> Random idea 2: Develop advanced solar panels that can efficiently harness energy from moonlight and starlight in addition to sunlight.
Even if you could get 100% efficiency from panels (today they are 30%) the solar power from moonlight and (much less) starlight is insignificant compared with the power of the sun.
> In average, we get 1 milliwatt from the moonlight which is 1/300,000 of the Sun's 342 Watts (averaged over places, seasons, day cycles). That's about the same what I got for the total strip of stars in the Milky Way – 3 parts per million of the Sun
