However, the thermoionic emission process is very inefficient, and I do not see how it is related to producing light in any way.

Heat and nanotech dont go well together. <br /><br />Optical nantenna would be a device thats needed here. <br /><br />Then again, microwaves are better. Almost zero loss trough atmosphere (compared to light), technologically doable now. <br />Rokhttps://www.blogger.com/profile/01594627296669652306noreply@blogger.com
