How much energy is in one gallon of gas, compare this to quantity of energy in one gallon of rocket fuel, voila, your answer!!!
The energy content of a gallon of salt water would depend on the concentration of salt in the water. On average, seawater contains about 3.5% salt. Using this concentration, a gallon of salt water would contain very minimal energy in the form of trace amounts of potential thermal energy due to the dissolved salt. It would not be practical to extract energy from a gallon of salt water in this context.

One US gallon = 114,000 to 115,000 Btu = 121MJ depending on type.
Gasoline can generate roughly 20K BTU/lbm. There are 6 lbm per US gallon.
1). You don't mean 'power'. You mean 'energy'.'Power' is the rate at which the you pump the energy into the water. You can put it in fast (high power),or you can put it in slow (low power). The total amount of energy it takes will be the same either way,but it'll take longer at low power.You don't pay the electric company for power (kilowatts). You pay them for energy (kilowatt-hours).2). The answer to the water-boiling question completely depends on the starting temperature of the water.
One gallon of power is approximately 8.3 pounds, so the energy released, when 1 gallon of water falls 10 feet, is 83 foot-pounds, which is equal to 0.31 watt-hrs. If this energy were mechanically converted to electrical energy, approximately 40% losses would occur in converting the falling water into rotational, mechanical energy by a Pelton wheel or other water impeller, and about a 5% loss in conversion of rotational energy to electrical energy by a generator. So the extracted energy would be about 50%. Of that 0.31 watt-hours of energy, about 0.15 watt-hours would be delivered in the form of electrical energy, and the other 0.15 watt-hours would be lost in the form of heat.

Depends on how you use it.. According to Einsteins equation E=mc^2 (energy = mass * the speed of light squared), 1 gallon of water is equal to 326 petajoules. The world consumes 15 terawatts (54 petajoules / hour). -HowStuffWorks.com 1 Gallon of water = Enough energy to satisfy the world's energy needs for ~6 hours.
