Okay, six+ amps.  Ignoring losses, it will take about 18 hours to heat 13
gals of water 40 degrees F. (i.e. 50 litres by 22 degrees C).  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.
