nice bag of hot cheetos in the background.
you still go through energy drinks like water?
What about orbital laser canons?

Yes, there are some maser arrays, some nuclear pumped x-ray lasers, but most importantly there are plans for mirrors.
Lots and lots of mirrors.
So, near earth space - 1366 watts of energy per square meter.
Get a few dozen square kilometers of reflective surface, focus the output on a collimator, and you've got a point source of light with several gigawatts of energy output.
(Note, one square kilometer of energy at earth distance from the sun is 1366000000 watts, that is, 1.366 gigawatts)
Find a rocky/metallic asteroid, small (only a kilometer or two in diameter), slowly heat it up, capturing any gaseous vapours if you want. Using your Large Array of mirrors, vaporize parts of it off (this uses the material of the asteroid itself as a reaction rocket) to get it rotating slowly enough that it will not fly apart once it becomes molten.
Once it's molten, let it settle for long enough that the elements will differentiate based on their density.
The spin of the asteroid will let you peel it like an orange using the LAM to 'cut' it up by vaporizing thin channels into it. As this stream of material is peeled away, it is chopped up before it gets long enough that it starts to undulate wildly, potentially flying away on a trajectory that would be costly in delta-v to recover. These strips are then collected and left to cool, processed, or kept molten for further use.
The entire asteroid can be processed in this manner, giving very pure chunks of elements in large quantities.
The most immediately important thing about this processing is that you can now start producing mirrors in space, instead of lifting them from Earth.
Chunks of molten silicon are spun up/down until they are rotating in one plane, causing them to flow into a disc shape. With proper application of heating, the expansion into a flat disc can be controlled by manipulating the viscosity of the molten glass.
Once the disc has been gotten to the desired thickness/surface area, it is fused with a disc of aluminum to create a mirror.
Attach maneuvering packs, and you've got a big damn mirror.
Obviously, you can do other things, like let two or more blobs of pure elements mix to create near perfectly distributed alloys, make industrial quantities of amorphous metals, giant ruby lenses, etc.
Also to be noted, moving the mirrors closer to the sun gets you more watts per square meter, so you can throw mirrors that have near perfect reflectance deep into the well. (Any inefficiency in reflectance means the mirror will heat up, this is not a good thing and is why many will have active cooling systems)
1366 watts at Earth's orbit, 63,000,000 watts at the Sun's surface. And as you add more and more stages, you'll have to have even more insane collimation designs, as when you get to measuring the throughput energies in petawatts, shit's fucking crazy.
Seriously, earth's total solar energy input is about 174 petawatts. Lots and lots of energy being thrown around at this point.
Shit Ish you gotta be at least 18 or 19 years old by now...
I'd like to die with the songs I love stuck in my head. I hope to make the most of these hollow bones we become.
I raise a toast to the the souls that sang all along. I've been gathering friends to just to make some sounds,
before the ship goes down, I've been making amends by making the rounds before the whole world ends

i am such a little kid =O
...little ishie is 20!?
Dannnnnnng. I remember you when you were jailbait :O
wait wait wait...I thought i was way older than you. how is this possible????
I love Steal! <3
