Höyryautoja
Höyryautoja
Tyttären kanssa leikittiin tänään vanhalla höyrykoneella ja surffailin myös netistä höyrykoneasiaa. Sattumalta löytyi myös seuraavanlaista:

As a result of the 1973 oil crisis, SAAB started a project in 1974 headed by Dr. Ove Platell which made a prototype steam-powered car. It used an electronically-controlled 28 pound multi-parallel-circuit steam generator with 1 millimetre bore tubing and 16 gph firing rate which was intended to produce 160 horsepower, and was about the same size as a standard car battery. Lengthy start-up times were circumvented by a system using compressed air that was stored when the car was running and which powered the car upon starting until adequate steam pressure was built up. The engine used a conical rotary valve made from pure boron nitride. To conserve water, a hermetically sealed water system was used.

You have the most convenient and knowledgable consultant right there in Sweden. Dr. Ove Platell, at platell@ranotor.se He was the head of the SAAB steam car project, and when he retired he got the remains of that car. I believe he still has it.
SAAB tried a conical rotary valve made from pure boron nitride.
Their steam generator was a mulit parallel circuit design that was carried to such an extreme that any obstruction would have caused burnout. However, that design can be modified to be more acceptable.

But now SAAB, the Swedish car and aircraft manufacturer, has come up with a steam engine that looks like a winner. It will have 250 HP, yet it weighs less and takes up less space than a conventional car engine plus radiator and transmission. The boiler consists of some 120 parallel discs of fine, spirally wound tubing. Liquid fuel (such as gasoline) is burned in the spaces between tubes, turning the water in the tubes into steam. This steam generator measures about 4 by 12 inches and weighs about 26 Ibs. The condenser is air cooled and not radically different trom a conventional radiator.

Periaatteessa jatkuvalla palamisella saataisiin hallittu palotapahtuma ja ekopipertäjät tyytyväisiksi. Jos laitteista ei tule paljoa lisää painoa autoon ja hyötysuhde kohdalleen. tehokkaan polton kautta hyötysuhde voisi kasvaa tavalliseen polttomoottoriin nähden. Vesi sitoo energiaa jota ei juuri sillä hetkellä tarvita. painetta voisi ohjata helpostikin. Onhan paineilma autojakin olemassa. Sitten on taas eriasia, mitä vehkeet painaa, kun pitää olla vettä (ellei miller moottori ja suljettu järjestelmä? sekoitanko ideaa?) ja polttoainetta sekä molempiin omat laitteensa. yms hyötysuhteet. Polttoaineestahan energia kuitenkin tulee ettei maksimi tehoa voi saada paremmaksi, ainoastaan hyötysuhdetta kasvattaa ehkä? (näin ilmeisesti saatukin tehtyä kun aika hyviä tuloksia esitetty) Jännä, että saab tässä mukana.

Sitten alkaisi viripajat kauppaamaan "erikoisrikastettua" uraania ja tosi HC-tu(u)nareille plutoniumia.

Niin ja mitä uskotte, tulisiko ajamisesta noin yleensä varovaisempaa..Olli Kinaret kirjoitti:Kylmillä keleillä joutuisi käyttämään rikastinta.Svc kirjoitti:Tai sitten minikokoinen ydinreaktori keittämään vettä höyrykoneelle.![]()

Täältä näkisi ainakin hyvin kun kaupungissa ajettaisiin kolaria, nousisi heti pieni sienipilvi.

Höyryllä tai yleensäkin paineella toimivassa moottoritekniikassa luulisi olevan myös helpompaa esim. vedon jakaminen ja tasaaminen 2 tai 4 pyörään kun mitään mekaanista ei tarvittaisi vaan kaikki toimii pneumatiikan tyylisesti. Moottorit saattaisi olla mahdollista jopa integroida pyöriin niin ettei mitään erillisiä vetoakseleita tarvittaisi. Myös jarrutustehon talteenotto luulisi olevan helposti mahdolista. Polttoaineeksi kävisi monenlaiset palavat nesteet ja niiden laatuvaatimukset eivät olisi erityisen tiukat.
