To understand the incredible potential of low energy nuclear reaction (LENR) and nuclear energy in general, you must grasp the concept of energy density. Put simply energy density means the amount of potential power contained in an energy source or the more density, the more power.
The best explanation I’ve seen of this concept so far is in Robert Bryce’s fascinating new book Smaller, Faster, Lighter Denser, Cheaper. In the book, Bryce shows that density is the key to energy success and demonstrates that most green power sources simply lack the density needed to power our modern technological civilization.
Among other things, Bryce notes that wind turbines provide an energy density of .9 watts a meter. In contrast a cubic foot of natural gas provides 1,031 British Thermal Units (BTUs) of power or heat. He estimates that a barrel of oil contains the equivalent of 529 watts of electricity and 1,000 cubic feet of natural gas provide the equivalent of 3,819 watts of electricity or 36.79 kilowatt hours of electricity. A standard lithium-ion battery like those used in electric cars or laptops has an energy density of around .25 and .73 kilowatt hours of electricity.
