The Earth is in desperate trouble. The rapid growth in population and need for electricity has all but depleted the world's fossil fuels. Science has been unable to fully replace them with a safe alternative. Nuclear power helps somewhat, but is far from enough to meet the incredible need for energy. You, a member of a small group of scientists, have been recruited to witness how the Earth's future handled the problem, so that the present may solve it as well. This will be done by using an advanced, but still experimental, process which makes time-travel possible.
