Alternative Fuels for Jet Travel in Our Future?

Environmental activists have long focused criticism on the amount of fuel consumed by cross-country and international jet travel, but government and academic researchers announce that they are researching alternative fuels for jets. A usable product is years away, but the length of time such an endeavor takes is only one of the many challenges facing development of these alternative fuels:

• Such fuels are even more expensive than Jet A right now.
• The fuels are difficult to transport and manage in harsh weather conditions, making snow-prone northern climes more costly for such fuel usage.
• Some of the alterna-fuels, such as biodiesel, freeze at lower temperatures – making high altitudes "interesting" (tm Peter Kirsch)

Regardless, the inquiry is a positive development. TAL hopes the project proceeds apace and leads to a usable product soon.
