Key points:
• Gearboxes with high step-up ratios tend to give horizontal wind turbines poor efficiency when wind speeds are low.
• One way to eliminate wind-turbine bird kills: Locate turbines far out at sea.

A first: UAV runs on biofuel

Jared Rader — Thu, 08 Dec 2011 09:28:46 -0600

A Northrop Grumman MQ-8B Fire Scout recently completed the first unmanned biofuel flight. The unmanned aerial vehicle (UAV) flew from an airfield in Maryland on a combination of JP-5 aviation fuel and fuel made from camelliea, a flowering plant native to Asia.

Cellulose fuels won’t meet government goals

Jared Rader — Thu, 17 Nov 2011 08:43:06 -0600

The U. S. government‘s Renewable Fuel Standard mandates that by 2022, the U. S. use 15 billion gallons of corn-based ethanol, 1 billion gallons of biodiesel, and 16 billion gallons of cellulosic fuels. A recent peer-reviewed report from the National Academy of Science prepared for Congress concludes that the goals for corn-based ethanol and biodiesel can be met, but those for cellulosic fuels are probably unreachable.
