The Sahara desert is a truly vast environment - with sand dunes reaching 180 meters high, scorching temperatures and fierce sand storms it provides a real test for any method of transportation.

So how, does the eco-option for crossing this massive and barren landscape stack up against more modern technologies? This is a question posed regularly at EcoWorldly and I recently had the opportunity to put it to the test during a journey which took me from the ‘Gateway to the Sahara’ in Douz, Southern Tunisia, to Matmata, a desert village of cave dwellings famous for providing the location for Luke Skywalker’s home in the Star Wars movies.

(Note: the author only discovered this fact after arriving - this was not a pilgrimage.)

Our local guides presented us with two options: The camel - trusty ship of the desert, as used for centuries by desert dwellers, and the equally ubiquitous Toyota Land Cruiser 4×4 – the motor vehicle of choice for those needing to travel across challenging terrain.

We gave both modes of transport a thorough workout in an attempt to compare our eco camel against it’s more modern counterpart, making assessments on comfort, emissions, speed, reliability, off-road capability and fuel consumption. The testing process consisted of two days of travel across the desert by camel, camping overnight in the dunes, followed by a further day’s journey in the Land Cruiser.

What do they do with chocolate products they can’t sell? Off to the landfill to decompose and create methane. Wish they could just send it to me. Two young Britons, Andy Pag and John Grimshaw, have traveled more than 4,000 miles across the Sahara using such chocolate as fuel.

The two decided to prove the viability of different kinds of feedstock to produce biofuels, especially biodiesel and ethanol. They’ve done that, traveling from Poole, England to Timbuktu, Mali, 4,473 miles, using 396 gallons of fuel made from three tons of discarded chocolate.

The truck was salvaged from a scrap yard, repaired and fitted for the long trip. It will remain in Timbuktu, a donation to a local charity. The crew will also set up a small processing unit to convert waste oil products into fuel.
