Hydrogen Reactor car
Dingel says he began working on his hydrogen reactor in 1969, and claims to have used the device to power his 1996 Toyota Corolla. Dingel explains that his invention splits producing hydrogen from water in an onboard water tank and does not produce any carbon emissions. However, he has never revealed the secret to his invention. In an interview with the Philippine Daily Inquirer, Dingel said that he would willing to reveal the secret of his invention if the buyer would hire 200 Filipinos and their families.
Dingel is known as a vocal critic of Filipino government officials and scientists who have refused to support his invention. The Philippines' Department of Science and Technology, in turn, has since declared his invention "a hoax." 
Investment by Formosa Plastics Group and Estafa case
In November 2000, John Ding Young of Formosa Plastics Group (FPG) sought Dingel out and, convinced that the invention was genuine, signed a “preliminary understanding” with him for several projects. He aims to have business partners to get an "international patent" and to commercialize his technology.
In December 2008, Dingel became even more controversial when he was found guilty and sentenced to a maximum of 20 years imprisonment in an Estafa (swindling) case filed against him by Young and FPG. In a decision dated Dec. 9, 2008 Judge Rolando How of the Parañaque City Regional Trial Court’s Branch 257 found him guilty of taking $410,000 from FPG, saying that Dingel "defrauded Young when the inventor failed to fulfill his obligation of developing his “hydrogen reactor” and creating experimental cars in 2000." 
Young claimed that Dingel signed a joint venture agreement with FPG, and initially received $30,000 in goodwill money and $20,000 for research and development. Young said that Dingel then visited the FPG headquarters in Taipei and asked for $300,000 so he could purchase three cars which he would use as prototypes when he returned to the Philippines. Young adds that in September 2001 he sent another $60,000 in additional funds, as agreed upon in the joint venture agreement.
Daniel Dingel died on October 18, 2010 in Las Pinas City, Metro Manila in the Philippines.
