Steam car

Transport and new transport: energy, pollution, engine innovations, concept car, hybrid vehicles, prototypes, pollution control, emission standards, tax. not individual transport modes: transport, organization, carsharing or carpooling. Transport without or with less oil.

Just think for two seconds: where does the energy come from to produce the steam?

I haven't read everything, but we know how to store heat
thermal solar is more than 2000 ° C
so fill up with steam, then heat a coil with a fluid and a reflector with a celestial drift motor with gps. it would be possible! To power a turbine, it can certainly work for some applications in a desert country
but it seems very complicated when it would be enough to produce juice in a power plant


And what does seriously serious GPS do?

Do you intend to move the reflector or orient it?

the subject here is not solar but the steam car

gps is for those who find the path of the sun too complicated to understand ... so you need at least a computer to calculate and a gps to give the exact coordinate necessary for the calculation

it's been a century since all astronomers have known the equatorial mount! and with a single engine running at 1 turn per 24 hours we easily follow the sun without calculation

what determines the efficiency of a heat engine is the temperature of the thermal cycle ... that the sun can do 2000 is useless for an ordinary steam boiler at 250 ° C ... it also allows to operate a superheater at 500 ° C as in the best coal-fired power plant, but this is the maximum possible with steam

with a diesel engine, we have a temperature of 1800 ° C without problem of materials because this temperature does not last long

Chatelot Hi!

Any good satellite calculator will give the exact position like this:

http://www.satcalculator.net/

But we have several solar trackers by searching the site much simpler without a computer or complicated electronics.


End of HS!

In the 80s a company (I no longer know the name) had studied and produced prototype steam cars.
power and vibration was not the problem
thermal issue on the piston less than explosion engine autan ddiesel than petrol 9 often no external cooling of the engine.
Benefits
It is use of many fuels.
accumulation of power to make it available on a small engine action on each stroke of the piston.
The disadvantages s
Complex operation for a car.
Use of problem water in cold regions
Voluminous boiler despite the new flat tubes, medium pressure operation.
Complex condenser to realize
Poor thermal efficiency
the use of a turbine instead of the piston does not improve the efficiency (the same thing with a jet turbine A

243km / h with a machine made only for a record, it's very sad

in the same article they give the previous record of a stanley which made 204 km / h in 1906!

do only 40km / h more 100 years later shows that we stumble on the limit

stanley made good diesel cars at a time when gasoline engines still had many faults ... already in 1906 the steam had lost the battle of energy efficiency, but the steam kept an advantage of reliability: when gasoline engines did not want to start personally could not do anything, the steam engine was ready to start, it had to wait for it to heat up but its operation was perfectly on

main problem of the stanley, it did not have a condenser, so like the steam locomotive it consumed more water than fuel ... it was therefore only usable in countries where we find water everywhere

as in the case of the locomotive adding a condenser is too heavy and has never been really profitable ... it is only on boats and fixed engines that the condenser is the right solution

there was still the besler plane cited by andré, which was a real feat in 1930 ... with condenser

André also makes us discover a besler steam car!

For the record, the first aeronautical engine in the world (Clément Ader) was steam.

It is not proven. Even a more powerful and lighter engine could not remedy an aerodynamic design that was not compatible with sufficient maneuverability to face rough aerology.

There is indeed a solar plane going around the world.
That doesn't mean it's the best concept for flying
so yeah, we can fly with a steam plane, we can
