozen or so crystals of the
cf fuel into the containment vessel. Place (either by spray or a gentle pouring action) a few ounces of chilled liquid water in the containment vessel. After a few minutes, you should note that the cold fusion process has started in the containment vessel. This process will continue, WITHOUT EXTERNAL POWER BEING APPLIED, for hours. |
