Pratt & Whitney has developed "greener" aircraft engine technology.
Pratt & Whitney has spent the better part of two decades developing the geared turbofan engine that burns 12 to 15 percent less fuel than other jet engines and cuts carbon dioxide emissions by 1,500 tons per plane per year.
Cool.
The whole technology is not based on developing new alternative fuels, but on doing old designs better. The turbofan design in today's engines have the fans that draw air into the combustion chamber and the turbines that generate the thrust spinning at the same speed. Pratt's new geared turbofan allows the fan to spin independently of the turbine, so that each may spin at their own optimal speeds. Thus, the fuel savings.
So much has been said about putting all our marbles in futuristic, undeveloped technologies. We should be doing a lot more of what Pratt has done.....improving the technologies we have today WHILE the new technologies are being developed.
