The man who invented water as fuel died suddenly in a restaurant?

Stanley Meyer - An american inventor who first invented the water fueled car. Although it was allegedly spread that after he demonstrated his "Water Fuel Cell" in Japan, his invention was found false and his philosophy was wrong. Although this information was spread out to public, numerous of car and fuel related investors wanted to privately speak with Stanley.

March 20, 1998 - Stanley Meyer suddenly died at a restaurant with his brother. It was said that his brother claimed that during a meeting with two Belgian investors in a restaurant, Stanley suddenly ran outside saying - "They poisoned me."

According to Stanley's brother - "He took a sip of cranberry juice. Then he grabbed his neck, bolted out the door, dropped to his knees and vomited violently." I ran outside and asked him - "What's wrong?" Then my brother recalled - "They poisoned me. That was his dying declaration."

Although it was rumored that an inventor in Japan from where Stanley demonstrated argued that his philosophy was wrong. In 2008, Japanese company called Genepax revealed their water powered car in Osaka, Japan. It was said that Japanese inventors actually believed that it is possible to make water as a fuel. It was only a staged drama to lead the public to think lightly of this controversial invention. It was rumored that private investors didn't want  his invention to come out.

It was not just Genepax which released this water fuel car but also a lot of other companies from around the world. The story about this amazing invention didn't stop and in fact it inspired some of other inventors throughout the world. None of them succeeded and some of them just suddenly disappeared too.

Is there really a conspiracy? Was he supposed to die because he was a threat to the booming industry of "machinery".

It could also be that he just died naturally and thinking his invention was a risk to his life. He was anxious about it and thought he was poisoned.
