Hmmm, I’m not sure I understand…
A large explosion every second has units of power, not energy. So to me this is suggesting that the train is putting out power equal to its kinetic energy per second. That’s certainly not the case — it implies that the train is powerful enough to accelerate to the speed in 1s, which is definitely not true.
But that’s just my interpretation.
50kW class laser.
Another source claims 1um wavelength with individual 1.5kW lasers in a hex pattern — unclear if it’s a phased array (would be awesome) or just trained on the same target (source mentions they are “combined using a mirror” so probably the latter).
Sounds like maybe high power YAG?
