    Guarantee you they weren't generating a whole lot of power though.... And if you can't do that part then what's the point?

        Yeah, and we measured them to the purpose of flight... Not wingspan, or how soft the wheels were.

        So maybe we should measure technology that's about generating power by.....

        I'll let you fill in the blank.

        P.S I have a "perpetual" motions machine that can run for 30 minutes (8 minutes longer than this fusion reactor), are you interested in investing?

        EDIT: Four years ago the British Fusion reactor (J.E.T. originally built in 1984) produced "59 megajoules of heat energy" none of which was harvested and turned into electricity. The project was then shutdown for good after 40 years of not generating power.

          A fusion reactor has already output more power than its inputs 3 years ago. Running a reactor for an extended period of time is still a useful exercise as you need to ensure they can handle operation for long enough to actually be a useful power source.

            No fusion reactor today is actually going to generate power in the useful sense.

            These are more about understanding how Fusion works so that a reactor that is purpose built to generate power can be developed in the future.

            Unlike the movies real development is the culmination of MANY small steps.

            Today we are holding reactions for 20 minutes.
            20 years ago getting a reaction to self sustain in the first place seemed impossible.

                Yes, but you're asking how much cargo it can take while we're barely off the ground. Research reactors aren't set up to generate power, they're instrumented to see if stuff is even working.

                  Generating massive amounts of heat and harvesting that and converting it to power are two (or three) different problems.

                    Not equivalent. Let's measure the aircraft performance by its ability to carry passengers between capital cities.

                    It's baby steps and we need to encourage more investment. Not dismiss the Wright brothers for being unable to fly from New York to London after ten years of development.

                      Predicted fusion energy and energy actually harvested and converted to usable electricity are not the same thing. Your article is about "fusion energy" not experimentally verified electrical output.

                      It's a physicist doing conversion calculations (from heat to potential electricity), not a volt meter measuring actual output produced.

                        Agreed. But just to go along with the flight analogy proposed earlier, it took hundreds of years from Da Vinci’s flying machine designs to get to one that actually worked.

                            In 1932, Walton produced the first man-made fission by using protons from the accelerator to split lithium into alpha particles.[5]

                            We've been at this for coming up to 100 years too.

                            Let me know when they actually generate power. I don't want another article about a guy jumping off the eifle tower in a bird suit. A successful flight should be measured by the success of the flight.

                            Power generators should be measured by the power generated.

                            0 watts. Franz Reichelt went splat on the pavement having proven nothing.

                            America, the UK, France, Japan, and no doubt other places have been toying with fusion "power" for 90 years... We've created heat and not much else as far as I can tell.

                                It's almost as if fusion is a significantly more difficult problem to solve than powered flight

                                  They weren't trying to generate electricity in this experiment. They were trying to sustain a reaction. As you said in another comment, they are different problems.

                                  Converting heat to electricity is a problem we already understand pretty well since we've been doing it basically the same way since the first power plant fired up. Sustaining a fusion reaction is a problem we've barely started figuring out.

                                    Fission isn’t fusion, the first artificial fusion was two years later in 1934. That gives us a mere 332 years to beat the time from Da Vinci’s first design to the Wrights’ first flight

                                    0 watts. Franz Reichelt went splat on the pavement having proven nothing

                                    He demonstrated pretty clearly his idea didn’t work.

                                      They weren't trying to generate electricity in this experiment. They were trying to sustain a reaction. As you said in another comment, they are different problems.

                                      Converting heat to electricity is a problem we already understand pretty well since we've been doing it basically the same way since the first power plant fired up. Sustaining a fusion reaction is a problem we've barely started figuring out.

                                      I don't think we do have a means of converting this heat energy into electrical energy right now. With nuclear we put radioactive rods into heavy water to create steam and drive turbines...

                                      What's the plan for these fusion reactors? You can't dump them into water, nor can you dump water into them... I don't believe we have a means of converting the energy currently.

                                      Even if we could dump water into them it would explosively evaporate because they run at 100 million degrees Celsius. That would be a very loud bang and whatever city they were in would be gone.

                                        If you're not sure how the fire works, it seems kind of stupid to build a turbine for it.

                                        We were absolutely not sure how fire really works (low temperature plasma dynamics and so on) when we used it in caves eons ago.

                                          The idea is to have water or molten salt cool the walls of the torus from outside, and those drive ordinary turbines like any other generator. The main issue is that particles fly out of the confined plasma donut and degrade the walls, whose dust flys into the plasma and reduces the fusion efficiency. They're focusing on the hard part - dealing with the health of plasma sustainment and the durability of the confinement walls over time. Hot thing that stays hot can boil water or salt to drive regular turbines, that's not the main engineering challenge. I get your frustration where it feels from news coverage that they're not focusing on the right stuff, but what you'll likely eventually see is that the time between "we figured out how to durably confine a healthy plasma" will quickly turn into "we have a huge energy output" much like inventors puttered around with flight for hundreds of years until a sustained powered flight design, however crappy, finally worked. From that point, it was only 15 years until the first transatlantic flight.
