Re: Small Tri Alpha news blurp

https://tae.com/wp-content/uploads/TAE-Milestone-Press-Release.pdf News release on TAE reaching milestone and new financing of $286 million. I believe that they are the first private company to ever succeed in getting enough money to complete all the validation steps for their path to fusion. I jus...

Re: Helicity Space

They do talk about more compression in the video and how that also affects performance. So they have several knobs to twist. I will need to find the time to check the video. My understanding on how the magnetic re-connection and compression phase should work is based on the papers on Magnetic Helic...

Re: Helicity Space

Helion is accelerating their plasmoids to hundreds of km/sec before they merge and not just 80km/sec. The slower speed is probably due to the limited length of the test machine that they are using and the lack of all the magnetic nozzle components that should help to boost speed before and after th...

Re: Helicity Space

Magnetic Helicity has become again an hot topic in Astrophysics plasma in the last few years thanks to new solar observations and measurements. Here is some more info from a research project of one of the founders: https://www.openaccessgovernment.org/research-on-self-organisation-in-plasmas/45023/ ...

Re: In a comprehensive new test, the EmDrive fails to generate any thrust

There was already plenty of hints in the past that was shaking the base of EmDrive theory. Still is always nice to appreciate the ability of Tajmar of digging into the tiny details of these experimental setups to actually identify from where the measured forces are really coming from. He did (yet ag...

Re: General Fusion in the news

The driving pistons and thicker outer vessel then is stationary and is coupled with the inner pistons with some kind of working fluid (don't know what that is and they don't say). The first impression I got from the movement of the piston in the animation is that it could be some type of magnetic c...

Re: 2021 state of the horse race: ITER vs. dark horses

How can 1,200 MWth be "low value heat"? The thermal load will be roughly 50% of that, so around 600MWth distributed more or less over all the machine. Also according the PDF they are expecting a peak heat flux of 1 to 2 MWth/m2 (or 100 to 200 W/cm2). Making a high pressure steam recovery system ove...

Re: 2021 state of the horse race: ITER vs. dark horses

Anyone understand how they get to that number? Rough Numbers: Fusion output: 1200 MWth. From the PDF I sent you some days before at page 4 : ETAe= 0.9 ETAcdc= 0.7 ETAddc= 0.85 ETAth= 0.45 So the electrical efficiency for the conversion is estimated at 45% or 540 MWe, and te expected Q is 5-8, so th...

Re: 2021 state of the horse race: ITER vs. dark horses

So the latest news for TAE is that Da Vinci, their first machine to demonstrate PB11 fusion is now set to begin operation in 2028 (see TAE thread for source). Copernicus is supposed to demonstrate "viability of net energy" by 2024/25 Prospective length for the commercial reactor vessel: 80 meters P...

Hasn't LPP already announced that they had achieved two billion degrees?
More important than temperature, the heart of their technology is the Merging Compression Heating system, and that has not yet been proven to work as expected in previous experimental runs.

Re: Tokamak Energy news

If with this upgraded ST40 they will be able to prove in certain way that the M-C heating theory works as expected it will boost a lot the confidence on the whole set up.

Re: More Helion Energy news....

They are present also in the google version.
If for any reason you can't see them on the webpage click on "Download PDF" and you will get a complete PDF of the patent as it was originally submitted to the patent office.

I found a version of their second patent that has the drawings and tables included (yay!). That one is a lot more clear on the various fuel ratios, etc and what can be achieved with them: https://patentscope.wipo.int/search/en/detail.jsf?docId=WO2015163970&tab=PCTDESCRIPTION This patent should be t...
