Elon Musk Hints That Tesla Could Make Electric Airplanes In Just Five Years

Elon Musk, co-founder and chief executive of Tesla Inc (NASDAQ: TSLA) founder, believes battery-powered electric airplanes could be viable in about five years.

Replying to a tweet on Sunday from a user who inquired whether it is possible for planes to fly off a battery, the electric car entrepreneur said that it will be a while before battery energy density improves enough to offer acceptable range.

“Is it possible for planes to fly off of a battery? Or is there not a powerful enough battery yet?” Twitch streamer Ninja inquired. “Yes, but still a bit too limited on a range,” Musk replied. “That will change in coming years as battery energy density improves.”



The rocket scientist went on to say that although jet fuel is more energy dense than Li-ion batteries when it comes to energy density, the efficiency gains mean that so much energy potential isn’t needed.

“Jet A (kerosene) has much higher energy density than Li-ion batteries, electric motors weigh much less and convert stored energy to motion better than combustion engines,” Musk said.

Based on some math that he said he did a decade ago; Musk estimates batteries will be able to support planes in about five years. “FWIW, based on calcs I did 10 years ago, cross-over point for Li-ion beating kerosene is ~400 Wh/kg. High cycle batteries are just over 300 Wh/kg today, but probably exceed 400 in ~5 years,” he wrote.

With the global aviation industry producing around 12% of carbon dioxide emissions from all transport sources, such an invention could drastically help in the fight against climate change.
