Just for comparison: 163 pounds of uranium would have a volume of slightly more than 1 gallon. This is with density 19 g/cm^3 This should put it in perspective: 1 gallon of uranium vs. 29,000,000 gallons of fuel oil. Simply amazing energy density.
There is nothing so easy but that it becomes difficult when you do it reluctantly. -- Publius Terentius Afer (Terence)
