The Tractor Factor in New Zealand

Grove Mill, the world's first Carbon Zero winery, has modified a tractor to run on vine prunings, which as a tractor is often going six hours a day they consider well worth the cost. Although we had visions of this new tractor looking rather like Stephenson's rocket it turns out that the vine prunings undergo gasification first and the result can then be used as fuel. But the real pity is that those steaks grilled over the vine cuttings will loose that unique tangy flavour that is so delicious... Still, perhaps that's progress, perhaps not.
