Tesla Electric Airplane? Elon Musk sees electric aircraft in 5 years

Tesla CEO Elon Musk started discussing the potential for electric airplanes, which he thinks could be viable in about 5 years.

Could a Tesla airplane be in Musk’s plans?

We are already starting to see electric airplane programs, like the Pipistrel Alpha Electro all-electric plane and the Siemens and Magnus’ eFusion, but battery technology still needs to improve in order to have commercial aircraft like we have today.

Musk has long been talking about all modes of transport going electric at some point – except for rockets.

Years ago, the CEO of Tesla and SpaceX even said that he had a design for electric vertical take-off and landing (VTOL) aircraft – though he never elaborated on plans to bring the aircraft to production.

In order for his design to work, Musk said that the energy density of batteries needs to improve.

This weekend, Musk updated his expected timeline for the energy density to improve enough to enable battery-powered airplanes:

Musk explains that jet fuel beats batteries when it comes to energy density, but the efficiency gains mean that you don’t need as much energetic potential:

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

When he revealed that he had a design for an electric VTOL aircraft, Musk estimated that Li-Ion batteries would need to achieve a 400 Wh/kg energy density in order for batteries to beat kerosene and his electric aircraft to be viable.

Today, battery cells with high cycles are achieving about 300 Wh/kg of energy density.

Do you think Tesla will ever expand to electric aircraft?

Electrek’s Take

Over the last few years, I’ve seen a surprising number of companies unveiling eVTOL aircraft designs and even a few working prototypes.

There has been a lot of money flowing to the startups developing those vehicles.

It looks like they have been developing all the subsystems they need to build such an aircraft in order to be ready once the battery technology can catch up.

Tesla is definitely at the forefront of battery technology and it could be an interesting new industry for the company, but I doubt it would happen.

The automaker could maybe eventually supply the battery cells or battery packs for those electric aircraft, but I doubt Tesla would be involved more than that.

Although, it could be an interesting project combining the expertise in aerospace and batteries of Musk’s two main companies, SpaceX and Tesla.

Either way, if battery energy density is improving by over 30 percent over the next 5 years, it would not only potentially result in commercial electric planes, but it would also have an impact on Tesla’s cars and other electric vehicles – making EVs cheaper, lighter, and with the potential for longer range.
