Glenn Old is out to prove to the world that water and fuel really does mix together, reports The Sydney Morning Herald.

For six months, the Mackay man has been working with a group of American engineers to design, master and perfect a hybrid fuel cell device that could save motorists money and help reduce greenhouse gases.

“We have developed our HHO generator with safety first, designing a unit that produces enough hydrogen to safely gain up to 60 per cent increase in fuel economy and up to 30 per cent reduction in carbon emissions,” Mr Old said.

“We have gained national display rights to our product. Our purpose is to reduce the public dependency on foreign oil and we believe on a large scale with our device we will be able to remove smog from our capital cities within five years.
