Electric Planes: The Trillion-Dollar Race Flying Under the Radar


I live in a small village in the Swiss mountains - peaceful, pristine, the kind of place you’d expect to be untouched by global chaos. But even here, signs of a changing world drift in on the wind.


Literally. Last spring, red dust from the Sahara settled over the snow. And this summer, we woke up to an unpleasant scent, smoke from Canadian wildfires that had drifted across the Atlantic and into Europe.


The skies above our remote village carried more than clouds, yes, they carried a warning.

That’s the moment it hit me: even here, where cows outnumber cars, aviation's impact on the world can’t be ignored.


But this story isn’t about the past. It’s about the aircraft that will define our future.


Let me take you on a journey.


From Laughable to Lift-Off: The Impossible Physics of Electric Flight


For decades, engineers said it couldn’t be done.


Flight is about weight. Jet fuel offers 40 times the energy density of traditional batteries. A battery-powered plane, they argued, would never leave the ground.

But they didn’t account for three quiet revolutions:

  • Battery energy density improved 5–8% every year

  • Electric motors hit 95% efficiency versus 35% for turbines

  • Distributed propulsion reshapes aircraft design


When I first heard about this, I was skeptical. Then came Alice. What drew laughter once now draws venture capital.

The sky has new rules, and they favor electrons.


Alice in the Sky: The Plane That Changed Everything


In 2019, Israeli startup Eviation introduced Alice, a fully electric plane that could fly 440 miles, carry nine passengers, and operate at 70% lower cost.

Within months, aviation titans were scrambling:

  • Boeing, Airbus, Rolls-Royce announced electric programs

  • United Airlines ordered 100 electric aircraft

  • FedEx joined the cargo revolution


Why the rush?

  • Operating costs dropped from $2,000 to $200 per flight hour

  • Maintenance cycles extended by 10x

  • Noise levels fell below 60 decibels


I realized this wasn’t a tech demo, it was a business model.

One prototype flipped an industry’s balance sheet.

Nothing spreads faster than fear of missing profit.


The Secret of Blown Lift: Why Electric Planes Can Do More with Less


Traditional jet engines need to be large and heavy. Electric motors don’t.


You can place dozens of smaller motors along the wing; this creates blown lift.

More air over the wing = more lift at lower speeds.

Tiny Motors, Huge Impact: The Power of Blown Lift


Electric motors come in pocket sizes, so designers sprinkle them along the wing like breadcrumbs.

The result, blown lift, pushes more air over the surface, letting planes leap off shorter runways and sip power aloft.


NASA’s X‑57 Maxwell proved the concept, slashing take‑off distance by 58 % and boosting cruise efficiency fivefold while lowering stall speed to 48 knots.


Distributed thrust turns geography into opportunity. Smaller airports. Shorter routes. More direct connections.


The Battery Revolution That Quietly Took Off


Aviation batteries endure brutal duty cycles, survive ±40 °C, and must stay calm at 30 000 feet.


Solid‑state cells killed thermal runaway, silicon anodes tripled density, and AI charging stretched lifespans tenfold.


Energy storage jumped from 100 Wh/kg in 2010 to 500 Wh/kg today, and labs target 800 Wh/kg before 2030.


Every 5 % gain in density buys another regional route.

Progress is now a schedule, not a wish.


Where Electric Flight Will Take Off First


Not across oceans. Not yet.

Electric planes will dominate routes under 500 miles—which make up half of all global flights. These are the least efficient for jet engines. But they’re the sweet spot for electric:

  • No warm-up time

  • Peak torque at takeoff

  • Regenerative braking during descent


In Norway, all domestic flights will be electric by 2040. Scotland’s plan kicks in by 2045. California mandates 30% by 2035.

The map is redrawing itself.


Hydrogen’s Hype, Battery’s Reality


Everyone thought hydrogen would be aviation’s green savior. But the physics disagree: Hydrogen dazzled PowerPoint slides but stumbled on the ramp.

It demands cryogenic tanks heavier than the fuel and billion‑dollar airport retrofits, while round‑trip efficiency barely touches thirty percent.

Batteries plug into existing grids at ninety percent efficiency, scale by module, and avoid deep‑freeze complexity.


Orders tell the tale: more than 2 000 electric aircraft on backlog versus barely a dozen hydrogen bets.

Physics may bend, but economics snaps decisions into place.


Shortcut to the Skies: Certification Innovation


New planes typically face a 10-year approval process. Electric innovators found a shortcut: convert existing planes.

  • A Cessna Caravan becomes an eCaravan

  • A Twin Otter becomes an eTwin Otter


That cuts the timeline to 3 years:

  • No aerodynamic redesigns

  • Just new propulsion certification

  • Pilot training remains intact


Harbour Air proved it in 2019. By 2025, 50+ electric routes will be active.


The True Economics of Electric Flight


Airlines focus on fuel. But fuel is only 30% of operating cost.

Electric flight cuts deeper:

  • Turbines = 2,000 moving parts

  • Electric motors = 1

  • No oil. No filters. No hot section inspections


The result?

  • Turbine overhaul: $2M every 3,000 hours

  • Electric motor: $50K every 10,000 hours

  • Daily savings: $8,000 per plane


Multiply that by 100 aircraft? $292 million saved per year.


The Grid Is Ready (And Airports Are Profiting)


Critics say airports need massive upgrades. That’s false.

A typical short-haul flight needs 500 kWh—equal to 10 Tesla Superchargers. Most airports already have that capacity.

And the strategy?

  • Start with overnight charging

  • Expand with solar car parks

  • Sell electricity at 3x market rates


Airports don’t just save—they profit.


The Flight Plan Ahead in my perspective:


Mark the milestones:

  • 2024 – first scheduled electric routes

  • 2026 – triple‑digit fleets in service

  • 2028 – regional jets start retirement

  • 2030 – 1 000‑mile battery range achieved

  • 2035 – half of short‑haul flights go electric


Property near small airfields will surge, cargo will skip hubs, and rural economies will reconnect.


Change drifts even into alpine valleys—this time carrying cleaner air.

The question is no longer if electric aviation will happen but who profits first.

Will your portfolio make the boarding call?
