Assume that the annual US power consumption is 2 x 1020 Joules:

a) If this energy could be supplied by combining pure matter and antimatter, calculate the total mass (antimatter + matter) that would be required to power the US for 1 year.

b) Gasoline has an energy density of 3.4 x 107 Joules per litre. How many litres of gasoline would be required to power the US for 1 year?

c) Gasoline has a density of 0.75 kg per litre. Compare the mass of gasoline that would be require to power the US for 1 year with the mass of matter + antimatter.

According to a recent study1, it takes between 5.6 and 10.2 million joules of energy to produce a 1 L of bottled water (for simplicity, let’s assume the value is 7.9 million joules for 1 L). To produce 1 L of tap water takes about 0.005 million joules per L for treatment and distribution a.) Americans consume approximately 33 billion L of bottled water per year. Assuming gasoline has an energy density of energy density of 125,000 BTU/gallon, calculate the...

Burning 20 tons of coal provides about  joules, which is approximately the annual energy requirement of an average person in the United States. If this amount of energy was provided by the electricity generated by the fission of uranium-235 in a nuclear reactor, instead, what mass of natural uranium would be required? About 0.7% of natural uranium is uranium-235 (almost all the rest is uranium-238, which does not fission like U-235 does). Assume that the fission of each U-235 atom provides...

The US annual consumption of electricity is 3 ⇥ 1012 kWh. If all the electricity were produced by bituminous coal, with an energy content of 2.81 ⇥ 1010 J/ton, at an efficiency of 40%, the amount of coal burned per second would be: (a) 1828 tons / second. (b) 30.4 tons / second. (c) 12.2 tons / second. 1 kWh of electricity from coal, assuming a plant with 40% efficiency, energy content of coal of 2.81⇥1010 J/ton, and coal made...

In this exercise we will consider two coal-fired power plants and a solar thermal plant, in order to compare their power densities, i.e., their power output vs. the amount of land they occupy. This method of comparison of diverse forms of renewable and non-renewable energy systems was pioneered by Vaclav Smil of the University of Manitoba in Canada. The first coal plant is highly efficient and is optimally located, next to a mine that supplies high-quality coal from a thick...
