[After Chimera, a fire-breathing female monster in Greek mythology who had a lion's head, a goat's body, and a serpent's tail. From Greek khimaira (she-goat), ultimately from the Indo-European root ghei- (winter) that is the ancestor of words such as chimera (literally a female animal that is one winter, or one year old), hibernate, and the Himalayas, from Sanskrit him (snow) + alaya (abode).]
"The government subsidies [for bio-fuel] may quickly dry up once policymakers face up to the reality of their euphoric chimera, and food shortages threaten political stability and national security."
