Scientists have been trying to make fusion power for 50 years. While knowledge has constantly advanced, it's unclear if the technological hurdles will be overcome anytime soon. It takes a lot of energy to make a process hot enough for fusion. However, if it works, fusion will produce more energy than is required to make it. Scientist believed that fusion will have no waste products-no greenhouse gases or long-term radioactive waste.
They also believed that fusion power plants will be safer than fission power plants. With fusion, there is little chance of melting down or releasing radiation. while fusion reactors would still be radioactive , most scientist believed that the reactor elements would only be radioactive for 50 to 100 years. The radioactive elements from fission reactors, on the other hand, will stay radioactive for thousands of years.
