We won't have electric airplanes until battery tech improves
Today’s commercial airliners are not exactly fuel efficient. The average 747, for example, burns through a gallon of kerosene-based fuel every second that it flies. And with 8.2 billion people expected to take to the skies annually by 2037, carbon-free alternatives to Jet A-1 will be necessary in order to offset the industry’s impact on global warming. We are nearing the age of electric airplanes. (www.engadget.com) Más...Sort type: [Top] [Newest]
The first statement is false on its own, Todays jet airliners are EXTREMLY fuel efficient. some of these aircraft have a take off weight of over 400,000 pounds and the 74 can go almost 1,000,000 gross weight. the absolute fact is electric "vehicles" may work at some point but will never be able to carry the large payloads that modern airplanes do now. Think about how heavy batteries are and then think about how many it would take to propel a large loaded airliner across the ocean. So PAX or cargo would have to be sacrificed to accommodate the weight of internal batteries. you can challenge me on this, and no, I'm not an aerodynamic engineer, just a lowly jet pilot that can think logically.,
Duh.... its been the problem all along.. waiting..
I recall that my B-747 would burn an average of 10,000lbs of kerosene each hour - that's a lot of carbon!

Thanks for the post as am so over these dumb assed people as its doing the same thing its done since this thing was covered everywhere with ice. It is evolving nothing can stop it. It could at any time start going the other way. It has started a few times renewing the ice and it could go back to that again. There is no proof it could not.
Well said!
