It may not seem like much but it's a harbinger of future development that may make things a lot easier. I think.
Well, highly efficient MHD plasma to electricity conversion might be something amazing and science fiction like for some, but for me is very old news and even many of the conversion difficulties and velocity issues mentioned in the paper that is linked in the ppt (which is the most interesting part of the ppt, but I had already downloaded a weeks ago) are known from the 1970s so I am hardly impressed by that aspect of the work. Of course It is a crafty and neat engineering lab gadget, no doubts, but the elephant in the room is how much energy does it consume to produce the plasma. I haven’t been able to gather that from the paper and without that key part of the data the work is not impressive. It is said in the introduction that the energy output of the plasma is 250 times the energy input to form it, and this is said as if would be a proven fact but that’s where lies the whole controversy, If this gadget is capable of that, there is no way to tell from the data provided.
