Our recent loop tests did not yield savings higher than 5%, which was not significant enough for these tests to be continued. All future tests will stop.

If anyone still think HHO works in converting existing vehicles to hydrogen hybrid, they have to convince us with more than 10% savings with loop test results. We still do not quite understand our non-loop test results, but we trust more our loop tests as they reduce most of the unpredictable factors that might affect the testing results.

We apologize if our non-loop test results had misled you in the past.

As we test various kinds of HHO generators, one single problem keeps popping up with all brute force electrolyzers (wet cells with the electrode assembly immersed in water) is the overheating of the cell – we discussed this problem here earlier:

As we mentioned at the above link, the only solution – without using a current-limiting electronic circuit – is to switch to the dry cell configuration. So we built one and installed it on our 2006 Dodge Sprinter cargo van. Here are pictures of the cell installed at the back of the passenger seat and the reservoir/bubbler used for the cell:

So we did some road tests with it and here is the most recent one that was done on April 14, 2009 for a trip to Edmonton. In order to make this test result comparable to the one we did on August 19, 2008 and reported here, we chose to keep the cell OFF for the trip from Calgary to Red Deer and then ON from Red Deer to Edmonton. The cell current was very steady (around 14A), unlike the wet cell design. For or curiocity and convenience, I chose to inject HHO before the air filter this time. The weather on that day was not good: icy snow all the way from Calgary to Edmonton with the temperature around zero degree. That explains why the fuel consumptions were quite high compared to those of Auguest 6 and 19 last year. As usual, we filled the tank to the rim on each fill-up. Anyway, here is the fresh and raw data, together with the last year’s August 19 result listed as well for comparison purposes:

We have tested quite a few HHO generators – whether commercial or home-built devices – all have the same big problem: OVERHEATING! Most can reach the boiling point within an hour of operation if the current is 10A or higher.

We have tried adding neutral plates, but it did not work well. At one time, I used seven (yes, 7) neutral plates and still the temperature reached to 80 degrees C in an hour in a cell made from a black PVC pipe. The commercial SL50 device we bought works better as it has a casing made of stainless steel which makes the heat dissipate better than PVC or any other non-metal materials. But still it becomes very hot. The temperature outside the casing is measured around 50 degrees C – we taped the temperature probe to the SS casing – the inside temperature must be at least 60 degrees.

Using square-wave or pulse to power the HHO cell does not work too well because the critical issue is that the cell is enclosed and heat does not get dissipated easily from the cell even though the power cuts by 50% or lower using pulse.

Anyway, after trying many things including testing various commercial devices, we have made one conclusion…

All the enclosed cells where the electrode assembly is submerged in electrolyte – let us call them “wet cells” – have this overheating problem. And the problem can go out of control as higher the temperature is, higher the current will become, which in return will drive temperature even higher. Making the casing with stainless steel can minimize the problem but will not eliminate it completely – and it is just too expensive to make the casing all with stainless steel. What is the solution then? Continue reading “Problem of Overheating for HHO Generators” »

If you know about Stan Meyer and his water-powered dune buggy, you will know that his buggy car went missing shortly after he died on March 21, 1998. Now I just learned that Stan Meyer’s long-lost dune buggy car has been found!!!

Boy,as a registered user of WaterFuelCell.org, I have not checked their website for a long time. Today I went there and you know what? I found this exploding news that was posted there on Aug 12, 2008. For those who are also interested in Stan Meyer and his dune buggy, here is the link to the post:

Hmmm… Stan Meyer’s patents expired in the year 2007 and now we have found his dune buggy – not only the car but all the original patents, documents, demo cells, electronic circuits and devices are in the hands of the sole owner who is willing to sell.

For those who do not know the difference between Stan’s cell and the conventional water electrolysis cell, we say this: Stan’s cell does not use the conventional water electrolysis process which uses DC to break water molecules. Stan uses a gated pulse to do the job.

As the water in the cell does not contain any electrolyte. It can be the tap water or even distilled water. The current used is very small, smaller than 1 amp. So there is not much heating in the cell, not to say over-heating. As a result, he and some of earliest witnesses of his demo claimed that the cell remain COLD throughout the process – see this link:

Road tests are very time consuming and each test cannot be finished in one trip if the route is very long. And there is a lot of factors involved that could affect your test results: weather, fuel station/pump, driving speed, etc.

While carrying the road test, one question kept coming up: Is there a single test that could demonstrate if and how much a HHO generator can save fuel? Continue reading “The Crucial Test to See If HHO Generators Indeed Save Fuel” »
