What am i missing here? physics hackers, please explain.
does their claim of reaching 8 km/s in earth's atomsphere make sense? how is it possible without an insane amount of energy?
Besides, how are you going to deliver this energy in such a short time without frying the entire system, we're talking probably 1000A+ currents flowing in insane voltages.
You'd rather use TNT or some high explosive, that's what is usually done with artillery, and even then you don't get close to 8 km/s as far as i know.

- jfengel 10mo agoNo, 8 km/s doesn't make sense. It's really hard to tell from the press release, but it sounds as if they're talking about a railgun kinda thing. Which has been discussed before, and it keeps not working out. The strains on the object are too great.
