I don't think there's enough energy on the earth's surface to do what you're purposing. You would need to use the earth's mantle to power that shit.

A volcano powered thermal plant instead of a nuclear one if that's the case? I don't think power would be an issue, but engineering a pump and pipeline that could withstand the enormous water pressure that would be the biggest issue.

genious

No, he's talking about the power of the ENTIRE mantle
>I don't think power would be an issue
It would be. If you were just pumping the water to the top of the atmosphere, maybe a few times the total earth power net could sustain that pump . But "getting the water off earth" is a completely different story. You'd need to build a pump that outputs so much power, it accelerates water to escape velocity. And that's a shitload of power. If we had that kind of power, we could shoot a dozen rockets to mars in an hour and have them make a return trip too.

what if global warming doesn't exist?

This is borderline troll science.

The amount of water you'd have to get rid of is truly massive, even for a 2 meter rise in sea level. 720,000 km^3 is a huge amount of water. Like 31 times the volume of lake baikal.

Assuming seawater this masses 7.4 *10^17 kg.

The escape velocity of earth is 11.2 km/s

so it would take:
0.5(7.4*10^17 kg)(11.2 km/s)^2 = 1.2*10^10 megatons of tnt

Assuming we do this over 50 years, we would need a plant that could provide 29.4 petawatts. This is 2350 times the amount of power we currently use and 6% of the power the earth receives from the sun.

And this is the ideal case. The waste heat from the pump would probably be enough to be a significant contribution to global warming.

If we could do something like this, we could just stop burning fossil fuels in the first place.

It wouldn't help, because, scientifically speaking, global warming does not exist.

why exactly are we throwing away extra water?

this is the most retarded shit I have ever seen.

id rather live on an ocean planet than do this

Let's calculate this out:
The velocity to escape earth is about 11km/s. The value for ice lost over time is very roughly 80 GIGA tonnes / year. So every day you'd have to pump ~220 million tonnes, or ~9,1 million tonnes an hour.
That's about 25368000 liters per second.
for comparison, the niagara falls flow with about 2400000 l/s.
Now we can calculate the acceleration we need the water to have. We want it to blast 2,4 million liters a second into space, so the time a 2,4 kilo ton mass has to accelerate up to escape velocity in 1 second, making the acceleration 11000 m/s2, plus an extra 9.81 for gravity, and the force needed is 279,3 million Newtons. That's a shitton. There isn't a rocket engine in existence that can deliver even nearly that much thrust, they haven't even reached 10 MN yet. By putting a saturn V on that fucking stream, it would reach almost 10G acceleration, roughly 8 times what the original engines put out.

tl;dr: it`s fucking impossible. Nothing on earth can even put out that much power momentarily, and sustaining such a machine is completely and utterly impossible.

yeah lets build a big cock coming out of our planet rooted on ocean floor.

but what are we gonna do when theres so much water orbiting the planet? what if it falls back down??

>>8504746
Your idea is stupid... why not just get everyone to drink an extra large glass of water every day! That is 7 BILLION large glasses of water EACH day!!

>>8505036
We would torpedo your mom out of the pump but she'd jam it and that's the only reason this will never work

>>8505093
Not her fault, she is big boned
