Hi all,
I am designing a backpack to allow me to go adventuring without having to be plugged into the supply from my mighty ironclad, but I want some suggestions on power, I'm thinking candle powered steam, or gas lamp, but can't decide, any opinions on which would look better and how to achieve the look would be appreciated.

Many thanks for your time

A miniature Walter turbine?  using stabilised hydrogen peroxide as an oxidiser.  The genuine Walter turbine wasn't developed until 1933, but you could always theorise a steampunk Unobtanium fuel for chemically generating steam to drive a miniature turbine.  Using a chemical oxidiser would permit the same power source to operate at all altitudes and even underwater without being dependent on atmispheric oxygen.

Are you thinking of a backpack, beltpack, shoulder case, etc.? and what sort of devices do you need to power?

Thanks Mr salt, that's a really cool idea, I was planning on building a backpack, and it would be too power my weapons and possibly a face mask, the usual items an adventurer requires, I'm basing it on an old clansman radio frame.

Thanks again for your suggestion,

Read up on Narcís Monturiol i Estarriol's wooden double-hulled steam-powered submarine Ictineo II for an anærobic steam boiler that won't deplete your stockpiles of Unobtainium or Handwavium.

A lot depends on exactly what sort of power you need. eg total energy storage capacity, the peak and average power demand and the degree of fluctuation.

For example steam locomotives tend to have fire-tube type boilers which can accumulate a lot of spare capacity for stopping, starting, climbing inclines etc but tend to be relatively heavy and bulky and take a long time to get going.

Water tube or similar types can generate steam on demand but tend not to have much spare capacity.

Another important consideration is the energy density of your fuel. Apart from nuclear fuels Hydrogen has the best energy density but is not easy to store and transport in a conveniently sized package. Gasoline and diesel/kerosene are the next best and, being liquids at standard temperature and pressure, are reasonably practical to store and carry, natural gas and propane are pretty close behind. Even the best modern batteries have an energy density several orders of magnitude worse than any combustible fuel.

The other issue is how you convert your stored energy, in whatever form, to the energy that you can make use of.

Batteries have the advantage that they provide electrical energy as DC voltage without any intermediate steps, which makes them good for small, relatively low powered devices but don't scale up very well.

What about mechanically-generated power?
I'm thinking like the backpack-sized spraytanks with the pump handle poking out to the front to be pumped up and down - only converted to spin a generator or perhaps an hydraulic pump?

A kink-spring powerpack? (ref. The Windup Girl).

A power source powered by kink? That would certainly be a spanking-new concept!

Seriously, I have got to stop doing that!

Use these to power your field equipment:


Or if you need compressed air carry compressed air. Carrying a steam boiler on your back dangerous.

I think a shotgun-shell belt with ye-olde batteries in the loops, connected by cable-covered wire would be pretty damn epic.

Battery belt-I like that idea!

Those old telephone batteries shown above are about the size of tall-boy beer cans, so they wouldn't fit in a stock bandoleer; it would have to be custom.

Google beer bandolier, it may need some mods to work with your kit, or be reengineered for your particular batteries.

What about a candle powered Peltier generator?
