I posted this OC 8 months ago, today i see this in my YT feed:

ok so the giant battery is in the tank, guess how big a cable would have to be? You’re not putting that on a quad
edit: it’s also impractical as hell to tether drones when most roads get netting installed over them, just saying
edit2: why not just put the laser on the tank? fry the drones around you directly instead of hoping you cut the comms in the fiber optic lines
not very
I can show you a chunky 500W cable for a pc power supply, would be just as relevant. Look up cables of actual laser power supplies, they’re big and relatively dense, and we’re talking about tethering a quad, it’s not gonna fly well with that dangling.
This man has never heard of ohm’s law
This ohm’s law?
Not a man but I take your point, consider that this drone and the cable is gonna get peppered like crazy. Plus you don’t want it tangling up
the tank has a giant gas turbine why do you need a battery
Find me a tank with a 5kW turbine
edit: i misread the units yall don’t stone me to death
The battery isn’t the issue they were talking about. They meant “so instead of batteries on the quad you’re powering it from the tank.”

The gas turbine in an Abrams produces 1100 kW

If you mean a dedicated turbine producing 5kW of electricity then it already has an accessory gearbox drawing up to 75kW out of the 1100 for peripherals. I doubt they’re currently generating (pun intended) huge amounts of electricity, but the drive is there for exactly this sort of purpose.
A 5kW alternator seems to be about $700 on ebay

If a reasonably skilled engineer cant fit that there’s something wrong
My bad, i misread the units
It wouldn’t have to run at full power all the time, just when actively defending against a drone. There are lots of other harder to solve issues.
Ok and? Still needs batteries and cables to withstand peak power, still needs to be tethered somehow, still needs another crew member constantly flying it. Not to mention being this close to combat and to the ground, you better have some insanely good lens protectors or that laser is gonna be out of commission after any shrapnel lodges itself in.
Completely made up idea to counter this made up idea, but if you’re putting it on armor - a 12 gauge turret sounds so much easier. Doesn’t need a shitload of power, can put it onto a generic stand/turret base, targeting is easier and you’re guaranteed to ruin the enemy drone’s life
