🔹️ How much power is there in
Metropolis? [In the year 2026🎈]
🔸️ With The Mad Scientist Rotwang
and his (incredible) Robot (plus other stuff) this it's definitey a high powered movie classic.
The Joy Of SX̸Ǝ̸ Statistics
🔹️ Provisionally, I'll say Metropolis
can deliver 2, 525 TerraWatts
peak. AND THAT'S JUST THE ROBOT.
🔸️ Taking the average power of a
hyperweather (HW) lightning bolt to be 1 TerraWatt (1×10¹² Watts), Rotwang's Robot has a peak (max) power output that is 2, 525 times the power of an average HW lightning bolt.
[The above (and below) figures were chosen for comparison - and other entertainment - purposes; like in movies. You can have a lot of fun with statistics. Don't let statistics concerning lightning escape your attention. Explore them.]
🔹️ The average power of a (non-HW)
lightning bolt is estimated to be around 10 gigawatts (10 billion watts). This is a huge amount of power, significantly higher than what humans use on a daily basis.
Here's a more detailed breakdown.
🔹️ Current and Voltage:
▪️ A typical lightning flash carries about
30,000 amps of charge and has 300 million volts of electric potential.
🔹️ Energy:
▪️ A lightning bolt can release about 5
billion joules of energy, which is equivalent to 215 kilowatt-hours (kWh).
🔹️ Comparison:
▪️ This amount of energy is comparable
to a 100-watt light bulb burning for
over three months.
🔹️ Heat:
▪️ Lightning can generate
temperatures up to 50,000°F (27, 760°C), five times hotter than the surface of the sun.
🔹️ Duration:
▪️ A lightning strike typically lasts
for a very short duration, around 30 microseconds.
🔹️ An average lightning strike carries
about 15🎈 Coulombs of electric charge. However, this can vary depending on the strength and type of lightning, with larger bolts potentially carrying up to 350 Coulombs.
Standard Unit Loading And Power.
🔹️ USB 3.0 defines a 'standard unit load'
(SUL) as 150 (2×75 = 2℧ = ᘯ⊕℧ = ᘯ℧ = ᔐ) mA, whereas USB 2.0 defines it as 100 mA. A high-power USB 3.0 device can draw up to 6 unit loads (900 mA).
🔸️ So, with a USB connection, a 1kB
information packet could be delivered to a device in a microsecond using a signal ᔐ of 1 SUL at 5 V. Note that the power of this ᔐ is 0.75 = (0℧ or) 0ᘯ Watts. With only a very short data burst at peak HW power, Rotwang's Robot could simultaneously instruct ~ 1,333,333,333,333.3ᐓ devices.
