>>489279>lol, are you an MIC marketer?If you knew what effective directed energy weapons will likely look like, you might not be so quick to jump to that conclusion.
Lets begin, directed energy weapons will have some energy conversion losses, that means waste-heat. Small things are better at shedding waste-heat than big things, because small things have more surface for a given volume.
That means that if we are going to make a energy weapon, it will be made from an array of many tiny emitters, that all aim that the same target.
This thing will not be cannon-shaped. It will be a large flat emitter grid.
It's going to be practicle to install it next to a population center, being the size of a very large parking lot and then hook it up to the power-grid to charge a capacitor-bank that will provide the insane peak-power requirements.
It's not suitable as a offensive weapon, because you can't realistically stick this thing onto a "mobile attack platform".
But wait there is more, you'll need a gazillion emitters, so it's going to be made from mass produced components. So it won't be super secret military tech, and hence no big profit margins, which translates to zero interests from defense contractors.
I think the pioneer effort to build this will come from civilian space agencies looking for a means to clear space trash that's interfering with their launches. Said space trash will become a major thing because off all the satellite constellations (each containing many tens of thousands of sats) that are going up.
Big cities will be next to adopt this, they will see it as an energy shield, probably against unwanted drones, to be more attractive than "unprotected cities". They'll basically just copy paste what space agencies created and tweak it a bit. And then it'll be infrastructure.
If enough of these get build, they can be synced up and used to snipe nukes.
