AMSTERDAM - Air France unit KLM Royal Dutch Airlines was the first airline to make a passenger flight which partly used biokerosene on Monday.

During the 1.5 hour flight above the Netherlands, one engines of the Boeing 747 ran on a mixture of 50 percent sustainable biofuel and 50 percent on traditional kerosene. The other three engines ran on 100 percent normal kerosene. KLM Chief Executive Peter Hartman said the biofuel used on the flight reduces CO2 emissions by up to 80 percent compared to conventional kerosene. "We hope to receive certification at the end of 2010. Then the question is: how fast can we produce it?"

Aircraft account for an estimated 2-4 percent of global carbon dioxide (CO2) emissions, which scientists say could cause global temperatures to rise, triggering widespread disease, famine, flooding and drought.

Experts say global aviation emissions could reach 2.4 billion tonnes in 2050, which would be 15-20 percent of all CO2 permitted under a global agreement and a nearly four-fold increase on current levels.

KLM, North Sea Petroleum and Spring Associates on Monday founded the SkyEnergy consortium, targeting sufficient supply of biofuels for airplanes.

"We have demonstrated that it is possible. Government, industry and society at large must now join forces to ensure that we quickly gain access to a continuous supply of biofuel," Hartman said.

ustvari nisam skontao jesi ovo stavila u pozitivnom smislu ili negativnom wink.gif ili samo ko èinjenicu
sama proizvodnaj biogoriva isto zagadjuje, a da ne govorimo o problemu hrane

http://www.izvorienergije.com/biogoriva.html

"Stoga se, barem za sada moramo složiti s veæ spomenutom izjavom kako je svako dijete koje umre od gladi u današnjem svijetu zapravo ubijeno dijete, a èemu æe, po svemu sudeæi, proizvodnja biogoriva još više pridonijeti. "

pa ce onda biti više slika kako lešinari stoje kraj gladne djece... a mi cemo se zgražati...

nemate pojma. rjesenje su jednostanicne alge. (to cu ja radit u skoroj buducnosti smile.gif )
moze se proizvest i do 70% vise ulja nego od kukuruza ili uljane repice na vrlo malo povrsine..
plus što nema otpadnih proizvoda jer je sve iskoristivo,
dobis jos i glicerol i proteinski ostatak koji se koristi npr za riblju hranu ili gnojivo...a sav CO2 koji ode u atmosferu
se ponovno resorbira u alge i druge biljke tako da je po tom pitanju neutralno. cak se moze proizvodit kao takav, i kisik i vodik...
a jednostanicne alge ljudi ne jedu tako da
nema straha ko za kuruzu i soju.. a mogu se uzgajat i na kanalizacijskim i otpadnim vodama, treba ti jos samo voda i sunce.. i to morska voda..
samo pitajte google: algal biofuel

algal fuel
