At 5% per year, you get a 63% improvement over ten years. And we're looking for orders of magnitude in battery improvements? You know what an order of magnitude is? It's ten times more, not 0.63 times more. We need an order of magnitude so that the range is much better than an ICE airplane, since we really don't want to fly for a couple of hours and them wait the rest of the day for the thing to recharge. A ten-hour range would solve that.Battery teck is close to bieng viable for some
aviation aplications.......Currently batteryies are improving at about 5%
per year,or more over the last 10 years.
Math and physics are SO inconvenient. Reality hurts.
I'm not against electric vehicles. Really. ICE are dirty and noisy and inefficient and their vibrations destroy stuff. I should know, I am a retired aircraft maintenance engineer (Canadian). And a pilot and former flight instructor.
But electric airplanes are a long ways from being practical and affordable. It will take a lot of time, or some breakthrough technology, to advance them much more. Besides that, what will happen when the environmental activists wake up to the devastation caused by mining the special stuff needed for these motors and batteries? It'll get really expensive, that's what.
We can rattle on and on about what's happening in the electric world. That sort of talk has been going on a long time already and we've seen incremental advances, not a breakthrough. I will remind you that the lithium ion battery was invented 54 years ago. The nickel-cadmium battery was invented 130 years ago. Development is not that rapid.
