Where I toot from#WithAltText@StefanEJones @foone @DenOfEarth
Oh, I watched all the episodes of The Time Tunnel. Especially the one with the Japanese attack on Pearl Harbor.
When the attack happened, my father was a little boy living on Hilo, the island next door to Pearl Harbor.

Nikolai Kardashev was a Soviet radio astronomer and astrophysicist who wanted to know how one could even detect extraterrestrial civilizations at all, the “SETI problem”.Kardashev Scale
-0.48 A civilization that is able to harness the power of one manual laborer. ~17W
0 harness the power of 60,000 manual laborers. ~10^6W
1 harness all of the power available on a single planet. ~10^16
2 harness all of the power available from a single star. ~10^26
3 harness all of the power available from a single galaxy. ~10^36
4 harness all of the power available in the entire universe. ~10^46 -
Nikolai Kardashev was a Soviet radio astronomer and astrophysicist who wanted to know how one could even detect extraterrestrial civilizations at all, the “SETI problem”.In 1973 Carl Sagan estimated that humanity is currently around Type 0.7. He derived the following formula by interpolation:
K = (log10[P] - 6) / 10
P = antilog10[(K * 10) + 6]
where:
K: Kardashev Rating
P: Power harnessed by civilization (watts)
log10[x] : Common logarithm of x
antilog10[x] : Common antilogarithm of x
