Is this true? That it'll kill an older car faster? If that's the case that may be why people aren't excited about it.

Glad to help. I have to point out, however, that CO2 is not a pollutant. It will be produced whenever carbon is oxidized, whether that oxidation is through combustion or life processes or chemical reactions. It also is necessary for plant life, which is necessary for animal life (including ours).
Hydrogen is indeed the only fuel we know of that does not contain carbon and therefore produces no carbon dioxide. However, hydrogen is unproven. By that I mean that I cannot just go down to the car dealer and purchase a hydrogen-powered car. Nor can I take such a car to a fueling station and fill the tanks if I were able to purchase one. Nor have I been able to actually built a hydrogen-powered engine yet. The videos you see on YouTube are typically scams, which use some hidden energy source to produce hydrogen from water through electrolysis. This does not produce energy, as it requires just as much energy to produce the hydrogen as one would get from burning it or using it in a fuel cell, if we assume 100% efficiency.
Tesla's 'free energy' wasn't free, if you are talking about the wireless transmission of power he is known for. The power could have been obtained for free by someone with a receiver, but the power was generated by more mundane means. There are plenty of theories floating around about how some of his other devices could be used to produce free energy, but so far no one has been able to demonstrate it.
So while I think hydrogen may someday be a great idea, and while I admire Tesla's work and his ingenuity, reality still says we have no present fuel source that is not carbon-based. If that changes, great. But until it does, we still need fuel.

With alcohol fuel, you can become energy-independent, reverse global warming, and survive Peak Oil in style. Alcohol fuel is "liquid sunshine" and can't be controlled by transnational corporations. You can produce alcohol for less than $1 a gallon, using a wide variety of plants and waste products, from algae to stale donuts. It's a much better fuel than gasoline, and you can use it in your car, right now. You can even use alcohol to generate electricity. Alcohol fuel production is ecologically sustainable, revitalizes farms and communities, and creates huge new opportunities for small-scale businesses. Its byproducts are clean and valuable.
Yes, you would need to change alot of things on your car, the fuel tank, the fuel flow system, the emission port and lots of parts that need to be upgraded. Though the engine you have and most of the things underthe hood would not need to be changed due to energy still being transfered.
I agree you do not get a 100% energy you get something like 65%. Still plenty enough to run a car, but incase it isn't you could always change a few things like adding solar panels to make up the other percentage. Or adding fuel cells or even more hydrogen generators. The more hydrogen created the more fuel. Theres even an addative you could put in water to add more hydrogen.
The emission ports are part of the internal engine. That's the valve train.
There is also the timing of the spark, the coolant system may need to be upgraded (I have not checked out the heat produced by such a system, so this is a maybe), and some thought would have to be given to corrosion by an excessive amount of water vapor (although I doubt this would prove to be a major problem with most engines).
In order to recycle the exhaust you would need an efficiency rating of over 100%. That is zero-point/over-unity, to achieve energy without adding energy. Also, anything you add to create additional hydrogen is adding energy, because you are inducing a chemical reaction to lower potential chemical energy. Whatever you add will also add to the cost of running the car.
