Hello. So what I'm currently simulating is laser transmission through space, need to incorporate Heisenberg's Uncertainty Principle for laser divergence over a distance in space "a vacuum", energy is conserved but it diffracts due to photons from emitter not having parallel line paths. Got tropospheric and stratospheric attenuation done, need to look into mesospheric and ionospheric transmission though for now it looks to be negligible.

So to answer your questions. Microwaves are not attenuated as highly compared to laser however they diffract and scatter highly through the atmosphere, a 2km SPS microwave transmitter capable of GW power transmission requires a 100km+ diameter set of ground based rectenna's, from my calculations. Whereas laser does not scatter/diffract as much, however it is highly attenuated in the TROPOSPHERE and STRATOSPHERE only. But these 2 layers only add up to 50km from ground, whereas the atmosphere for Earth ranges from a border of 80km to Ionosphere ranging to ~1000km. Hence if I transmit laser through the majority of the atmosphere, it keeps a fairly coherent and efficient beam, capture it in the stratosphere via a "suggested" airship with specific band solar PV to increase efficiency of laser capture, then power a microwave transmitter to transmit the power 50km which won't diffract much, or theoretically use a 20km high voltage direct current cable tether, made possinly aluminium or carbon nanotubes in the future. Very high efficiency wireless energy transmission, the main losses come from conversion from conversion components themselves, not the energy transmission.

Anyway too much info I have given away ;) But it's unlikely you can steal my idea and do anything with it haha.
