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?

The first planes only flew for a few seconds.

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.

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.

LLNL has achieved positive power output with their experiments. https://www.llnl.gov/article/49301/shot-ages-fusion-ignition-breakthrough-hailed-one-most-impressive-scientific-feats-21st

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.

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.

[–] DarkCloud@lemmy.world 0 points 2 months ago (1 children)

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

[–] NOT_RICK@lemmy.world 1 points 2 months ago (1 children)

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.

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

He demonstrated pretty clearly his idea didn’t work.
