HYDROGEN MOTORBIKE (Next level?)

[graucho]

About how much would a conversion cost, if you were to do the installation yourself? I still think it's worth looking into. Do you make it ONboard or do you charge the tank at home?

The only tank is the water/fuel cell design. And a flashback bubbler. When you turn on your key, production starts. Turn off key, production stops instantly. No storage tank. Its up to you to come up with the ultimate fuel cell design. Thats what we are all competing for. Ill give you some youtube videos to get you started. Everything you need to know to get you started is here. People are posting from the beginner, to the advanced level. If you dont want to make one they sell them of ebay. But you wont learn squat unless you do it yourself. I cant go backwards and start over, im at the level of the last video. If your going to do one and hit a snag, im here for ya.
Here ya go. Good luck.

If you keep the hydrogen separate from the oxygen until it hits the intake manifold, then, while the hydrogen may be a bit more likely than gasoline to ignite, it's manageable.

BUT, if you mix the H2 and the O2 right in then tank itself, THEN you're asking for trouble. The gases are mixed, and are already at the optimum stoichiometric ratio - it truly is a bomb waiting to happen. You should really separate the O2 and the H2 generation chambers, and pipe the two gases separately to the engine.

Gasoline is much less flamable than H2 to begin with, and when you mix the fuel and the oxidizer before you actually need to, you're asking for trouble.

I'll post this one last time. If the system process is using a battery to electrolyze hydrogen & oxygen gas, and then burn the gases in an internal combustion engine, then it is impossible, under absolutely any circumstance, for this process to be more efficient than just using the battery to directly feed a high efficiency electric motor. In fact, using an internal combustion engine, the process efficiency will be, at most, about half of the electric motor efficiency. And, it CAN'T be otherwise, as it would violate the laws of thermodynamics. Any believe otherwise is wishful thinking.

graucho, if you want to waste time on this, go ahead. I know that you've spent a great deal of time already. But, as a system, onboard H2 generation is too inefficient to ever, repeat, <ever> make this system process more efficient than a decent electric motor system.

 

[graucho]

Totally understood. Your correct about efficiency. All along ive never said anything about being efficient. Ive only stated the fact that soon im not going to use gasoline to get where I want to go.
Im going to my sink for tap water, filling up my hydrogen fuel cell , charging up my battery, and giving the gas station the finger as I drive past. Not the most efficient way of transportation on earth, but no gasoline. End of story for me.

Any full time MBc member with more than 300 posts who wants to learn about hydrogen fuel cell technology PM me and ill start you on your education.

Graucho. Do you have pics of your fuel cell? Maybe you would rather not,huh.

Efficiency or not,fact remains. You are running on fuel you produced yourself.

 

[loquin]

And, what I'm getting at is this. If you want to use a battery to power the system, just hook it to a decent electric motor & drivetrain, and still "thumb your nose" at the gasoline-using riders/drivers. Not only does this approach free you from the pump, it will take you further than hydrogen will, and it's more quiet and less polluting than an IC engine, which will burn small amounts of oil (from the crankcase) as it runs.

If you want to use an internal combustion motor, then set up a larger electrolysis unit at home, add solar cells to produce hydrogen for free during the day, and use power from the grid at night, if needed. Add a pair of small compressors to bottle up the H2 and the O2, and use that on the road.

By building a larger electrolysis facility, it can be made more efficient than you could possibly do on a portable unit. Producing more fuel than you otherwise could, and possibly avoiding the grid altogether.

 

[Large Filipino]

That's it. OMG. Solar cells yes you need a lot but you can in theory have your solar cells on the roof of your house. They make cells now that actually look and act like roofing shingles. Then have it all set up with a Home compressor sized tank (the big one) to take in the hydrogen with the pressure gauge to see how much hydrogen you have then you could fill up your little tank or tanks daily and have some in reserve.
Now that beats electric for your taking the energy from the sun.
The sun.
Water.
Brilliant.

The other advantage of a pressurized tank is this - as you drop the pressure to get the H2 & O2 to atmospheric pressure for the engine, it provides a source of cold. Add a small cooler around it, and voila! Frosty beverages!

 

[Large Filipino]

That's hitting many birds with one stone!

In the spirit of alternative fuels,it seems the talk of microwave energy does have merit.
Remember in the movie "Back To The Future" in the end of part 3 I believe the professor finds garbage to be used as fuel for his Delorean? Well check this out:
