Business Quote by Gerard K. O'Neill

““Electricity has just two disadvantages: it is difficult to store cheaply, and it can be transmitted easily only on high-voltage lines, above the ground and visible. Automotive lead-acid storage batteries are as cheap as mass production and the cost of materials will allow, yet their cost for storing an hour's worth of energy coming off the power line is over two thousand times as much as the utility company charges for that energy. Multiple recharges can't even come close to bringing that factor down below about three. There is a radically different type of battery, using liquid sodium and liquid sulfur as electrodes and solid sodium aluminate as an electrolyte (yes, I said that the right way round) that is now getting substantial research. Theoretically, it could store as much as seven times the energy per pound of a lead-acid battery. Sodium-sulfur batteries have to be heated above normal outside air temperatures - a disadvantage that will probably make them unusable in vehicles - but they could find use in central power stations to supply peak loads.””
