The problem with sloppy work is that the supply FAR EXCEEDS the demand

Then I went to check this "Wesleyan University" and in their website they present themselves as:
"Wesleyan University, founded in 1831, is a diverse, energetic liberal arts community where critical thinking and practical idealism go hand in hand".
I'm not fully acquainted with the US higher education nomenclature, but does Liberal Arts include Physics, Maths and Science in general?
RE: Could steam-powered cars decrease the CO2 in the atmosphere?
A degree in liberal arts prepares you to teach liberal arts to others.

The other problem is the water pump was attached to the rear axle, so to pump fresh water into it, one would need to jack up the rear of the car and run the drive to pump the water.
See video's with J Leno racing his steemer.
That said, at one time, coal plants used fireless steam engines to ferry around coal cars. They got there steam from the power plant it self. Just fill it up every few hours.
RE: Could steam-powered cars decrease the CO2 in the atmosphere?
I enjoy steam cars but no, I don’t see work being gained except by the media and shills.
RE: Could steam-powered cars decrease the CO2 in the atmosphere?
The same argument is true for electric vehicles. Where does the energy come from to charge the batteries? The power grid (assuming the grid can handle to additional demand).
Where does the energy from the power grid come from? Nuclear, coal, natural gas, solar?
The EV folks promote battery powered cars like a magical, environmentally friendly replacement for gas powered cars.
Granted, it may be cleaner depending on the energy source used to charge the batteries.
But the energy has to come from somewhere. Thats the dirty little secret that is not talked about.
Just because you don't see pollution coming out of the tailpipe, doesn't mean that pollution is not being produced to power cars.
Its just produced earlier in the supply chain.
RE: Could steam-powered cars decrease the CO2 in the atmosphere?
The author of the article acknowledges this. The combustion is a constant process, so burning can be more efficient. There is still CO2 pollution. I recall being told in college that very large steam turbines, i.e., ones that don't fit in cars, are very efficient. I wonder how efficient automobile sized turbines are.

To get NH4, one would likely need to produce CO2, but that is a different issue.
A solar car could, in theory, use solar panels to charge it. Not likely to happen.
We could burn hydrogen to create steam, but most H2 comes from electric production, or fossil fuels.
We can run a car/truck on wood using a otto cycle engine. But that would involve gasifying some of the wood to produce the fuel for the otto cycle engine.
EPRI had a paper years ago on whole tree burning to produce electricity. Still not been tried.

RE: Could steam-powered cars decrease the CO2 in the atmosphere?
All true ... BUT ... figure out the "well to wheels" efficiency. Or the "well to wheels" CO2 emissions, if you wish.
Even if the grid source is 100% natural gas, that can be a modern combined-cycle plant with a gas-to-electricity efficiency in the 50% - 60% range, and the efficiency of getting that electricity to your house is very high, and the charge-discharge efficiency of good modern batteries is also high (85% - 90%) and the powertrain efficiency is high. And the vehicle can have regenerative braking; no can do with a conventional pure combustion-engine vehicle.
Compare that to a petrol engine installed in the vehicle that has at best 30%-ish thermal efficiency and which spends most of its time operating "off design" at conditions having lower efficiency and sometimes zero (idling), and which is using a fuel that inherently has higher CO2 emissions relative to its energy content compared to natural gas, and which involves a refining process that is certainly not 100% efficient just as the grid-distribution of electricity from the central plant to the vehicle is not 100% efficient.
The situation is worse if coal is the grid-source ... there is a push to reduce the use of coal for electricity generation (and the province that I live in has stopped completely).
But the situation is better of the grid power is renewable.
If we, collectively, reduce the CO2 intensity of grid power generation by getting away from coal and towards renewables then the "wheel to wells" CO2 emissions of the EVs fed by that grid automatically shifts with it. The combustion-engine vehicle is stuck with using petrol or diesel for its lifetime ... Yes biofuels, but there's not much hope for that at this point.
And NO, nobody claims that switching all transportation to EVs is a magic solution to all of our problems. Doesn't address traffic congestion, for example. Taking steps forward is better than standing still or moving backwards.
The energy-consumption meter in my Chevrolet Bolt is hovering around 12-and-change kWh per 100 km, and it's functionally equivalent to a combustion-engine vehicle that uses probably 6 - 7 or at best 5 - 6 litres per 100 km, and the local grid CO2 intensity is roughly 25 grams per kWh (no coal, mostly nuclear, some hydro and renewables, rest is natural gas).

Can I get them in custom colors? Can I jack up the rear end? Can I tow a trailer? What If I need extra lift?
Do they come as contervatables? Can I get a moonroof?
