I was calculating the damage of weaponized high speed rail and wolfram alpha told me "infinity joules" and was confused where I messed up the math.it turns out by "high speed" you don't usually mean "light speed", which would indeed give you infinity joules.

I was joking on Tumblr that two things I think the US should do are:1. Revive the Superconducting Supercollider project (canceled in 1993)2. Build a ton of high speed rail.So why not combine the two? With a Superconducting Supercollider Train you could cut the travel time between New York & LA down from 6.5 hours to 13 milliseconds!

with the minor downside that if the brakes fail you'll hit LA with more kinetic energy than a supernova, instantly destroying the earth, then the rest of the solar system and any inhabitable worlds within 53 parsecs.

@uep true! it's like the "blow up the asteroid" problem: Instead of a big hit of kinetic energy when it hits the ground, you get millions of pebbles carrying the same energy burning up in the upper atmosphere. So instead of getting flattened you get cooked alive

@foone assuming we can somehow create the energy to accelerate the train once, if the train uses perfect regenerative braking we never have to make the energy again. And the braking energy dissipation problem is solved!

@foone assuming we don’t want to immediately liquify the passengers...about a year to wind up to that speed and then a year to slow down in the accelerator at the other end. But then we need the accelerator to be big enough that we don’t centrifuge them either we need a radius of about 61,000 au... assuming we can tolerate 1 g indefinitely

@foone the other option besides converting kinectic energy into heat would be to eject enough mass from the train to reduce speeds to the point where friction brakes would be effective.Never mind that this would probably have determental effects on the earth's orbit and would reduce the passengers into a soup-like homogenate (though to be fair the passengers may have already been converted to that state shortly after departure).

@foone in the 90s, when the LEP (large electron-positron) collider was the big thing at CERN, and before the Underground Circle Line in London was extended to not be a circle anymore, I noticed the similarity in circumference of the two things.This led me to come up with the concept of the Circle Line LEP (Large Electric People) Collider.Two trains injected from the District Line then accelerated a few hundred times around the circle, then the points switched.
