Paul Pickering considers the technical challenges posed by cold fusion or Low-Energy Nuclear Reactions.
Here's the active element in the Parkhomov experiment, called the “reactor”. It uses an Al2O3 ceramic tube 120mm long, 10mm outer diameter and 5mm inner diameter, wound with nichrome heater wire. The tube contains 1g of a powder composed of nickel (10%) and lithium aluminum hydride (90%), both readily available from chemical supply houses.
