Besides, again. The healing machine isn't some normal piece of hardware either. As for the manual being within reach. Remember we just escaped from a really bad fire. Chances are it would have burned.
as for the wires... You yanked it out from the wall so those need replaced. I highly doubt it has its own power supply. Reference the episode when Team Rocket cut the power to a Pokemon center and they needed Pikachu's electric to get it remotely back on. The machine itself was also down.
that said even after repairing the wires... Still need a power source.
Then the concepts of how it works would be documented somewhere in plenty of text books or research papers. The The majority of it though... basically -is- a machine.
He mentioned that it needs a power source, specifically enough power for an AC unit, which has a strong enough draw you need a very heavy cables, and a larger breaker tolerance. He's basically saying that you can't plug it into a normal outlet. A power supply is actually what transforms AC current (the electricity from the wall) to DC current. Those are -always- part of the machines. For larger machines, it's a replaceable box bolted into the machine, as it also doubles as a breaker for power surges. For smaller devices it's embedded. You know that box in the back of your computer where the power cable goes? The box inside of an xbox if you ever opened it up. The box for a monitor. This massive box that will kill you in a projector, and a box in the base of those robotic arms used for construction lines.
Also I wouldn't use that pokemon episode as a reference, especially as a source of reason. Pikachu can generate a lot of volts... but that's not what powers a machine. It's both volts and Amps. Yes, Pikachu can match a lightning's strike, but you can easily assume that it's far less than an AMP in current as it doesn't kill anything. This means the most he could really power is a few very weak lights... assuming he didn't blow the bulb.
But if you broke a 120volt lamp's light bulb, which is 80watts of power, you'd commit suicide by touching the diode.
A volt is the force used to move energy. Amp is the flow of that energy. If the energy doesn't flow, it's not doing much work, thus very little power. If the current is high, it's doing a lot of work, which gives it a lot of power.
Can we just move on? This is already spanning two pages >.<
