I know your point. But certain things in the physical world are absolute: there is no cold lower than absolute zero (-259 C); you cannot send a space ship faster than the speed of light, ca $3,000,000 m/sec; Preachers and priests argued that invisible germs cannot cause disease--only a god can make you sick; humans cannot fly by flapping their arms.... No perpetual motion machine is possible.
I am sympathetic for pe3ople who iwiwsh to explorte aqndf find new things. I am enormously distrustful of people who make outlandish claims, usually for fun and profitm and fame. And it hurts me thqatn so many unknowledgeable people are taken iin, often to their finasncial hurt.
There is no gizmo for $49.95 that will make your car run on water (not even a hybrid).. or give you 100 mpg (altho much supressed).
Your point about trains is really only true for the USA. Europeans, Chinese, Japanese, Koreans make trains that go faster than 200 mph, 360 kph. Even 450 kph and remain on their rails (whereas US trains routinely fall off their rails even at 60 mph). So you cannot advance an idea that only applies to a subgroup addicted to cowcatchers and cowboys (it was James Watt (1736-1819) in England that made steam power.)
I give the authors credit for acknowledging the Chlorine issue. They admit they don't know what to do about it either.
There are only 4 Four Forces in nature, in the Universe;
1. the Gravitational force;
2. The Electromagnetic force;
3. The Strong nuclear force;
4. The Weak nuclear force.
The EM force is responsible for all atoms, all sound and light, all life, all biology, all mechanical and electrical matters, all matter--for sure, and most energy--burning, hydro, refrigerations, ..
If you are skeptical of my skepticism about 'hydrogen', just ask yourself:
Do catalysts violate conservation of energy?
You may find this informative:

II read they liberated "1 kg of hydrogen". Does anyone grasp how much volume that is at STP? It would take over a house and before it mixes with Oxygen and blows up, reverting mostly to H2O and some H2O2.
I will not discuss the E-cat, cold fusion, scams and delusions here.
