DIY Hydrogen/Oxygen Generators From Grocery Store Items (HHO Fuel Cells & Split Cell Electrolysis)

I had a lot of fun doing these experiments about 12 years ago.  I ended on some conclusions.  Straight DC is okay, but when you get to playing around with pulsed DC, you can really go crazy.  I ramped my voltage up to about 5KV and was able to adjust my frequency to about 1-2 kHz and able to adjust the duty cycle as I saw fit.  Last set of toying with it was to use pure water with no electrolyte, and having a resistance monitoring system to automatically adjust the duty cycle based on water quality.  And that's when I reached the end of my skill set.  I'll hit it back up when I learn to code.

It's Rocket Science! with Professor Chris Bishop

Starting with the one simple principle that has powered every rocket that's ever flown, Professor Chris Bishop launches through an explosive journey to the moon and back. 

This lecture from the Cambridge science festival is packed with demonstrations of the science that sends people into space. A family-filled lecture theatre sees flying projectiles, the fiery combustion of energetic propellants, and the impressive roar and flame of a hybrid rocket engine.

The Difference Between Gasoline And Hydrogen Engines

How hydrogen combustion engines work, versus gasoline engines. Hydrogen combustion engines can be more efficient and with better emissions versus gas engines, due to the fuel differences of H2.

This video will look at eight major differences between gasoline and hydrogen fuels used in internal combustion engines. This includes the combustion reaction and byproducts, air fuel ratio, ignition energy, flame velocity, auto-ignition temperature, diffusivity, quenching distance, and density. These properties result in drastic differences between using the two fuels, though both can easily be adopted and used in traditional otto-cycle piston cylinder engines, often with little modification to the existing engine hardware. Are hydrogen engines the future of internal combustion? Let's find out!
