Yes but remember that 100 amps x 12 V = 1200 W
1200 W / (746 W/hp) = 1.6 horsepower

10 hp is 620 amps at 12 V

The key to making a system like this work is the trade-off of efficiency of 
the electric to thermal conversion vs. mechanical to thermal of a 
refrigeration system.  DC to DC voltage boosting will decrease the current, 
but create a voltage hazard akin to an ignition system and add another 10% 
of inefficiency.  I'm all for it but a lot of engineering is needed; it is 
not a "bolt-on" of an existing technology.
