  • Maybe (3,2) is wanting you to notice the sun in the picture - or is it the eye of horus?

    Can the sun reflect light?
    Hypothesising that it probably can, theoretically; do humans have any test / measurement apparatus that might empirically prove it against the background emissions? Do we need to wait for a ‘Disaster Area’ concert?

    sorry if this should be an NSQ, I 'm sure enough as I care that this is nothing to do with the botty-detector. But I am interested in whether anything strange happens with high(ish?) densities of light.

    Fine for electrical efficiency, but in terms of fuel efficiency I can get into an odd situation where I burn the same amount of (say methane) gas in my room, vs in a remote power station (where we might assume any heat losses are not useful). I could end up getting more useful heat out of the same fuel using a nominally less efficient gas heater vs an electric one.
