SANTIAGO ALVAREZ, THE GAS VANS 379
Illustration 27: A Hypothetical Possibility. A Saurer truck equipped
with a wood gas generator placed between the driver’s cabin and the
cargo box. The gas generator’s gases are highly toxic and almost instantly
lethal. This gas is piped through a valve permitting to switch
the gas between either the engine or the cargo box (or both, then leading
to a reduced engine power). The gas enters the cargo box through a
horizontal pipe underneath the wooden grate. This way no objects can
fall or fluids flow into it, nor can the victims reach it through the grate.
Excess gas can escape through a small opening somewhere in the
walls or doors of the cargo box (as in this drawing). The floor could
and would still have an opening, but merely for cleaning and draining
purposes (not shown here). (Author’s drawing.)
