Day
Three
The morning started out much as yesterday had (minus
the baseball) with us trying various ways to improve
the suction for the vacuum, refine the pumping and cool
the water. Mike had been preparing a back-up chemical
cooling system and with us unable to get low enough
pressures to bring the boiling point of the water down
to air temperature to kick start the cooling, we didn’t
have much choice. We also didn’t have much time,
since the journey to the hottest part of Death Valley
would take a good few hours. Lunchtime was the deadline
for having the whole thing ready. It was all hands to
the pumps – or rather to the saws and drills as
we through together the wooden trolley that would carry
the fridge across the desert. It was close but we made
it, though without any time to check that the various
components were working. If the previous evening was
anything to go by, dismal failure was waiting for us
in Death Valley. Little did we know it would be one
of the funniest things any of us could remember, and
certainly in the top 5 ‘Funniest things ever to
have happened in Death Valley’ contest.
Now Death Valley is got to be one of the most spectacular
places on Earth. The flat white desert floor against
the rising dark mountain ranges that flank both sides
give you a sense of being from another planet. It also
makes for a vicious suntrap. But as well as the temperatures,
filming in Death Valley is no easy matter. For one thing,
you are given a ranger that tells you where you can
film and makes sure that you abide by the rule of not
going more than 50 m off the tarmac road. Also, you’re
not allowed to disturb the surface of the salty desert
crust, even though the next rainstorm will completely
reshape this jagged miniature landscape of cracked,
thrusted and heaved salt blocks. Our wooden wheeled
trolley certainly raised an eyebrow in this regard,
but the sight of Ellen putting on her copper tubing
basque and then her white space suit (a late design
change) presented enough of an enigma to make our ranger
curious about what on Earth we were planning. In the
end, to our astonishment, it all went to plan. Mike’s
fertiliser cooled the water, our frantic pumping gave
a decent partial vacuum and Ellen headed out across
the desert surface, as if powered by our magical mechanical
enema. For me, what made it a great moment wasn’t
that the temperature dropped as she went, but more that
the trolley slowly disintegrated en route, its wheels
first sagging, then tilting then falling off, forcing
a valiant Ellen to unceremoniously haul the thing to
its destination. The scientists, the production team,
the ranger and even some passing tourists that had stopped
to watch were in hysterics. Six hours ago few if any
of us gave this any hope of working. Even the fridge
had tried its best to self destruct on us. But it was
great to see that when you throw some basic science
and some enthusiastic determination at a problem, sometimes
it can actually come off. Wonderful stuff!
