What People Say about Us

I've got my second Hydrogen system on my Nissen diesel and great savings as I travel through outback Australia selling my “fun fried chickens ” setup to roadhouses. My records show I'm saving 51% of fuel costs from before When I didn't have a Hydrogen system. This Hydrogen is the future of energy and fuel savings . And it got much more power and torque.


Cairns , Queensland

We set up the new Hydrogen fuel system Gen 15 on the new campervan and successfully ran the unit through Northwest up to Broome. We have the new gen 15 hydrogen system set up and running at 26 amp and using one liter of water every 13 hours. I am averaging 8.0 L per 100k when the vehicle is carrying 500kg of camping equipment, water food and fuel on the bush roads between the isolated gold mining Ghost towns of WA.


Western Australia

For 3 years I have successfully run my 1988 Unimog 435 Camper with an OM352A diesel and AV intercooler. It was fitted with a GEN 15 Knox system and delivered exceptional power, particularly in the mid-range torque, which required less gear changing in hilly terrain. My fuel consumption was also reduced, as a result I could manage 17-18 mpg on a long haul into the outback.

Just a quick review on my experience with your hydrogen fuel saver. I’ve only been using it for about a month on my 2010 V6 petrol Hilux. I noticed early on that I normally get about 500 km per tank of fuel. Not great. With the hydrogen unit, I am easily getting between 650-700 km per tank in the first month. Depending on the sort of driving I do as to the extent of the savings, there is a definite overall improvement in mileage. It’s nice to see that the fast-falling fuel gauge needle has finally slowed down! I am very happy with the results. They have easily hit my expectations. Thank you very much,

I bought a Gen 15 hydrogen fuel cell . I put it into my F250. I am getting 9 litres to the 100 km. I've doubled by economy and much more horsepower. This Unit is the future saving money. This is fantastic. Thank you for your invention. Im happy to speak to anyone who wants to know more about my hydrogen fuel systems.
