Device developer Sumit Isarangkul na Ayutthaya, managing director of Pathum Thanibased Integrated Technology Consultant Co Ltd, and codeveloper Somchai Traisuriyathamma presented a hydropowered car at a press conference hosted by Udon Thani Rajabhat University's Mechanical Engineering Department.

The conference did not reveal the cost of invention or its commercial use.

Sumit said the reactor - a 12inch wide and 10inch high metal box installed inside the car's trunk - used electricity to extract two atoms of hydrogen and one atom of oxygen from water. It needed direct current (DC) from a 12voltage battery to extract hydrogen for the car engine's combustion, he said.

This device extracted hydrogen for each use without having to store the gas in a tank, Sumit said.

He said the "Reactor 1" could also control the heat produced from the hydrogen extraction to a safe level.

The result was clean energy.

Sumit said he continued to improve on the safety of the "Reactor 2" model by designing an electrical circuit to detect any abnormality in the whole system.

The circuit would work with a "Micro Controller" to control the reactor and the engine to save the battery and have just the right amount of hydrogen produced for the car's engine usage.

"I'm very happy to serve my country and there are many things to do. This invention is not my first and certainly will not my last. There will be more and better inventions to come," he said urging the Thai public to give support to his team.
