HHO 4LPM Gas Generator
- Months of work: June 2009
- Approximate Build Time: 3 Weeks
- Max Voltage: 75V
- Max Stored Energy: ~0.1MJ
This project was to build a high-output hydrogen and oxygen gas generator by building a multi-plate electrolytic cell. This cell has 36 plates and runs best at roughly 65 volts DC. This provides 1.8V per plate which is the most efficient voltage for electrolysis. By putting the plates in series, this is much easier to manage than a single electrode electrolysis system, which would require immense currents at 2V. When it is run at 70 volts it is capable of up to 4 liters per minute of gas output.
When voltage is applied to the plates, oxygen and hydrogen gas are split apart from the H2O water molecules. When the gases are ignited, the only biproduct is water as the two gases recombine. The gas was fed into a torch head and can be used to melt anything, even rocks or the hardest metals.
This was built pre-MIT, and thus my machine shop consisted of a dremel and hand drill. This was the most painful machining I ever did, clocking in at more than 40 hours of continuous dremel cutting of stainless steel plating. More than 150 cutoff discs lost their life.
