CAR AND BOAT TO STEAM

AUTOVAPOR.jpg (137246 bytes)

This it is a simple car that really works with the steam that is generated in a boiler, as in the antiquity the trains to steam did it. He is very simple to construct, takes control of materales discarded as soda water tins. In the photo down one of these ready cars can be seen to work.

This car is so simple to construct that it a boy can do of 10 years advanced. Since sharp tools are used and the tins in if they cut easily it is good for having the supervision of an adult.


What is a Steam engine

A steam engine is a mechanical device that turns the energy of the aqueous vapour into mechanical energy and that has several applications in propulsion and generation of electricity. The basic principle of the steam engine is the transformation of the calorific energy of the aqueous vapour in mechanical energy, causing that the steam expands and it cools off in a cylinder equipped with a movable piston. The steam used in the generation of energy or for heating usually takes place within a boiler. The simplest boiler is a closed deposit that it contains water and that is warmed up with a flame until the water becomes saturated steam.  The efficiency of the steam motors is low generally.



Steam turbine of Herón

HISTORY

The first mention of the idea to use steam to obtain energy appears in the pneumatic one, of the inventor and Greek mathematician Herón de Alejandría, in century I. described his eolípila There, a steam turbine that consisted of a boiler connected by means of two tubes to the poles of a hollow sphere that could turn freely. The sphere was equipped with two fuzes bevelled by where it left steam that produced the rotation of the sphere. Have been other references in works of the average age and the Renaissance, but it does not seem that practical devices have been constructed until the architect and Italian inventor Giovanni Branca designed a boiler that expelled steam, which pushed some trowels that excelled of a wheel, doing to turn it.

The first steam engine, constructed by the English engineer Thomas Savery in 1698, consisted of two copper containers that filled alternatively of the steam of a boiler. The machine of Savery was used to extract water of the mines, as the developed one in 1705 by the British inventor Thomas Newcomen.



Our turbine of Herón you sewed of a soda water tin as boiler that rests in a doubled quadrangular tin in three. Latita of metal is warmed up underneath with an alcohol burner done of one (for medicines, etc). Soprte of the wick is tubito of metal or I could and be ahcer tubito from a tin piece. Upon the boiler a rotor is placed done of tubitos of plastic (tubes of puntabola, ball-point pens, etc) placed to the sides of a piece in T for aireadores of aquariums.

THE TRAINING OF THE STEAM

When the water is warmed up gradually, the temperature is increased. When it arrives the boiling point that is of 100 degrees Celsius to the sea level begins to form steam bubbles. The temperature continues growing. The heat that is continued increasing is called “latent heat? or “vaporization heat? and does not leak hottest but it is used to turn the liquid into gas.

It is very important to notice that the steam expands 1 more 700 times than the water in liquid state. Meaning that it occupies a greater space 1 700 times. The steam inside the boiler tries to save, sui is an opening will leave that way with much force, but there is no exit is possible that an explosion takes place.

Down a steam turbine done of a discarded center is seen.


Down a boat can be seen steam with trowels constructed from the car.
