Tokamak Energy has published a set of pictures of their ST40 device as a status update. The structure of the tokamak can be seen quite nicely. Soon they will cover everything with the outer vacuum chamber and connect all services to it. https://www.tokamakenergy.co.uk/update-construction-of-st40-is-...

This is quite a big announcement. There are also interesting things going on elsewhere. Tokamak Energy will soon get their ST40 device ready. LPP Fusion will switch to their beryllium electrodes in a few months time and the results with that will be interesting to see. TAE is working with their late...

I admit that I have looked every now and then to see if the current patent application has been accepted, but I have not found any news on that. I have also not found any new patent application.

The presentation Physics objectives of PI3 spherical tokamak program http://generalfusion.com/wp-content/uploads/2017/08/EPR2017-Howard-PI3-Physics-Objectives.pdf contains this summary of the plans at General Fusion: Plasma Injector 3 Objectives: • Explore the physics of MTF reactor-scale plasmas • ...

Tokamak Energy has published a presentation on their plans in this PDF-document http://www.tokamakenergy.co.uk/wp-content/uploads/2017/08/Tokamak_energy-TTP.pdf.

Tokamak Energy has updated their web pages with a new look and structure. http://www.tokamakenergy.co.uk/

Yes, I guess you are right in that the 500 eV is for the combination of injection and compression. But it is still for the small injector so the results for the corresponding big injector will be interesting to see. Here is an article An interview with Bruce Colwill , Chief Financial Officer at Gene...

No, it is the difference between private and government. GF is doing only what is needed to prove their design in integrated form. ... -going to a full size plasma injector (they are at 500ev and need to go to 10kev, if I am understanding the status correctly), The goal for the plasma injector has ...

• Prototype goal: achieving fusion conditions (10 keV), sub-breakeven

Well that is rather disappointing, isn't it?

It is better to have realistic and achievable milestones that you can meet, than to have too ambitious goals and fail to meet them. Small steps forward are also a good thing.
