On a side note, some calculations:
Energy density of Diesel/Gasoline: +- 50 Mj/kg
Energy density of Biomass: +- 25 Mj/kg
Density of oil: 0.8 g/cm³ ==> 0.8 kg/ dm³==>0.8*10
12 km³
Meaning: 12*10
12 kg oil.
Therefore required Energy input: 300* 10
12 MJ
Average output of 1 Thermonuclear power reactor: 1000 MW* = 525600000 MJ/year
Approximate amount of plants: 570776
I suspect I have made some errors there. Otherwise, this is the end of humanity. And the planet.
*Electrical energy. Thermal energy is 3 times higher.
((Why would you use ion engines. We have nuclear reactors. Orion drives are a thing.))
the explosive required to move a planet or moon are immense, far more than earth could resonably produce. i plan to use nuclear impulse to move the NEOs the ion engines are so we can adjust the orbits of planets and inarticulate moons in the future an ion engine can just be turned on and run indefinitely
Uhm nope. A ion engine still uses massive amounts of energy. After all, it accelerates particles using massive magnetical field. However, unlike a nuclear warhead, it takes a lot of time to produce any meaningfull amount of force, while most orbital maneuvers are more effective with instantaneous bursts.
yes but they can be powered by sauces such as solar which is effectively limitless, if we detonated all of the earths nukes on the moon it would barley move it. if we constructed a colossal ion engine powered by immense banks of solar panels and ran it for 20-30 years we could barly move it. the mass of the moon is (7.34767309 × 10^22) kg
the erth curentl has around 17,000 nuclear warheads. lets say they are all the size of the tzar bomba 50 megatons
that equates to 850 gigatones or roughly 3.5x10 to the 21 newton/meters
the momentum of the moon is about 7.5x10 to the 25 newton/meters more than 2000 times as much with 17000 50 megaton bombs you could change the moons velocity by. (3.5e+21[impulse of more than earths entire nuclear arsenal)/(7.34767309 × 10^22[mass of the moon])=0.04763412793 ms-1.
my math could be of your welcome to check it
Yup, I know. Moving vast objects is kindoff hard. Even if we detonated all nukes ever in existence, we wouldn't make a dent. Point is, a single nuke detonated at the right moment, on the right place of the right asteroid can shift it's trajectory just enough to turn a near miss into a hit. Additionally, it will shatter the object, making stopping it significantly harder
