Well, when you ignite a natural gas turbine, you input a few hundred watts of power, and you get megawatts of power out.
The idea here is that you put in some energy, something (LENR?) happens, and you get more power out.
They’ve laid out how to do it. If - big if - it works, we’ll have independent verification soon enough, and then the world changes...
When one of these things shoots its wad, that’s it. It has to be rebuilt. It’s more like a battery than a nuke plant.
