Bottom line: If LENR doesn't pan out as an electrical generating system, Atmospheric Vortex Engines are the next best thing. If LENR does pan out as an electrical generating system, Atmospheric Vortex Engines are not only still hard to beat, at 300 mil/W capital cost, 0 variable operating cost and 1mil/W fixed operating cost, but they can be used with the larger centralized energy users (there will be _some_) to relatively efficiently (up to 20%) cogenerate from the waste heat.
