In a 747 containing a stunning 5% biofuel, Virgin Atlantic proved that you can indeed fly a plane on bio-diesel.
There was actually some question as to whether it would be possible actually, because jet fuel has to stay liquid and levitra pfizer 50 mg non-viscous at extremely low temperatures. Most bio-diesel at those temperatures would become too thick to feed into the engines. However, a young biofuel startup in Seattle, Imperium, created a mixture that when mixed in ratios up to 40:60 with jet fuel, stayed usable.
The Virgin flight ran one of the four engines on a 20:80 mix of the Imperium fuel, for an overall replacement of it's cool info viagra 1/20th of the fuel used on the www.sinai.org.il flight. Of course, with recent fears over the sustainability of bio-fuels due to replacement of food crops and deforestation, it's unclear whether bio-diesel is http://operacijatrijumf.net/cialis-price going to escape from this battle in tact. Only if large-scale production of bio-diesel from algae hits the mainstream will we see this technology taking off.
Ethanol has more of a future, as it's easier to buy cheap online levitra produce it in mass quantities from waste products. However, ethanol contains less energy than bio-diesel per gram, which is a trade-off the airline industry is unlikely to make, even if they can get it to run in jet engines.
