This project aims at providing electricity while still being minimal in size and maximal in generating power. Compact HHO Turbine or CHT, this turbine uses hot expanding gases to run a turbine and produce electricity.
The CHT electrolyzes water and uses the by-products as fuel. The turbine has discs as a rotor which are closely spaced and thin. The high-speed spinning of a magnetic material (the discs) in the presence of magnets produces electricity.
In order to tweak the settings to get the desirable amount of voltage or current, there are some sensors. This sensory data is displayed on a TFT LCD screen as well as on a monitoring webpage hosted by the microcontroller.
The complete apparatus includes an electrolyzing unit, a gas chamber, an impeller, a spark plug, a rotor, a stator, some magnets, an exhaust and an iron-carbon battery.


The power consumption by the human beings is at its peak and so are the CO2 emissions, more and more people are moving towards green power and trying to contribute as much as they can to reduce the CO2 emissions. Well, the CHT aims to do both.

To explain it all in short, water is poured in the electrolyzing unit, the switch is turned on, the water in the unit starts to break down into hydrogen and oxygen which then come together to form HHO, this HHO travels through a one-way check valve into the gas chamber, from the gas chamber the impeller sucks it and pushes it to the spark plug, here the gas ignites and expands rapidly to produce thrust in the direction it was pushed, this is where the rotors kick in, the rotors make use of this thrust to spin at a very high speed. These rotors are magnetic, so it attracts and repels the magnets in the enclosure simultaneously, thus producing electricity. That was as condensed as it could be. Now, let's dive deeper into the science behind it.

The Electrolyzing Unit:

The water in the electrolyzing unit doesn't necessarily need to be from a fresh source. It will work even if it was directly from the sea, the salt will act as an electrolyte, but if the water was fresh and right out of the tap, Potassium Hydroxide (KOH) is used as an electrolyte, while it is not a necessity, KOH can also be put in salty water. KOH is losing its ions to water, as its dissolved, but is left completely untouched in the whole reaction, these ions help to conduct more electricity, which means more HHO produced and lesser power used by the electrolyzing unit. When electricity is passed through this unit, around 4V, the water breaks down into Hydrogen and Oxygen, these evolve as a gas, HHO. This HHO then travels to the gas chamber.

The Gas Chamber:

Simply put, it is a chamber that stores gas. But, there is also a bit of science behind it. The chamber is cylindrical, and the path the HHO takes from the electrolyzing unit to the gas chamber has a one-way check valve, this valve helps to stop the gas from going back to the electrolyzing unit.

The gas chamber is not very intricate geometry-wise as a cylinder is more than enough for the storage of any fluid. Let's have a look at the next part of the process, the Impeller.

The Impeller:

The more the gas is compressed, the better and this is exactly what the impeller is for. The impeller is built up around a low voltage, low current, high RPM brushed DC motor.

Besides compressing the gas, the impeller also gives a little push to the expanding gases in the direction which they need to go.

If it weren't there, the ignition of the gas would ignite the other HHO in the gas chamber, which is not really appropriate. Thus, in a way, the impeller is also acting as a one-way check valve.

    The project has got hold of a considerable amount of views. I didn't expect any, really. But, to update the awesome people who have looked at this project, the laptop had some issues whilst downloading Windows 11, maybe I did something wrong, but now I've rolled back to Windows 10 and this is working fine. I put together some ideas on paper, but had to redo everything from the ground up if I foresaw a probable fault. I have tried to settle upon one design, but I haven't been able to. I will redo stuff in Fusion 360 and make a zero version of it, carry out some tests, improve and the best version, I will put up here. 

    Have a great day!

    Updated project details and pictures of the ongoing build coming soon!

    The whole apparatus is built from Acrylic, Graphoil (or Grafoil or graphite foil) and some 3D printed parts. Plus other complementary parts, such as nuts & bolts, connectors etcetera.

    The details for the project are almost done!

    I am late on publishing the details as I submitted the project just a day before the deadline and I was a bit busy with all the high-school exams and stuff in this week.

    So, I will submit the details as soon as possible and then I will start designing the turbine in CAD.

    I have got some rough sketches but it will have to be turned into CAD, so...

    And this turbine will hopefully be complete before the end of this month.

    So, excited and terrified, both at the same time!

It's a dry cell type of HHO Generator.

  Are you sure? yes | no
