We learn from Ed Harris that initially, the hosts were androids - mechanical robots made to look like humans. This is also seen in some flashback sequences, and Robert, the kid who opens his face to reveal the circuitry inside. In episode 6, we learn that the hosts were later switched to the current 3D-printing process, in order to appear even more human.

However, what exactly is their physiology? Their energy source? Do they need food or store it inside a stomach chamber? Or are they charged overnight, since obviously they do need a source of electrical power for remote control and data transmission?

  • So far it's not shown in the series, maybe you should watch to see what happens? Could be part of the mystery, maybe it will never be explained in the series... – Luciano Nov 15 '16 at 10:04
  • You should probably ask that second question separately, since it's unrelated to your first one. – KutuluMike Nov 17 '16 at 11:33

According to showrunner Jonathan Nolan this will be revealed in Season 2:

Can you say how are the hosts powered? Like do they need to recharge? Do they eat?

Their construction and their power source is something we’re really going to get into during season 2. So we’d like to keep that mysterious. 

<p>They’re closer to biological than they are to mechanical,
but they don’t suffer brain death the same way we do. They’re largely
indistinguishable from a human beings, but their brains don’t require
oxygen — which opens up interesting possibilities. Their brains are
not as fragile as ours. On one hand, their cognition is controllable
and malleable, but on a structural level they can’t be killed in the
same way you and I can. </p>

<p>There are advantages and disadvantages to
being a host. <strong>Season 2 we’ll be exploring more the nuts and bolts of
what they are— as the hosts themselves are trying to understand</strong>.</p>
