This common weed could soon be fuel for aircraft

Field pennycress is a gardener’s nightmare. It grows abundantly on farms, allotments and waste ground throughout Europe and North America. It smells when crushed and is known as stinkweed and when cows eat it, their milk is tainted. But this humble weed could soon be powering the energy transition. Its seeds have a very high oil content, about 50% higher than soybean which is a common base for biofuels.
