Did you know that by pumping 10 gallons of gasoline in 5 minutes, you are transferring raw potential (chemical) energy through a hose at a rate of roughly 4.3 MEGAwatts (computed from 131MJ/gal
)? It's incredible how much power our vehicles use in comparison to the electronics we're accustomed to in our households. Bear in mind though, our cars typically only get to extract about 15-25% of that from the gasoline; the rest is wasted as overhead or vented out as heat.
By comparison, if you were to operate your house's utility power at full current, balls-to-the-wall, you'd be lucky to get 48 KILOwatts out of that. (computed from 240VAC * 200A = 48KVA, actual wattage will be lower. I got the 200A figure from the mains breaker in the circuit breaker panel down in the garage of my roommate's house)
