The motor should he made to run at that speed at which it gives the greatest power with a high efficiency, without heating to a degree which would damage the insulating material. Before fixing a motor in its final position, it should also be tested for power with a dynamometer, and for this purpose a Prony brake answers very well.
Thus the prow was welded; armored, insulating air-breaks were built along the stern, which was the plane of hexan cleavage, electrical connections were restored; and lastly, a set of the great Vorkulian wall-screen generators, absorbers, and dissipators was installed, with sufficient accumulator capacity for their operation.
She could do no more, for the further end of the passage was plunged by this insulating flood of moonlight into inscrutable darkness. It was so quiet that she felt that she had missed him; he had already entered her room; but while she considered the awful indignity of surprising him there, the sound of a light tapping on the door's panel relieved her. She thanked God that she was still in time.
In it the current produced by the dynamo machine, fixed at a convenient station and driven by a steam engine or other motor, was conveyed to a dynamo placed upon the moving car, through a central rail supported upon insulating blocks of wood, the two working rails serving to convey the return current.
I assumed that these stockings worn among the other stockings we had on would have an insulating effect. Opinions were greatly divided on this point; but I must confess in common with my four companions on the Polar journey that I would never make a serious trip without them. They fulfilled all our expectations. The rime was deposited on them freely, and was easily brushed off.
The vapor of the abyss thickens; and a distant roll of thunder seems to come from its depths. The pythoness, seated on her tripod, rises slowly from it. She has discarded the insulating robe and veil in which she conversed with Napoleon, and is now draped and hooded in voluminous folds of a single piece of grey-white stuff.
Instead there were only weak, unsound huts, built with a framework of oddly shaped driftwood and covered with a thick layer of insulating sod. A road ran through the center of the city, only distinguishable because it was packed down by constant use, and on either side were groupings of the huts in semi-circular patterns, with no space between them left unfilled by soil.
Alas! it is a hard case with a man who lives upon his own bottom and responsibility, making himself no allies, sewing himself on to nobody's skirts, insulating himself, hard, when his trouble comes; and so poor Doctor Grimshawe was like to find it.
Normal insulation and printed circuitry wasn't designed to last for thousands of years. Each wired circuit would have to be removed, duplicated, and replaced. Every printed panel would have to be cleaned and receive a new coat of insulating varnish. Working full time, a four-man electronics team could do the job in a week. Working part-time the two of them might get it done in three months.
Having, apparently, made careful mental note of the rooms, Durkin once more turned back to the switchboard, and prying loose the fluted molding that concealed the lighting-wires, he scraped away the insulating tissue and severed the thread of copper with a sweep or two of his narrow file. He felt safer, in that enforced darkness, for the work which lay before him.
