What do you get when you combine water with a homemade electrolyzer and a car battery? BOOM!
In a previous project, I built a generator that uses electricity to convert water into a very powerful fuel. The amount of electricity available determines how much gas can be produced. I've got this hooked up to my car battery and have produced up to 5 liters per minute. I've even tried powering it with a makeshift hand-crank generator, but obviously the gas production is slower. So just how powerful is the gas? Watch the video to find out!
The gas is just a mixture of the H2O molecules broken down into their gaseous elements of two parts Hydrogen and one part Oxygen, which combine as H2 and O2 gas. This is sometimes called HHO, or Hydroxy gas. I used a bbq ignitor to see if the bubbles will pop.
Some people might ask what the purpose of the bubbler is. It helps clean the gas, but more importantly, it acts as a flame arrestor in the event of a flashback. The bubbler cap is just pressed on, so if there's a tiny flashback explosion, the worst thing that happens is the cap pops off. If the bubbler's a little low on fluid then be careful, because now the gas has a place to build up, and if you were to get a flashback in this situation, it could be a little more dramatic. It's helpful to keep the bubbler full, so I made mine detachable for ease of use.
