tfussell··on Prometheus: Fuel from the Air
My back of the envelope calculation is that 1GW for 1 year is 30PJ. Jet fuel has 42MJ/kg with a density of 0.8 kg/L for a total of around 100 million liters of fuel at 100% efficiency. An A321 holds around 30000L which comes out to about 30000 flights equivalent from one reactor. GVA had around 200000 flights in 2018 meaning about 6 1GW reactors equivalent of fuel used (obviously not all flights would be fully loaded but I don't know what a normal load is).

tfussell··on Designs that Bell Almost Used for the Layout of Telephone Buttons
Maybe. It looks like the buttons are a bit smaller with slightly more space between them.
