Manufacturing Begins For Fusion Reactor Parts 

by Michael Keller

The first components of what will become the world’s largest experimental nuclear fusion reactor are now being manufactured around the world. Once it starts operating in 2020, the multinational ITER demonstration power plant will help scientists understand how to fuse hydrogen nuclei together to make energy, the same phenomenon that powers the sun.

At the heart of the project is the 25,400-ton tokamak, a machine that uses magnetic fields to confine a plasma that burns at 150 million degrees Celsius. The giant magnets used to corral the plasma are now being manufactured at a facility in La Spezia, Italy, as seen in the gifs above and video below.

Advance Brings Fusion Power Closer

by Norman Rozenberg

Lawrence Livermore National Laboratory scientists announced they have made a significant step towards achieving ignition, a process needed to make fusion energy viable. For the first time ever, researchers say they have gotten more energy out of fusion fuel than what they poured into it to start a reaction.

Inching Closer To Fusion
This is a room within the U.S. Department of Energy’s National Ignition Facility, where researchers are working to ignite a self-sustained fusion reaction. 
The room contains the preamplifiers for the facility’s 192 lasers that fire billionth-of-a-second pulses onto a tiny target. The lasers deliver 1.8 megajoules of energy and 500 terawatts of power—1,000 times more than the United States uses at any one moment. Their target is a tiny capsule that is heated and pressurized to conditions similar to those found in the sun’s core.[[MORE]]
The product of achieving their objective will be a reaction that produces more energy than that which is put into starting it. They say that experiments in September got them much closer to their goal. If their work is successful, it could usher in a revolution in abundant, clean energy.

Nuclear Fusion Rocket Could Reach Mars in One to Three Months

by Michael Keller

University of Washington researchers are working on a new design for a fusion-driven rocket that they say could cut a round-trip voyage to Mars to 90 days or less.

“The future of manned space exploration and development of space depends critically on the creation of a dramatically more proficient propulsion system for in-space transportation,” wrote the project team in a paper on their propulsion design. “Nuclear fuel contains energy densities that dwarf the energy of any chemical combustion. The fusion-driven rocket … offers a realistic approach to fusion propulsion systems.”

If their design works as they believe it will, their engine could propel a Mars-bound spacecraft at more than 12 miles per second. If they were able to build a working craft by 2020, the red planet would be around 36 days travelling time from Earth at that speed. According to astronomy professor Courtney Seligman, in October of that year the two planets will be a relatively close 38.6 million miles apart.
