50 years ago, an inventor introduced the first water engine. He was Spanish, a visionary and a complete fraud

“Of my patent, the license for Spain is transferred free of charge to the State for the benefit of all Spaniards.” Loud and clear, this is what Arturo Estévez Varela, the inventor of the water engine and, without a doubt, a great Spaniard. At least that’s what they must have thought. NODE viewerswhich in the early years of the 1970s included the words of this man from Extremadura. “That died with my father and we haven’t bothered to move it either,” said Arturo Estévez Jr. in a report for RTVE in 2009. Perhaps due to lack of knowledge or, probably, due to having too much knowledge. Knowledge that the invention, in reality, was completely unrealizable and that the patents shown to the journalist from the public entity have no value. But who was that man in a suit who drank from a jug before filling the tank of a motorcycle with water and made it work? Behind the name of Arturo Estévez Varela there was an inventor, an enormous visionary and, why not say it, also a scammer. Before his water engine, this Extremadura native born in Valle de la Serena (a small town of just over 1,000 inhabitants in the province of Badajoz) had already devised a chicken roaster with infrared and the “wing plane”, a device that allowed rockets to be recovered. Space X in Franco’s Spain. Arturo Estévez Varela in a demonstration of his invention With four liters of water, 900 kilometers of autonomy But if Arturo, who perhaps at this point we should start calling Don Arturo, became famous for something, it was for his water engine. An invention that, according to what he said, allowed you to travel by car 900 kilometers with just four liters of water. Statements included in the press of the time. It was October 1970 and, evidently, it seemed like magic. How did good old Don Arturo get a motorcycle he was taking around Spain running? Yes, with water, but also with hydrogen. Water was only one of the pillars of his invention. The third was hydrogen. And the second, a mystery. Town to town and city to city, Don Arturo traveled throughout Spain, generating a stir as he went, capturing the attention of the press and, as we have seen, also of the NODO. What this Extremaduran inventor did not reveal was what was hidden in that substance that, together with water, allowed the combustion engine of his motorcycle to work. In theory, the water reacted with a mineral that Arturo did not want to reveal. This reaction produced hydrogen which, when burned in the combustion engine, made the motorcycle work. That is, the procedure was similar to that have tried in Toyota. It is not a motor fuel cellis a combustion engine that burns hydrogen, a much more inefficient process. If we consult different sources on the Internet, many agree that the Francoism came to order a technical report to check if what that unknown inventor said was true. Obviously, everything was left in water, yes, but borage. missing These same sources end their story at the same point. Don Arturo was tireless in making himself heard, in convincing people and strangers that his invention worked and that it was the solution to many of Spain’s problems. However, it disappears. Nothing else was heard of him and the fables begin. Since the Franco regime tried to hide the invention until the oil companies decided to silence it. It seems that the secret, however, was not so secret. In this blog They recover a large part of press clippings from the time. Shortly after making himself known and without being listened to by the Government, Don Arturo managed to get someone to trust him. That someone was José Carrera Rey, a businessman who bought half of the rights to the invention at a price of six million pesetas. It is at that moment that Don Arturo loses track of him. José Carrera Rey then discovers that he has in his hands an invention that is useless. What it doesn’t have are six million pesetas and he doesn’t have a partner either. In desperation he denounces Don Arturo but nothing is heard from Don Arturo again. Only an indictment, in 1974, for an alleged crime of fraud, managed to get Don Arturo to appear in court. However, in December 1977 the magistrates were clear: Justice matters were already going very slowly in Spain and Don Arturo had not committed any crime of fraud because he believed in his invention, so there was no type of deception. Due to the dates on which the Spanish Television report was recorded and what his son says, Don Arturo died on the border of the 80s and 90s and took his secret to the grave. A secret which, according to the scientists who have studied the case, was boron. He boron It is a chemical element that, in reaction with water, produces hydrogen that, even, can become inflamed due to the enormous heat released. Hence, Don Arturo always warned that his “secret mineral” and water had to be mixed in controlled quantities. As collected The Vanguard last summer, the water engine, therefore, is perfectly functionalbut very little useful. To obtain 5 kg of hydrogen, with which a fuel cell Toyota Mirai (more efficient than burning hydrogen) travels about 600 kilometers, 45 liters of water and 19 kg of boron are needed. The problem is, basically, the 68,000 euros that 19 kg of boron would cost, according to what was reported in the Catalan newspaper. Was it functional? Of course, but, at its side, the first liter of synthetic and emissions-neutral fuel at 2,800 euros It no longer seems so expensive to us.

Jeff Bezos’ grandfather had the key to finding a job in the age of AI: being an inventor

With saturated selection processes (or directly broken) and the AI conditioning skills that companies demand, there is a skill that Jeff Bezos considers irreplaceable: the ability to invent. The millionaire value this skill above traditional knowledge or experience. Bezos considers that inventiveness is vital to maintaining creativity and innovation in modern companies, ensuring that he himself has applied it to bring Amazon and Blue Origin to their current situation. Lessons from his grandfather. In an interview During the Italian Tech Week 2025 conference that took place in Turin, the millionaire commented that his grandfather was capable of solving any problem on his Texas ranch by himself, without depending on outside help. “He bought a bulldozer for about $5,000 because it was completely broken. We spent a whole summer fixing it. To remove the transmission, we had to build our own crane. And that’s why he had an incredible ability to adapt. He believed he could solve any problem. And I watched him,” Bezos said during his interview. “He did veterinary work with the cattle. He made the needles himself. He took a small piece of wire and heated it with a blowtorch, flattened it, sharpened it and made a small hole in it. Some cows even survived,” he commented sarcastically. That ability to adapt and create practical solutions taught him the value of inventiveness in facing difficulties, a lesson that Bezos has also applied in his life and in the management of Amazon. The “inventor” of Amazon. Bezos himself defines himself as an inventor, stating that “it is his fundamental nature. Put me in front of a white board and I can generate a hundred ideas in half an hour.” The founder of Amazon looks for those creative skills in his team members. In an interview In 2012 at the Utah Technology Council, Bezos indicated that “when I interview candidates, I ask them to give me an example of something they have invented.” Obviously the millionaire was not referring to a patent, but to a process, an idea or a solution to a problem that existed and for which he imagined a solution. “You have to select people who like to invent, think innovatively,” said the millionaire. Innovation as an antidote to fear. One of the six fears that have defined Jeff Bezos’ career is the fear of garages. Not in the literal sense of the place but of the symbolic sense of innovation that they have acquired: HP was born in a garage, just like Apple. “Two kids in a garage scare me more than the competitors I already know,” assured Bezos in an interview. The inventive capacity is a lever towards innovation and experimentation, which has been one of the pillars of the business culture that has taken Amazon to where it is today. “Someone who comes to Amazon and doesn’t like pioneering, doesn’t like exploring, doesn’t like going down dead ends that often turn out to be dead ends, will leave soon,” Bezos said in his interview. In his job interviews, Bezos asks: “How can we do A and B? What invention do we need to bring the two together?” That is, value those candidates who do not see the options in black and white, but rather look for new ways to combine and improve processes to innovate. AI has accelerated everything. More and more CEOs and senior officials at large technology companies agree that they are the skills and attitudes, and not the knowledgewhich will make candidates stand out in the age of AI. The current CEO of Amazon, Andy Jassy, ​​pointed out that knowledge can be acquired over time, but what companies need in this era of constant innovation are people who know how to adapt to any circumstance and learn from it. “The biggest difference between the people I started with in the early stages of my career and what they are doing now has to do with how good they were at learning.” According to Jassy, ​​the attitude and talent to innovate It has to come standard.
