The REAL obstacle to SPSS

Delivery of power from space requires a wavelentgh
that redily penetrates the H2O ,O2,N2,CO2 laden
atmosphere, meaning those very elements that comprise
living tissue, are the very substances we must
transmit thru, without absorbtion. Since most such
microwave transmitters are tuned waveguides cut to a
precise fraction of the transmitted wavelength,ie,
(1/4,1/2 wavelength) they are not much use
transmitting outside their designed wavelength and
would therefore make lousy weapons!
