Starlight plus airglow is at least 6 orders of magnitude below sunlight. Granted, it goes all night, but it seems like 4 watts per square meter is still 3 orders of magnitude above photoelectric gathering of starlight.
That 4 watt number comes from a confused paragraph and it is possible the journalist broke some numbers while handling them.
- Retric 7y agoYea, I was using 64 nanowatts * (1,000,000 making what assumptions?) = 0.064 watts vs a theoretical ~.001 from starlight. It seems unlikely you could improve the system by 64,000,000 using ambient temperature at night, operating extremely close to a theoretical maximum regularly, and be cheap enough for 4w/m to be useful.
