"Run your car on water". "Clean the air as you drive'. "Do it yourself, it's cheap and easy". More than likely, you‘ve heard these claims discussed in conversations, posted on the web, or seen them in magazine ads. if not, let Diesel Power be the first to tell you that yes, water has the potential to help power your diesel vehicle. The question becomes: is hydrogen for you, and at what cost?	If engines were more efficient, HHO wouldn't be needed in order to burn the primary fuel more completely. Remember, only about one third of the fuel you bum and convert into heat actually goes to powering the wheels, the rest is dissipated by the cooling system and exhaust. A good cell produces 3 liters of HHO gas a minute, which is still only enough hydrogen to mn a lawn mower. This being the case, hydrogen-on demand systems do not fuel the vehicle, instead the hydrogen is thought to speed up the combustion process. According to the guys at Hydrogen Hybrid Fuel Cell Corporation, as a rule of thumb, a hydrogen producing cell needs to produce half a liter per minute of H2 gas for each liter of displacement your diesel engine has.
HYDROGEN BASICS	INCREASING EFFICIENCY
Hydrogen is the lightest. simplest (contains only one proton), most abundant gas in the universe. It is the fuel of choice for our sun, so calling hydrogen an alternative energy source is a stretch. In the 1860s and 1870s, some of the first automobiles were powered by hydrogen, since gasoline was considered too dangerous. During World War I and II, fuel shortages drove engineers to create hydrogen-powered vehicles. Today, major automobile manufacturers are building hydrogen fuel cell cars, which consume stored hydrogen gas (l-I2) in a fuel cell in order to produce electricity for an electric motor. But, there are a few challenges with using stored H2 as a fuel.	An acid. base. or salt can be added to the cell's water supply in order to drop the electrical resistance ofthe water. With a catalyst in the water, it takes fewer amps of electricity to produce the desired amount of HHO gas, since the ions in the water are able to move more freely. Potassium hydroxide (KOH) is a base and a popular catalyst for HHO-producing cells. it is important to make sure the catalyst you're using isn‘t highly concentrated, because it could damage your intercooler. This is an important aspect where more research is needed. Keep in mind. a properly designed cell will not need large doses of electrolyte. Varying amounts are added to the mixture in order to tune the on board·hydrogen system. Heat, pressure and electromagnetic fields are also employed to help break down the water. although this technology is not very mainstream.
First of all, hydrogen gas is not energy-dense by volume, so a hydrogen fuel tank has to be huge, or it has to store hydrogen under extremely high pressure (70,000 psi) in order to be as energy-dense as diesel fuel. According to a Department of Transportation report titled. "Guidelines For Use of Hydrogen Fuel in Commercial Vehicles: Final Report} 'Gaseous hydrogen fuel with the same amount of energy as one gallon of diesel fuel would only weigh about one third as much, but would occupy almost seven times the volume if stored at 10,000 psi. Second, there is no hydrogen infrastructure to fuel hydrogen—powered vehicles. While there are more than 70.000 diesel fuel stations across the country, there are less than 70 places in North America to buy hydrogen for automobiles. Commercially made hydrogen is produced by stripping the carbon atoms out of compressed natural gas (CNG) using steam. This process, known as cracking. converts CNG, which has a chemical formula of CH4, into hydrogen gas. So, unless one gets their energy to make hydrogen gas from wind, solar or geothermal sources, they might as well just skip a step and bum the CNG.	Alberto Aschidamini and his son have a website called www.hydrogensolutionsondemand.com, where they sell different products. His call uses an electromagnetic field and nitrogen from the air to make large amounts of HHp gas. This type of cell is called an Australian cell.
MAKING HYDROGEN FROM WATER
Electrolysis is the scientific word describing what happens when electricity breaks the molecular bonds that hold water together. At the atomic leveL water contains two atoms of hydrogen and one atom of oxygen. when two volts of electricity are passed through water. hydrogen bubbles form on the negative side of the circuit (cathode) and oxygen bubbles appear at the positive side of the circuit (anode}. Hydrogen does not like to be alone, so it joins with oxygen right as it leaves the cell. This new gas is called oxyhydrogen (HHO). In the automotive world, the terms oxyhydrogen (HHO) and hydrogen are often used interchangeably, even though they are not technically the same thing.	This dry-cell unit produced by Energybuilders.net Is a very advanced design. Whereas a wet cell has the different electrodes submerged in a container of water, this setup; has the water come to it. Each cell (A) can use up to 40 amps of electricity (C) and produce 3.5 liters of HHO gas per minute (D). The bubbler/water reservoir (I) serves two purposes-it holds extra water and is designed to stop a flashback from going all the way back to the cell.
HYDROGEN-0N-DEMAND
The systems we are talking about in this article use the hydrogen-on demand approach versus a high-pressure hydrogen-storage scheme. A hydrogen-on-demand system stores hydrogen gas compactly and safely as water until it is needed. One gallon of water equals about 1,800 gallons of HHO gas-this means you don't need a lot of water to make a lot of hydrogen. In most kits. the electricity used to power the cell that converts water into hydrogen comes from the vehicle's alternator and batteries.
DOES IT REALLY WORK?
Skeptics argue that the energy needed to separate water into hydrogen equals (or exceeds) the energy given off by burning HHO in the engine. There is also concern that enthusiasts and companies looking to sell hydrogen conversion kits oversimplify the process and do not take into account the advanced tuning needed to see results (especially with computer controlled diesel vehicles). A quick search on Wikipedia nets different results depending on how you word it. For example, type in "water-fueled car" and it will say it doesn't work. Type in 'hydrogen fuel enhancement' and the prospects brighten. The truth is. your results will depend on the efficiency. of the HHO cell generator you use, and the efficiency of your engine
