With so much volatility in the price of oil over the last decade, who can blame the airline industry for “going big” these past couple months and placing bets on emerging renewable jet fuel companies?

The list of deals is long: AltAir signing an MOU with 14 airlines to supply camelina-based fuel, BioJet and Great Plains working together to develop their own green fuel derived from camelina, Kingfisher Airlines working with three companies on R&D for renewable jet fuel, and Qatar Airways leading a consortium to investigate potential biofuels, just to name a few.

A Qatar Airways flight from London to Qatar has become the first passenger plane to be powered by cleaner-burning natural gas that was converted to kerosene.

“Today’s flight opens the door to an alternative to oil-based aviation fuel,” said Malcom Brinded, international executive director of Royal Dutch Shell, which is partnering with Qatar Petroleum to produce so-called gas-to-liquid (GTL) kerosene from Qatar’s abundant natural gas reserves. (more…)

It’s been a mystery: how can our teeth withstand such an enormous amount of pressure, over many years, when tooth enamel is only about as strong as glass?

A new study by Prof. Herzl Chai of Tel Aviv University’s School of Mechanical Engineering and his colleagues at the National Institute of Standards and Technology and George Washington University gives the answer. And it has applications in the field of green aeronautics.

The researchers applied varying degrees of mechanical pressure to hundreds of extracted teeth, and studied what occurred on the surface and deep inside them.

Biofuels – made from algae and non-food plants – are emerging as a potentially viable alternative to conventional jet fuels. Although big challenges remain, the reductions in greenhouse gas emissions could be major.

Earlier this year, a Continental jet accelerated down the runway at George Bush Intercontinental Airport in Houston. Nothing out of the ordinary for Capt. Rich Jankowski, who countless times in his 38-year career had eased such two-engine Boeing 737-800s into the sky. Except on this experimental flight, one of the engines Jankowski relied on was burning fuel derived from microscopic algae to push the 45-ton aircraft into the air and keep it aloft — a first in aviation history.

Seambiotic, a Tel Aviv, Israel-based leader in the development and production of marine microalgae for the nutraceutical and biofuel industries, announced today that its US subsidiary, Seambiotic USA, has entered into an agreement with NASA Glenn Research Center to develop an on-going collaborative R&D program for optimization of open-pond microalgae growth processes.

Under a Space Act Agreement, NASA is partnering with Seambiotic USA to model growth processes for microalgae for use as aviation biofuel feedstock,” said Prof. Ami Ben-Amotz, Chief Scientific Adviser to Seambiotic.
