In other words, yours is 8 times as expensive to run.
If you have a battery the best way to transfer the power within to motion is by using an electric motor and motor controller. The efficiency of that is typically way above 50%.
The thought you would have a big battery on board and just use that to make a diesel engine tick over goes against logic. Like if in the time of the first real cars you'd build a mechanical horse to pull carts instead. |
You're looking at it from an energy-efficiency perspective.
This project idea was never about energy-efficiency.
Instead, I was looking at it considering these design criteria:
* the fuel needs to be usable in a Diesel engine
* the fuel should (when burned) not emit any carbon or toxic gases
* conversion needs to be relatively cheap to do
Regarding the cost, I don't agree. I agree the fuel costs would be higher, but if you look at the whole thing (so including conversion costs), it would be cheaper -electric motor, battery and motor controller tend to cost a lot-.

I did know about the negative perspective most people have on HHO. What I did never read anywhere however were scientifically based arguments (so including energy calculations, ...). That's why I made the post and did the calculations. What I actually found was that it was a much better fuel than I initially thought. Seifrob and ar5boosted mentioned alternatives like compressed air and steam I could use. Well, compared to that I think HHO is a better energy carrier (if it wasn't for the damage it inflicts on the engine, but for say overbuild Wankels -found in construction equipment-, this might not be the case)
Anyway, it doesn't matter any more as despite meeting my initial criteria, it does damage regular Diesel engines. So it's useless.
A more interesting question to ask now however is: is hydrogen usable in Diesel engines (so not gasoline engines, but Diesel engines) ? If not, what's the reason why it doesn't work in them, and are there any workarounds to fix that problem (like using fuel or combustion chamber pre-heating, adding of a spark-plug inside the combustion chamber, ...) ?
If I find that I can just use hydrogen in Diesel engines, then that would even be better than if I were able to use HHO.
