Re. "with large "sails" driven by solar wind "
Did anyone do the calculations for an FRB being responsible in some fashion for the Wow! signal?
My thinking here is that there could be some combination of natural events eg narrow beam of light hitting a cloud of hydrogen causing a brief spike at 1.42 GHz ?
This is an alternate hypothesis to the one suggested about natural maser action in molecular hydrogen from those two comets, and also could account (indirectly) for the relatively narrow band and lack of repeatability.
As it happens I might be able to test this with a fluorescent tube starter and small laser: any old DVD writer would work and the IR laser can be modified to focus on the empty area at the end of the tube.
