42: The Answer to Almost Everything — Season 1, Episode 54: Where to Find Perfect Energy?

Episode synopsis

Energy from fossil fuels such as coal, oil, and gas made modern life possible in the first place; however, at the same time, it harms the climate and the environment. Can we find an energy source that provides just as much power and is always clean and available everywhere—a kind of perfect energy? In terms of energy density, nuclear power was considered the perfect energy source after its discovery. According to nuclear physicist Emmanuelle Galichet, just a few grams of uranium in nuclear fission are enough to generate as much energy as burning several tons of oil. However, as great as the benefits of nuclear power are, the risks are also significant, especially when it comes to storing highly radioactive nuclear waste. Isn't solar power the better choice?

About 42: The Answer to Almost Everything

What would we be without mucus? Can we live on water? How much does life weigh? Finding out the answers is the aim of ARTE's new science show. In a nod to Douglas Adams's "Hitchhiker's Guide to the Galaxy", where the figure 42 is the ultimate answer to all questions, 42 tries to provide the answers.
