Many American passenger cars and light duty trucks can operate on either gasoline or a bioethanol/gasoline blend called E-85 — 85 percent ethanol/15 percent gasoline. While E-85 is not a pure carbon neutral fuel it does produce low emissions. The big downside to ethanol is it is less energy-dense than other fuels, so it reduces fuel economy by 25% to 30%. With gasoline prices hovering around $2 a gallon E-85 is not competitively priced. And good luck finding a gas station that sells it outside the Midwest farming states.
Naturalistic theatre, which flowered in the late 19th century, made rhetoric obsolete, requiring the actor to hide virtuoso performing skills by creating the illusion of everyday behaviour. This meant that more weight was given to the actor’s depictions of psychological attributes.
