The bottom line, maybe. But what about all the working out, of getting it there. That might be where the issue lies.

Certainly it is. My point there is that if you have a domestic setup* which is designed to take a bottle of gas, then (subject to your normal checks), you can assume that everything that side of the valve is working safely.

Ooh no, steam is nasty dangerous stuff.

Will you need help selling tickets?

Wear protection. Coveralls treated with a salt, say potassium nitrate, has good preservative properties.

the gas industry had to start somewhere and via some mistakes("MISTAKES") have procedures and kit that minimizes the risks of repeating the HUGE BANGS

im not saying small scale gas should not be done but i am saying there is a lot of scope for tragedies or extreme embarrassment.

i recon i would personally go down the steam engine route for wood to motion but that also has a variety of risk factors ,rules n regs for good reasons etc etc .

Gasification to directly feed an infernal combustion engine is pretty well established and seems straightforward enough.

direct feed does seem fairly simple to do with no more risk than using petrol ,maybe less thinking about it .

Bigger risk from carbon monoxide than with petrol. Less risk of fire and explosion... as long as the gasifier is secure.

Take your gas filled air bed with you...


There is an obvious volumetric limitation to that, but are you persuaded by the safety considerations?

How about a really big airbed and a lot of hydrogen in the mix?
Tow it home with a robot piloted drone.

A general cylinder safety note from my years in a lab

1. Always store a cylinder of gas upright and chained in place - that way if the valve at the top goes, the cylinder tries to bury itself into the ground rather than whizzing around. Bear in mind a cylinder whizzing around one ground has a hell of a lot of mass and there are instances of them smashing through brick walls.

2. Never use a cylinder as a roller or anything other than a cylinder - valve damage and metal fatigue.

And not quite the same thing - but I am reminded of the taxi driver during the petrol crisis who filled a plastic dustbin with petrol.

Not all plastics are the same - different solvents dissolve different plastics.

How on earth do you run a motor on Woodgas - without carrying a tank of it ?

Those cars were run on either hydrogen or town gas.

You have a portable gasifier and make it on the hoof. It is nothing new: they did it during the war.

proper "not quite mad max" kit

a charcoal fueled steam wagon would be another transport/haulage alternative.until to the axle weight laws changed in the 1930's they were quite common and with a modern materials etc the chassis , box and pistons could be light so they could be made quite sporty.

it is hard to beat petrol/nitromethane for power and silly speeds but a 60 mph plodder fueled with wood heated steam seems plausible

wood to gas to turbine to electric to batteries to leccy motor has a loss at every stage

wood to liquid fuel to internal combustion engine driving vehicle seems worth looking into.iirc there is a way to distill trees into a fuel that will run a cossack or a t34 or a 1940's russian lorry .

the chap cracking wood distillates on youtube seems to have started playing with such things

i recon home compressed gas is really too dangeroos to learn as you go
