Small bottles or capsules of water with hydrogen and oxygen, or air, dissolved in it under low pressure, when lose pressure -release hydrogen/oxygen bubbles which when ignited, cause the water to boil and create steam, which powers a steam engine.
Engine runs basically on water, so will not pass the
boiling point, and can even be cooled with excess water.
Good for boats, where water is an available resource, or could use recycled sewage water.

Why would one bother to dissolve the ingredients for the exothermic reaction, rather than simply carryhing each separately? Why do I want to carry the extra weight of water that's readily available on site? |

because the hydrogen is dangerous, whereas the hydrogen which is stored in water will not combust till the water releases it as bubbles. |

The hydorgen when burning reaches extremely high temperatures, for which to harness you need a special kind of motor. |
|
| |
But when burning submerged in water, the water will stop the heat from reaching over 100 degrees, and will boil the surrounding water instead, creating steam, while the small amount of water created by the reaction would join as a minute amount of steam too. |

Making steam engines is AFAIK a simple task. |

As written in the hbea description, for boats this would be great. If the gas is created at sea (using a sea-power or sea-based energy source) it could be desolved into surrounding sea-water and easily distributed (in floatable units). |

In the UK, long-distance express steam locomotives used to scoop up water from troughs between the rails.
Using this scheme, they could pick up fuel as well! |

The amount of H that can be solubulized into a ml of water at STP is not adequate to boil said ml of water. If we increase the pressure and decrease the temperature we can produce a slightly stronger fuel but it we are talking about energy density and efficiency comparable to wet newspaper. This idea is similar to "use wet newspapers to power a steam engine". |
