At the company I work for, we send signals to orbit with 1 watt, but I'm sure it could be done with less. However, it depends on how fast a datarate you want, more power can generally get you a higher datarate.
How many days does it take Saturn the planet to orbit the sun? How many days does it take Saturn the planet to orbit the sun?
18650 watts
A signal from NASA to Mars would take between 2 and 22 minutes approximately depending on where they are in relation to each other in orbit.
2050 watts
15 watts
Watts are not deadly but it would take 12 micro-watts through the heart to kill someone.
How many days does it take for the moon to orbit the earth
A small shredder 100-200 watts.
A horsepower is equal to 746 watts, so 10 x 746 = 7,460 watts.
Rule of thumb, 1 HP = 746 watts.
To get into orbit , it is 200 miles but it could be the same amount of miles to get out of orbit.
Volts don't make power. Watts do. Watts = (volts) x (amps) 1 horsepower = 746 watts
