What-If 0130: "Snow Removal"

What if there was a forum for discussing these?

So to provide the energy for the snow-melter contraption, he would only need one carrier, and only slightly over one of those reactors (so total carrier output 1100 megawatts. Or maybe one A4W reactor and the smaller reactor on a submarine. That'd be cool. I work in naval nuclear propulsion on the by and by.

This has been bothering me, as well. I don't know how much power the A2W made, but with eight of them I'm guessing the total wasn't much less than the two A4Ws. Perhaps he found the A1W's output but didn't get to the "there are eight of them" part of the story. http://en.wikipedia.org/wiki/A4W_reactor
What did you bring the book I didn't want read out of up for?

after all, we don't use flamethrowers in our kitchens.

Do you know what a flamethrower is?
Unless stated otherwise, I do not care whether a statement, by itself, constitutes a persuasive political argument. I care whether it's true.

Well, how else do you make it?

Not actually a flamethrower. That's just an oversized torch.

A flamethrower actually throws flame -- that is, squirts a flammable substance which is subsequently ignited.

Yeah, the fact that the YouTube title says "flamethrower" does not mean the video actually depicts a flamethrower.

This is what a flamethrower does.

I joined the forum to correct the power output of the carrier, but I see other nukes have already been here haha. MM2(SS) Halsey

How about mounting a small black hole on the front of your car to suck up all that snow?

Well, depends on your definition of "small".

A "small" black hole will emit significant Hawking radiation...the smaller, the hotter. A black hole of 760 million metric tonnes (around twice the mass of the entire human population) will produce the requisite 574 MW of power to melt the snow for you, and will last you approximately 20 years before evaporating completely. Of course, the longer you use it, the hotter it will become, so that's something to be careful about.

Of course, that black hole is going to be only 2.26 femtometres across, roughly the size of a proton. At 760 million metric tonnes, that means it will exert 1.9e17 trillion gigapascals of pressure on whatever you're using to hold it. That's about 100 million times more pressure than what you'd get inside a neutron star.

If you want to use a larger black hole to actually suck it all up, you're going to end up creating a nasty accretion disc which will tend to inhibit your suction capabilities. While also destroying the Earth. Which, I suppose, does fit under the category of "snow removal".

So a follow-up question:
Here in Massachusetts, the snow obviously has wreaked havoc on the transportation system. The jet-engine clearing device on the T was a joke. Here's what I'm wondering: in the T tunnels, you have no snow on the rails and a working electrified 600V third rail that carries enough amps to move several trains. Assuming a T-train cart, with a plow that can get all but 1" of ice off the rails, how much power would it take to have the rail-cart with plow radiate heat on the 2 rails + the third rail? Doing it using the electricity means not having to fuel up jet fuel. It seems firing up a jet turbine engine to blow at the rails was really slow and not very effective (took 3 days to finish the Orange Line north, which is what, 3 miles?)
