When one thinks of nuclear power, thoughts often include nuclear fission weapons (AKA atomic bombs) and their dangerous consequences. However, new research in sustainable energy production indicates that another type of nuclear energy could be an infinitely-abundant energy resource for the planet. It’s called fusion. Though challenging to produce, fusion’s high-energy yield and limited by-products make it an important resource to consider for the future. What is fusion? Nuclear fission is when a heavy atom, such as uranium, breaks down into smaller parts.
