Because no known material can withstand direct contact with the plasma. Even with the air gap the walls require a cooling system, and therefore a continuous hot stream of fluid will be generated like in any other thermal power plant.
However, at the stage fusion research is, the main problem is figuring how to create a device to keep the plasma fluid stable for long periods of time. As far as I know, none of the existing prototypes aims to be a functional electricity generator.
- exitheone 4y agoIs this not false? The plasma is so incredibly thin that it would cool down immediately the moment it touches the walls. Afaik the heat generated here is mostly due to neutron bombardment and not because of the plasma.
- ncmncm 4y agoThe plasma had better not touch the wall, becuase then no plasma. But the wall would be heated by the neutrons hammering it. Nobody has identified a material to make this wall out of. It has not even been worked on in decades.
