BTW, you certainly can use burlap to make computers. The circuit
boards are usually phenolic which is a canvas, or other fabric,
impregnated with resin.
Circuit boards are actually made of glass fibre mat impregnated with synthetic
resin. No burlap involved.
Thank you for your statement of the obvious. Please note that I used
the word "can", as in "are able", I am unsure why this mutated to "are"
in your mind. I will attempt to simplify what I thought was a clear
comment.
- Phenolic is comprised of resins and a fabric or paper core.
Fiberglas, or glass fibre, mat is a fabric.
- Not all printed circuit boards, PCBs, are made with fiberglass. The
less expensive ones are made with paper
- Here's an overview of phenolic laminates and the substrates used:

- The substrates can be paper, vegetable or mineral fiber or fabric.
Fiberglas can be considered a mineral fiber and it is certainly a
fabric.
- Burlap is a common name for a coarse fabric made from Jute, Jute is a
Bast Fiber, akin to linen (from flax).
- If paper, linen and canvas can be used for a phenolic laminate and
PCBs, so can burlap.

And, as noted above, that's not true. There are also other areas in a
computer where burlap (Cnoklin's choice of an impossible computer
material, BTW, not mine) and other substitute materials could be used.
The operative word being could, or can. Should they be used? Maybe,
maybe not. That depends on the specifics and economics of the
materials. But this is all totally immaterial.
I'm sure you are as aware of the attempted diversion from the topic at
hand as I am. An earlier paragraph in my original response was more to
the point:
"If the energy is essentially provided free, why does the initial
efficiency matter? So what if they can get 85% of the energy out of
oil, and only 30% (or whatever) out of the earth. It'd still be
cheaper, pollute less, and there'd be little need to traffic in energy
between continents."
I suppose I should not be surprised that someone with sparse factual
information, a stupefyingly rigid mindset and a lot to say, wouldn't
address the meat of the comment and instead poke at the potatos.
