These guys built a portable battery powered 80 watt CO2 laser gun (with IR glass tube laser)
Plus they made it look exactly like Zarya’s Particle Cannon in Overwatch.
They attached a battery to an inverter to power the HV Power supply, so I am not sure how much laser time they can get but it must be very limited.
It does not have a focusing lens so it is just the raw beam coming out of the tube, but it is still pretty amazing (and dangerous)
