>the sun beams a total of 120,000 terrawatts per day onto our planet. That's 10,000 times the amount that flows through our industrial civilization.

Should be "terrawatts", not "terrawatts per day". (I stopped reading there. There 100s of 1000s of people who know enough physics never to make such a mistake. I'll read one of them instead.)

While you're at it shouldn't it be "stellar power" etc? Unless the aliens are supposed to be building a Dyson Sphere around the Sun which would be decidedly easier to observe.

"terawatts", not "terawatts".

[mcantor]

'"terawatts", not "terrawatts"', not '"terawatts", not "terawatts"'.

Although 'terrawatts' is a rather charming play on the word, considering the context...
