Electric HHO Boat - Is it Electric?

[eboat]

Thinking...

If I go with a Turbine, why not let it be a generator at the same time and feed back to the electrolyzer?

hmmmmmm.....

but how much energy will it take to run the generator and still have something left to move the boat ????

I'm glad you still have all of your fingers after playing with HHO around your tractor!

[Meniscus]

Correct me if I'm wrong, I'm thinking that if you create a electro magnet via coils around the turbine, then you would generate voltage. Basically the opposite of what we are used to thinking.

Sorry no picture depiction.

In case it is still unclear how the variable capacitor works or how much production is generated with this systems, check out this video:

To vary the gas output would it not be easier and less moving parts just to vary the amount of volts that gets put into gas generator ?
Thinking about the rc stuff just use an esc to vary the voltage to the motor(or generator)

[Meniscus]

My main concern is to ensure that there is no excess production, because...you know

I believe that there would be a lot of lag time if you did it with regulating the power. I'm sure that there is going to be around a one second delay or so already.


Well, I guess I'm looking for a turbine. Anyone have any experience with this or can make a recommendation? The closest experience I have to a turbine is either a ducted fan or a turbo on a car.

there are a lot of videos on youtube on hydros with turbines... there is one that is pretty fast...40's maybe... they are pretty big boats since the turbines that can generate enough power are a bit heftier.

[Meniscus]

I've viewed an few. Not being a plane guy, I don't have the experience with the turbines. Anyone care to chime in on a possible product or line that may serve my purposes?

Also, I completely understand that the boat wouldn't meet the guidelines to be raced. What does everyone think? Electric? Not?

Not electric
You might be using electric to produce your fuel BUT you will still be burning it some how in a combustion engine

[Meniscus]

Point noted.

Aw man, does that mean I have to take this thread elsewhere???

It is clean though, byproduct is H20

Fascinating idea, but there is a shortcoming. Energy you put into a system (your battery's charge) will always be more than energy out of that system (thrust) due to mechanical losses and heat. This is true for any system, since no one has ever built a 100% efficient machine.

So you take the battery's energy and create O2 and H2. Already you have some losses to heat and inefficiencies. Then you burn the O2 and H2 in a turbine (or a rocket motor). Again, you have some mechanical and heat losses. Then you have a gearbox for that 100,000 rpm turbine. More mechanical losses and heat.

I'm not saying it won't work; rather I am saying it will be a less efficient use of energy. You can never get more energy out of a system than you put in (unless you start splitting atoms, but that is another type of physics).

It seems that the most efficient use of stored electrical energy (your batteries) is to turn a brushless motor connected directly to a propeller. Some of those motors approach 95% efficiency.

Now if you want to mix some C-Stuff and T-Stuff (hydrogen peroxide and sodium permanganate) in a small reactor chamber using your electric motors to pump the two fluids, you may have something that goes really, REALLY, fast. Be careful though, it may be a bit more dangerous than your LiPos.

Ub Hauled, thanks for the links. It will take some time to review!

[Meniscus]

Dr. Jet,

I completely understand the losses. It is just an idea I had, not saying its good, but I haven't seen anyone else try, so I might as well try!

Now on your idea...please be careful throwing ideas out like that, the kids might be reading and no one wants that liability!!! LOL!

Intriguing concept, I may have to try. However, I am the first one to realize when I'm over my head and pushing my lips up to the surface right before I go down. On second thought, I think I'll have to leave that concept to someone else...I like all ten of my fingers, not to mention my nose!

[Meniscus]

OK, I'm not saying that it won't work, but I've done some calculations and it doesn't look good immediately.

I guess this project will have to be on hold until someone is willing to give up an old turbine! Meanwhile, I'm going to keep looking for some injectors that may be more feasible.

Thanks for the input everyone! If anyone knows anyone else doing this, LET ME KNOW! I'll share my experiences and maybe through collaboration, it can become a reality.
