It ran on seventy per cent hydrogen peroxide, first developed as a fuel back in the 1940s for the pumps of the V2 rockets that tried to win the Second World War for Germany. When hydrogen peroxide comes in contact with a catalyst, such as permanganate of potash, it breaks down into oxygen and water. But the water is in the form of high-pressure steam, which is used in engines.
Maudslay that I was not an amateur, but a regular working engineer. With this object I set to work, and made with special care a most complete working model of a high-pressure engine. The cylinder was 2 inches diameter, and the stroke 6 inches. Every part of the engine, including the patterns, the castings, the forgings, were the results of my own individual handiwork.
Then followed a lecture on the duties and shortcomings of fathers, which lasted an hour, and left him shaking like a sick man, sprawled out in the big chair by the fire, and smoking like a high-pressure tug. But she had brought him around, and he had arisen to go out to the town's one jeweler, when she lost all she had won. "Where are you going?" she asked sharply, as he put on his hat.
Ballard, riding ahead of his posse, reined in his horse sharply at the head of the trail leading down to the stream as a shot crackled viciously in the depths of the cañon below. There was no mistaking that crisp, whip-like report of a small-calibered, high-pressure rifle cartridge, and he wondered much that it was not accompanied by the whine of the long metal-cased bullet about his ears.
Next the throttle is opened, without admitting sufficient steam to the turbine to cause the spindle to turn, and it is seen that the steam exhausts freely into the atmosphere, also that the high-pressure end of the turbine expands freely in its guides.
"So far from it, wherever the water has been laid on at high pressure, the waste, which is terrible now some say that in London one-third of the water is wasted begins to lessen; and both water and expense are saved. If you will only think, you will see one reason why. If a woman leaves a high-pressure tap running, she will flood her place and her neighbour's too.
This means that the total heat remains practically the same, no matter at what pressure. This is James Watt's discovery, and it led him to the use of high-pressure steam, used expansively.
You see it requires power to send out transmission waves and therefore to do it you have to employ a high-pressure current. Receiving, on the other hand, demands delicately adjusted instruments which are equipped to catch every faint, incoming wave. Should you let the strong charge of electricity used for transmission pass through your fragile receiving apparatus you would ruin it in no time."
Though the adoption of the steam-blast greatly quickened combustion and contributed to the rapid production of high-pressure steam, the limited amount of heating surface presented to the fire was still felt to be an obstacle to the complete success of the locomotive engine. Mr.
She derived this speed from six water-tube boilers, feeding at a pressure of three hundred pounds live steam to five turbine engines working three screws, one high-pressure turbine on the center shaft, and four low-pressure on the wing shafts. Besides these she possessed two "astern" turbines and two cruising turbines all four on the wing shafts.
