What if I connect it to my own brain, will it eat my soul out, bit by bit?
You can't connect a kinamp to your brain, at least not as it is right now. I don't know if that is even possible, since kinamps work in a very specific way. There's a very small chance that you can, but that would require some research.
What you
can do is implant yourself with a psychokinetic amplifier and modify your brain to allow activating the psychokinetic amplifier in a certain way at the push of a button, thus imitating a kinetic amplifier without the need for a battery, but that would probably be a bit harmful for you. Plus, since your brain would need to be used to run math calculations, you'd eventually start getting tired and run the risk of an overload if you tried something very hard.
There's actually a procedure that can convert you into a psychokinetic amplifier "god", but it leaves you completely paralysed, strips you of your free will and imagination, severely damages your body and brain to the point you need to be constantly connected to a life support device and has a high chance of killing you. Plus, it still does not remove the limits of your willpower, it just pushes them further, so you can still get tired and you can still cause an overload.
http://einsteinianroulette.wikia.com/wiki/NPC#Amp_SpecialistYou need to find a human "volunteer" that would be available so that you can have his brain transformed into a weapon. And you can't just create a copy of his brain either, because the psychokinetic amplifier somehow understands that the brain is copied. You'd either need a steady stream of people willing to essentially have their brain converted into a weapon or some sort of farm where humans are raised and then slaughtered like cattle. So it's possible, but a bit expensive (not to mention morally questionable) and would take some time to do properly, since humans are a bit hard to find at the moment. We should build some flying saucers and start abducting people...
Is it time to start a cult? I think it's time to start a cult. If that UE could do it, why not ARM?
Join the cult of Steve the Savior. You can have Steve's eternal love. You just have to accept him and let him save you from the burden of your brain and all the problems it creates. He'll make sure to put it to good use and give you a purpose, turn it into a weapon with its pleasure centres locked on "max".
EDIT: Oh, and bluerad is a non-rechargeable crystalline battery with an incredible energy density. It essentially allows you to power giant machines with very small batteries, at the cost that you can't simply recharge the batteries, you actually have to create new ones. And it's highly radioactive, so large batteries (larger than a basketball) need shielding to be used by humans safely. On the other hand, batteries of that size could run a laser for weeks.
Are we restricted in quantities of that resource? Or it can be reproduced?
It can be reproduced. You just need enough energy to create it. However, once it is created, it cannot grow further.
Nobody has asked about how exactly the crystals are grown, so I cannot tell you how exactly it works. But I assume it's an expensive and complicated process.
