“Musk insisted that he was talking about nuclear fission and not fusion, and even seems to disregard idea of nuclear fusion, claiming it’s not needed.
Nuclear fusion is the process atoms of smaller elements like hydrogen being fused to release energy. The Sun generates energy in this manner. While companies and countries are trying to replicate the process, most of the energy generated is used up for sustaining the reaction, making the technology commercially unviable.
Conversely, the nuclear fission process involves the breaking apart of heavy atoms like uranium which releases high amounts of energy as well as more neutrons that set up a chain reaction to generate more energy.
The process is commercially viable at large scales and has been used on a global scale to generate power. However, radiation leaks at nuclear power plants along with the waste generated during the fission process have led to opposition to generating power using this method.
“I think modern nuclear power plants are safe, contrary to what people may think,” Musk said. “I really think it’s possible to make very, extremely safe nuclear [power].” However, he did not specify how this could be done.
There are also other innovators in this space. Oklo, a startup company, plans to build microreactors that will use the nuclear waste from bigger power plants and carry out further fission reactions to extract more energy from them while reducing their radioactivity.
Similarly, the Bill Gates-backed Terra Power is innovating ways of generating nuclear power in reactors that could run for a hundred years.
Gates also believes in the potential of energy produced from nuclear fission. Completing the triad is Jeff Bezos.
Comment: I have long thought that fission power is the real answer to the need for clean green energy. pl
