You could see emisison-free, safe nuclear fusion powering homes in the near future.
- Scientists have shot laser beams at the highest energy level ever.
- The laser beams could be used to generate nuclear fusion, the same energy generated by the Sun.
- The potentially limitless energy is emission-free and safer than the more common nuclear fission.
Scientists have produced a laser shot with an unprecedented energy level that could be a key step towards nuclear fusion, the U.S. National Nuclear Security Administration said Wednesday.
The researchers, from the National Ignition Facility, for the first time delivered a megajoule of energy to a target by focusing 192 laser beams at the same time at a temperature of 111 million Celsius (200 million Fahrenheit), it said in a statement.
"Breaking the megajoule barrier brings us one step closer to fusion ignition," said the body's administrator Thomas D'Agostino in a statement.
"This milestone is an example of how our nation's investment in nuclear security is producing benefits in other areas, from advances in energy technology to a better understanding of the universe."
