Tokamak Oxford

Shrove Tuesday I was at Tokamak Energy. All bundled up because it was freezing cold in Oxford. The whole machine is housed inside this huge warehouse, which has structures and cranes inside it to move machinery around the building.

 

We got an introductory talk about Tokamak's spherical Tokamk from the chief engineer, and one of the senior data analysts. 

Here's what the boards had on them. 

If I understood what I was told, the fusion reactor is very much a science experiment, requiring the complicated machine to be partially disassembled to allow them to upgrade parts for the next round of tests, which are going to be run next year.

Here's the core of the Tokamak.

I did ask about the whole fusion has been 50 years away promise, and while they said they can deliver a prototype working fusion reactor by the late 40s, early 50s, it's going to cost big money, and that might be a problem for profitability.

Anyway, it was a fascinating tour.
