Electric airplanes......

Even with all available knowledge today we can't yet get a 2 ton 5 passenger automobile to go 500 kms (under $150K anyway). Of course electric propulsion will eventually be viable but it's going to take decades to happen..

"Electric" technology is a stepping stone to something better. Anything that takes hours to charge is simply not viable for airlines that need to land and take off again within the hour. Maybe possible for private aviation but I believe something "instant" needs to be realized. I like hydrogen fuel-cell better, fast charging but it's all talk so far. Biggest challenge with

Hybrids are going to come first  . And as the technology improves,  The power generated per kilogram with the present technology is way to low. There are many viable projects happening now through the hybrid technology which presently are designing much lighter  electric motors to generate the power for non commercial size planes .    I think the bomber may be right for

Sir: Perhaps for a Cessna little plane riding around the corner but right now it might be possibly a risky decision to go for electric planes at this moment unless you have an intelligent sophisticated secured back up plan?  Electric planes might not be feasibles near Alaska state or Yukon during winter months? Smartly may be wait two or three decades as the technology will drastically

right, don’t forget the weight of the battery one of the best battery (lithium - sulfur) is 1.8 MJ/kg and the  airplane fuel is 43.5 MJ/kg. The A220 as a 17200kg tank with an efficiency of 30% (need to be verified) it’s a 5200kg net and a 77% electric efficiency (convertion lost) you need a 125700 kg battery!!
