In the same time you could heat a 600 lb block of concrete the same amount, or melt 30 lb of ice, or evaporate about 2 litres of water. It will take about 150 ml of gasoline, or 2/10 pound of natural gas, or the energy in a roughly 75 pound deep-cycle battery >>>>>>>>>>>>>>>>>>>>>>>>> With all that in mind, I am of the understanding that stopping an average vehicle from 60 mph requires the conversion to heat of enough energy of motion to boil 2 liters of water. Has anyone worked on a direct water-heat exchanger that runs through the brake rotor? Or drums? Not only would this cool the brakes, but if set up in a recirculating fashion with the tank, this could quickly raise the temperature of a full tank of water to the boiling point within a few minutes in stop 'n' go highway driving. You could have hot water any time you wanted, without the abysmal, loathsome inconvenience of warming it on the stove. Happy Friday. G.
