Jaguar XJ6 news - Bad apples power Jag - 2007

Read more on:

we’ve seen cars powered by burger grease, orange juice, hemp and something
called Jatropha Curcas seeds. Nope, still don’t know what they are.

what about rotting apples? In a move as selfless as it is eco-friendly,
Somerset farmer Henry Hobson has converted his Jaguar XJ6 to run off methane
produced from the decomposing fruit in his orchard.

science is simple enough: Hobson fills two underground tanks with apples from
his 10,000-tree orchard, and adds a soupcon of bacteria from cows’ intestines
(yes, seriously) to help the rotting along.

gas emitted from the decomposition is filtered through water to remove the
sulphur and carbon dioxide, leaving Hobson with lots of lovely pure methane.
And lots of lovely cheap fuel.

reckons that - discounting the £3,000 it cost to convert his Jag - he
saves more than two grand every year on fuel costs. And as an added bonus, the
big ol’ XJ6 is putting out about 10 per cent more power at very similar fuel
economy to before.

is apple-power the future? Hobson maintains that methane is 10 times more
efficient to produce than bio-diesel. And, as well as presumably filling the
air with the sweet smell of home-brew, his fuel has the advantage of keeping
the doctor well away.

if only we could harness all that methane that our cows produce. Volunteers,
