Tokamak Energy plans to start operating its fusion reactor this spring, and claims that its first commercial prototype will be built by 2025.
http://www.tokamakenergy.co.uk/


At a fraction of the size of other nuclear reactors, Tokamak's device uses a 'spherical tokamak', which the firm describes as the 'fast route to fusion.'




Pictured is the magnetic coil structure of the ST40 with plasma (purple) inside. The magnetic coils make a trap for the hot plasma, keeping it away from the walls


Oxfordshire-based Tokamak Energy's technology revolves around high temperature superconducting (HTS) magnets, which allow for relatively low-power and small-size devices, but high performance.






Tokamak Energy faces some strict competition from Tri Alpha Energy, a rival firm that has already developed a machine that can hold hot plasma steady at 18 million°F (10 million°C) for 11.5 milliseconds.
http://trialphaenergy.com/
The firm recently received $500 million (£405 million) to created a commercial fusion reactor, that it claims will be ready be 2027.

The particular type of fusion power Tri Alpha is working on is based on heating hydrogen atoms to temperatures of 5.4 billion°F (3 billion°C) - which is hotter than the surface of the sun.

The heat creates plasma that has a mixture of electrons and ions.

When ions in a plasma collide, they fuse together to form new atoms and release huge amounts of energy.

It's a relatively simple concept, but the trick is in heating the gas to such a high temperature. Currently no known material can hold this heat.

Dorset where else eh? >>> Thats ENGLAND<<<
hope they build this in the highlands of Scotland
It hopefully give the area a few jobs
If it goes Bang no need for Scottish Independence :)
If it don't go bang the Scots cannot afford to maintain it and so remain part of Britain ( Cause we will pay for maintenance )

Whilst the plasma would be hot it wouldn't wipe much if anything out and it's not that radioactive a device either, that's why they might be mint.

Wouldn't he be a Scot first and foremost so the kilt would always be good.:)

I will believe this when I use the power from the grid. They have been promising Fusion for years, and so far have failed to meet every prediction set, have limited test units, and fail to adequately explain the operation to the point it seems more like you are watching some idiots explain how the earth is flat, chemtrails, or how we can't possibly be floating on lava. I mean walkie-talkies inside of a industrial building they leased as part of a government grant to study what hundreds if not thousands already know. Plasma is fucking hot, emits high energy neutrons, and is hard to control as nothing that touches it will stand the heat.

Umm, fucking oi! And folk that live in Dorset shouldn't make any derogatory terms about Scots. :nutkick:

The technology is inevitable but how the hell does the heat get used to produce energy? If the heat gets trapped and contained by the coils, what does it heat to produce steam for the turbines? My best mate is an engineer, does a lot of work for power stations (fossil and nuclear) and he says thats the issue with Fusion, not if but how.

I agree with all that and especially the Dorset bit.

It's not the heat they intend to extract energy from(that's used to sustain the plasma (hopefully ,this bits hard)) its the free electrons released during fusion they intend to extract.

At least that's how I thought it worked but I didn't think they had fully sussed that either.
That and at the ITER they are struggling with the physics of maintaining the plasma and reducing the wear on it's inners afaik yet these have it all sorted ,hmnnn.

The ITER isn't even fully build afaik.

And no, fusion reactors don't go bang in an overly dramatic way - at least compared to a-bomb or Chernobyl. Probably comparable to a big boiler when it goes ooops. The moment the core is breached (magnetic field collapses) temperature and pressure drop to such a huge degree, that fusion stops at once.

Though try to explain that to the avg green voter ... .

I know it's not finished I said they are struggling on the control of the plasma and I meant it :) they're still abusing Sims trying to figure out what to press when and even what else they might need to make.

High-speed footage from an experimental facility in Prague shows the dramatic formation of the plasma column inside the tokamak – the magnetic confinement system at the heart of the reactor.




Inside the tokamak at the Institute of Plasma Physics, flashes of light can be seen growing brighter and brighter as the plasma column forms and refills.

It all takes place in under two seconds – but, shot at a staggering 1,000-20,000 frames per second, the footage lasts about a minute long.

Then, it comes to a dramatic conclusion in a burst of light, followed suddenly by darkness.

‘On 20th January, 2016, the first high-speed colour videos from the COMPASS tokamak discharges were recorded by a new fast CMOS camera of the Photron Mini UX100 type,’ according to the Institute of Plasma Physics IPP.

‘In ohmically heated plasmas in a divertor configuration and deuterium as a working gas, the videos of 1000-20000 frames per second revealed formation of the plasma column, its shaping and refilling by the gas puffing, and also a plasma-wall interaction resulting in dust particles propagating across the vacuum vessel of the tokamak.’

That was really cool to watch, I was wondering what the bits of material that would burn were.

TFTR back in the 80s lead to ITER in 2007, both tokomak. Unless they have a rabbit to pull out of a hat, I have zero expectation this project is going to succeed. Lockheed started out small too but reality eventually sets in and the project is forced to grow because of physics.

They aren't harnessing the free electrons either, as new types of fusion reactors are injecting ionized argon or other gasses to control the fusion reaction and prevent the formation of free electrons.
