HODINFO is a collaborative think tank/ open science initiative. We are an International group comprised of inventors, scientist, mechanics, tinkerers, fabricators, and out of the box thinkers. Our mission is to find innovative solutions to the problems that primarily limit the production and delivery of H2. As the world starts using hydrogen it becomes clear that immense infrastructure initiatives will be required to make it happen. If adequate solutions can be found to support Hydrogen-On-Demand (HOD) systems then the world can remove great and costly limitations on future applications. The future is not just Hydrogen, it's Hydrogen-on-Demand.

Measurements of temperature and electron density of oxyhydrogen (HHO) flame

Here is a paper by a Swiss researcher named Slobodan Stankovic.   click here Chris Eckman, another HHO researcher in Idaho,  USA estimated HHO flame temperature to be 130 deg. C based on infra-red imaging.  I have always been a bit sceptical of that calculation.  It might be based on the assumption that the camera is pointed at a "black body".  Black body radiation is completely different from the infra-red / visible radiation coming from a flame. However, this study uses a different method but gets roughly the same result.  Haven't had a chance to look at it carefully but it looks interesting.

Hello everyone. The calculation of the temperature of the HHO plasma (as it is one) is based on the electron density, as described in the article. Obviously there is no much of free electrons in the plasma, that's why the temperature is very low, between 130 and 150°C.

I would like to do a monograph on this topic.   I have a copy of papers done by Meidanshahi et al and a review by Shakher and Nirala.  Thinking of starting with the basic background and developing that into your conclusions in a way that is understandable to anyone with basic knowledge who is willing to put forth a bit of effort.  I have several monographs on my website  hho-research.org. 

But I would like to redo these as pdf's with a more designed layout and a color scheme using a Latex template and Lyx environment.

Also interested in flame emission spectrophotometry of an HHO torch.  I have a used monochromator and a photomultiplier tube with a socket module that supplies high voltage. The photomultiplier is almost too sensitive.  Even with voltage turned way down, sensitivity is 10 amps / lumen.  But max. anode current is 0.1 mA or 100 uA.  So sensitivity is also 10,000,000 uA/lumen.  If I have an op amp with 1 Kohm feedback resistor, it gives 1 mV per uA,  which would be about 1 analog-to-digital converter count.  So 1 ADC count would equal about 1E-07 lumens. The amplitude of the spectrograph plot might need a bit of logarithmic scaling and use of 10 stop neutral density filters to attenuate incoming light.  Three filters in tandem would attenuate light 1,000,000 times. (0.01 x 0.01 x 0.01 = 1 E-06). If voltage is turned up,  the sensitivity can go up to 10,000 amps per lumen.
