Based on the calculation that 18 TW would require an annual cube of seawater \(300 \mathrm{~m}\) on a side to provide enough deuterium, what is your personal share as one of 8 billion people on earth, in liters? Could you lift this yourself? One cubic meter is \(1,000 \mathrm{~L}\).

Question: Based on the given annual cube of seawater required for 18 TW (300 m x 300 m x 300 m), find the personal share in liters for 8 billion people, calculate the mass in kg, and determine if a person can lift their share. Answer: First, we find the total volume in liters by converting the cube's volume using the conversion factor 1 m³ = 1,000 L: $$ \mathrm{Total~volume~in ~liters} = 300^3 \times 1,000 \,\mathrm{L} $$ Next, we find the personal share by dividing the total volume by the number of people: $$ \mathrm{Personal ~share} = \dfrac{300^3 \times 1,000 \,\mathrm{L}}{8 \times 10^9 \,\mathrm{people}} $$ Then, we calculate the mass of the personal share in kg, knowing that 1 L of water has a mass of about 1 kg: $$ \mathrm{Mass} = \dfrac{300^3 \times 1,000 \,\mathrm{kg}}{8 \times 10^9 \,\mathrm{people}} $$ Finally, compare the mass of the personal share with the average human lifting capacity (around 50 kg). If the mass of the personal share is less than or equal to the average lifting capacity, the person might be able to lift it; otherwise, it would be improbable for them to lift the determined volume by themselves.
