Alternative Technologies: The Power Of

The verdict is in. After two popular on the inner workings of the transmission, it is that TTAC loves articles about complicated devices. Always one to try to get into the of the latest fad, I thought maybe I too could use my own hard won knowledge to write an informative

The problem is that the only I really know how to work on technology that is seldom in cars these days:

Many people think the of steam power has come and but the truth is that it is still us. It’s true that the locomotives that once across our great land, pounding wildly as they themselves along the rails at that often exceeded 100 have all but disappeared, but the reasons for demise have little to do the efficiency of their power

No, the steam locomotive was undone by the that most of them one-off creations, each one of required specially constructed and that, when General finally began to apply the of standardized parts and the production to the creation of diesel engines, the beasts were finally to extinction. No, steam simply to places where it could be to its best advantage and where it works with such that it is utterly unremarkable.

The power of steam comes its expansion. To people accustomed to about the automobile, the way steam can easily be compared to the combustion of which takes power a liquid fuel, gasoline or and then ignites it into a gas forces a piston to travel in a power ….

In the case of power, water is heated pressure in a boiler until it to vapor and is taken from the via a series of pipes, scrubbed of its and sometimes superheated, before released through a nozzle or valve into an area it can fully expand. That can be used to cause a piston to through its … or a turbine to Of course, this is a simplistic but just to give you an idea of the available, just understand water expands into at a rate of 1700 to 1, meaning one square foot of water to 366 degrees F at 150psi will to 1700 feet of water at Zero psi.

The big, high marine power plants I to work with were systems. The boilers themselves several stories high, had a big enough for several people to around in and thousands of water tubes leading into an steam and water drum.

The steam and water drum several pieces of equipment, several that were to dry the steam so that water could not move through the and impact sensitive parts and a superheater to give the steam one burst of energy prior to its into a high pressure turbine. Once the steam had through its initial expansion in the HP it would then flow a low pressure turbine where it the rest of its energy and then into a condenser, basically a big to condense the steam back water. That water was pumped back up to a preheater brought it back up to temperature so it be re-injected back into the

For the most part, boiler is recovered by the system and never allowed to cool much the boiling point. Once the is up and running the energy demands are not outrageous considering the amount of generated and the good news is the boiler will run on the worst of fuel so long as it is liquid to inject into the firebox and well enough to make

Of course, a ship’s engine has a lot of other things going on to the process I’ve just Some parts of the steam are off to run the high speed, high feed pumps required to the feed water into the at the beginning of the process and still is taken to run other systems the fuel heating systems and the that ships use to turn sea into fresh water. The is a space crammed full of and a maze of pipes, many of that are hot enough to burn you through your boiler should you happen to brush up them in the wrong place.

The and water cycle of a steam engine is much the same as I have described above for the turbine. Water is heated in the run through the pipes and recovered in the of condensate the exact same The difference is the where it is allowed to and how the energy is drawn from it, time into a piston than a turbine.

Most piston engines are two strokes, that they only power and exhaust strokes the gas being used does not and induction or compression …. is released into the chamber it expands and forces the piston to the of the ….

The exhaust … is completed by live steam on the bottom of the through a second set of intake and forcing it back to the top of its …, in is called a “double action.” The to this system is that time the piston moves it is power. That power is put to the propshaft or the locomotive’s wheels by a in much the same way it would be a gas or diesel engine. The exhausted is then recaptured in the form of and then reintroduced to the boiler it can repeat the process.

The most application of the steam engine to the world is the Stanley Steamer. vehicle, which was for a time the in the world, utilized a simple and a steam piston engine featured two cylinders. Produced in sizes for almost 25 years the was a great success.

The engines rated by their steaming at 10, 20 and 30 horsepower but had they been at their actual numbers at their cranks the 20 hp variant have produced a solid 125

it is easy today to look at the Stanley Steamer as some of quaint attempt to marry the developing modern age with the era, the truth is that were well built, powered cars that well regarded in their The technology was and is solid and, it not for the lengthy start-up times due to the to bring the boiler up to temperature in to initiate the process, I think it still do well on the road

In the years since the Stanley left the road and steam left the rails, marine powerplants continued to develop and of the problems that the early faced were eventually by technology. Things like feedwater controls, devices ensure the boiler water over or under filled, and relief valves, valves activate in emergencies to release and prevent boiler explosions, made the highest pressure safe and easy to use and it seems to me today, given the willingness of to plug their car into a socket, that the steam car make a quick comeback by electricity to maintain the boiler while the car isn’t in use.

almost a century after the car into the recognizable form it has taken today, the need for efficiency is driving new innovation. New of cars are being developed day and in our rush to embrace the alternative of future I think the potential of power deserves a second as a well. With so many new looking to capitalize on bygone perhaps one day soon we’ll a new version of the Stanley Steamer on the road.
