There's a really simple toy boat that uses a coil of copper tubing heated
by a candle to propel itself, and you can make HHO gas by splitting the
hydrogen and oxygen in water apart by running a direct current thru it.
You can try both by putting a candle and copper wire coil on a toy boat
and
running a 9 volt battery thru a cup of salt water. So the idea is to
burn that collected hydrogen and oxygen together to heat the copper
coil instead of the candle.

You'd do far better to run an electric motor from the 9V battery directly, but + for the remembrance of Putt Putt Boats! |
|
| |
How long would you have to run the 9V battery electrolysis plant to produce enough HHO for a single pop? |
|
| |
Still, + for uneccassery and complex modification to a beautifully simple design. |

I was given a putt putt boat six months ago and it's still sitting on my shelf. I suspect now is the time to fire up and introduce it to the kids. |

Make sure it hasn't seized up, or it will be a putt putt, bang boat |
|

Think of the volume of fuel in a candle compared to a comparable volume of hydrogen. I think the hydrogen will not make things very hot. |

Because of this idea, when I was in an auto parts store in Los Angeles today to buy car wax I actually found myself looking around at small coils of copper tubing for thermostatic controls and thinking, "I could totally make a putt-putt outboard motorboat with this!" |

Thanks for the brief return to childhood, [silentman]. |
