Yes, and how do you think they boiled the water to get steam? Huh? Any ideas? We're all waiting for you to let us know.
Oh, yeah, maybe they set something on FIRE, like GASOLINE or DIESEL FUEL or COAL or PROPANE.
Are you aware that when you set something on FIRE, the products of combustion are water, carbon dioxide, and some stuff left over? And that as long as what you are setting on FIRE contains carbon, that's the way it is.
(OK, OK, I know, you can burn sodium, or magnesium, but those are not realistic energy sources for a whole host of reasons.)
You can choose to burn hydrogen, and you won't have any CO2 waste product. But how exactly do you expect to obtain the H2? You can do it by electrolysis, which requires vast quantities of electricity, which is generated by BURNING STUFF usually (oil, coal, natural gas), or by nuclear reactions (and CO2 looks positively benign compared to the waste products of that!) or, to some extent, by hydroelectric or geothermal generation. Or, you can use those evil petroleum products, and strip the hydrogen out of them by chemical reactions, which I bet require all kinds of "interesting" catalysts and intermediate processes that you probably wouldn't like to see on your dinner table.
My first guess was coal, my 2nd guess was diesel and last one was propane
There is no such thing as "residential geothermal heating" except maybe in Iceland.
I know it's a heat pump but the industry commonly refers to it plainly as geothermal which of course leads to confusion as illustrated by Lucianao's post. Pick your argument with them.

What might be referred to here, is the use of the relatively constant temperature of the earth a few feet below the surface as the heat sink and source for residential heat pumps. When it's 100F outside and you're trying to reject heat from the condenser to that, a dozen feet below the surface it's something like 55F, which is a much better temperature to reject heat to. Similarly, when it's 25F outside and you're trying to gain heat from that to boil refrigerant in the evaporator, a dozen feet below the surface it's something like 55F, and it's a lot easier to get heat from that.
I'm well aware of how it works, I've even given a explanation on my residential heating calculator which I might add is one of the most popular in the world.
I was actually joking about the coal. It would be very unsuitable for this. Take too long to get going and there is no way to turn it off other than letting it burn out.

Fair enough
I am not saying steam cars have to be next thing shoved down "our throats" next, as if self driving cars don't already cause enough controversey
But I been wondering how the practicality could do in the modern world.
