Where Are You Going To Get Fuel For Your Hydrogen Car ? Are Hybrid Cars Really The Solution ?
I saw a comment to an article I was reading about BMW and a hydrogen car they were supposedly going to market next year. The person asked why we didn’t have a full-on hydrogen car in the US. I guess my question is: where are you going to get fuel? The infrastructure for hydrogen, as a stand alone system, is beyond the horizon. We should be looking for alternatives, in fact we should have started doing that in the 1970’s with the first energy crisis. Hydrogen, even small amounts, increases the efficiency of other fuels. Most automotive hydrogen is produced by splitting hydrogen and oxygen from a water source that includes a catalyst. The overall gain, from working with various systems of that type, is 5% to 8%. Any gain is good, but that’s a long ways from stand alone.
The key is efficiency, which brings us to other items that aren’t as difficult to obtain, like octane. A simplified explanation follows. The higher the octane, the more efficient the combustion. The slower the burn, to a certain point, the higher the octane. Water vapor slows the burn and increases octane. On a foggy day there is a higher percentage of water vapor in the air, increasing horsepower. The horsepower increase on a foggy day is due to increased efficiency which is due in a round about way to the octane increase. When octane is increased, the timing can be advanced, which contributes to an earlier spark and the opportunity for a longer burn.
Computerized cars, after 1996, have OBDll, and later, compliant computers. Computers, if matched to the right system, will due all the changes. You don’t have to advance and retard the timing or rejet the carburetor for different altitudes and conditions because the computer does that for you. With the right system you don’t have to do anything to the computer. The computer sensors monitor the exhaust and lean the mixture if the engine is running cool enough. 60% to 80% of the fuel that goes into the engine is used to cool internal parts. Water is about 200 times more efficient at cooling than gasoline or diesel.
I was watching a NASCAR race and one of the commentators made the statement that “all the horsepower is in the camshaft and cylinder head(s).” That statement, in the way it was worded, in not correct. A large percentage of the horsepower is in the camshaft and cylinder head(s), but not all. There’s a reason the fuel they burn is rated at 99 octane. The slower the burn, the more complete the combustion.
A engine has to “breathe” to be efficient. Like the human body, if the airways are fouled or restricted, the human body and the engine aren’t capable of reaching maximum efficiency. Water vapor steam cleans internal engine parts. It breaks carbon off the valves and pistons and flushes it out the exhaust while cleaning the exhaust system in the process. If water vapor is introduced at the right place in the intake system, it cleans the passages, mixes with the fuel and increases octane. Higher efficiency results in more HP and better fuel economy.
Going back to hydrogen, there is a hydrogen producing system that’s as close to free energy as you can get. It seems to make sense to use what’s already available, as opposed to wasting it and expending other energy to produce more. A high priced, high tech vehicle isn’t necessary. But, to make everything work at the optimum, you need to have all the information and not just one piece of the puzzle.
