A TVR train draws 120 MW from the grid – as far as I can see.
A 0.5cmx1m steam plasma tube produces 300 KW or heat: extrapolating from the 2.5x1030 W produced by a 2cmx1.5km steam plasma in a lightening bolt. This produces 5 tonnes of He ions, as it does Molecular Nuclear Fusion
Every 3 minutes around the Earth, throughout the year. So 6 0.5cm steam plasma tubes will produce 1.8 GW: 300 MW from each tube. We maximise the surface area – as they did with early steam trains.
So we will produce 180 kW. Without melting the engine. The plasma tubes sit in a water bath at 8 atmospheres. My data was for 4 atmospheres, so we may get 1.5 Global Warming of steam.
We will generate 180 MW of electricity. To drive the train at 600 mph. We do need aerofoils, to press the train down on the track. As with F1 cars.
Each 100 mile journey will use 8.6cc of regular water. A frightening small volume of water.
We draw no current from the grid, once the tubes are fired up. We should power up batteries to get around this problem.
So we will produce a new generation of steam trains, that will analyte the Mallard record.
