Any publicity is good publicity?

Yeah the first issue is in theory solvable, but they never managed to do it, not in a practical manner at least (huge cryocooled superconductors is probably not very practical)

The forces are from the immense magnetic fields, two parallel wires with current in opposite directions will repel eachother, so the rails are trying to move apart from eachother

This plus the heat causing material expansion plus the rails needing to be very straight for it all to work, and you end up having a bit of an engineering headache on your hands

But yeah it's mainly when you build large ones meant to fire things at really really high speeds, maybe we'll find a way to improve it one day, but for now it's sadly dead in the water (in the military sector at least, but they tend to be the main driving force behind technology that fires things)

The issue is that large scale railguns tend to self destruct, either from the heat or from the immense forces, so it can only fire a few shots before it needs extensive maintenance, and the time it takes to recharge is quite long in most practical applications (warships and such) which is why the american military has given up on the concept.

For launching stuff you have the same issues, except you now the payload isn't a solid piece of metal but an intricate component which somehow needs to survive the insane acceleration (unless you use a really long barrel)

The "squirrels do not transmit rabies" statement from the department of public health sounds reassuring, until you realize it's an american department of public health

Yeah those 5 people definitely have rabies now
